======================================================================== * gcc README ======================================================================== This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually. ======================================================================== * gcc contrib/unicode/README ======================================================================== This directory contains a mechanism for GCC to have its own internal implementation of wcwidth functionality. (cpp_wcwidth () in libcpp/charset.c). The idea is to produce the necessary lookup table (../../libcpp/generated_cpp_wcwidth.h) in a reproducible way, starting from the following files that are distributed by the Unicode Consortium: ftp://ftp.unicode.org/Public/UNIDATA/UnicodeData.txt ftp://ftp.unicode.org/Public/UNIDATA/EastAsianWidth.txt ftp://ftp.unicode.org/Public/UNIDATA/PropList.txt These three files have been added to source control in this directory; please see unicode-license.txt for the relevant copyright information. In order to keep in sync with glibc's wcwidth as much as possible, it is desirable for the logic that processes the Unicode data to be the same as glibc's. To that end, we also put in this directory, in the from_glibc/ directory, the glibc python code that implements their logic. This code was copied verbatim from glibc, and it can be updated at any time from the glibc source code repository. The files copied from that respository are: localedata/unicode-gen/unicode_utils.py localedata/unicode-gen/utf8_gen.py And the most recent versions added to GCC are from glibc git commit: f6032247061fb37d59565f2e9667e242c8a98e76 Finally, the script gen_wcwidth.py found here contains the GCC-specific code to map glibc's output to the lookup tables we require. This script should not need to change, unless there are structural changes to the Unicode data files or to the glibc code. The procedure to update GCC's wcwidth tables is the following: 1. Update the three Unicode data files from the above URLs. 2. Update the two glibc files in from_glibc/ from glibc's git. Update the commit number above in this README. 3. Run ./gen_wcwidth.py X.Y > ../../libcpp/generated_cpp_wcwidth.h (where X.Y is the version of the Unicode standard corresponding to the Unicode data files being used, most recently, 13.0.0). After that, GCC's wcwidth will match the most recent glibc. ======================================================================== * gcc gcc/README.Portability ======================================================================== Copyright (C) 2000-2021 Free Software Foundation, Inc. This file is intended to contain a few notes about writing C code within GCC so that it compiles without error on the full range of compilers GCC needs to be able to compile on. The problem is that many ISO-standard constructs are not accepted by either old or buggy compilers, and we keep getting bitten by them. This knowledge until now has been sparsely spread around, so I thought I'd collect it in one useful place. Please add and correct any problems as you come across them. I'm going to start from a base of the ISO C90 standard, since that is probably what most people code to naturally. Obviously using constructs introduced after that is not a good idea. For the complete coding style conventions used in GCC, please read http://gcc.gnu.org/codingconventions.html String literals --------------- Some compilers like MSVC++ have fairly low limits on the maximum length of a string literal; 509 is the lowest we've come across. You may need to break up a long printf statement into many smaller ones. Empty macro arguments --------------------- ISO C (6.8.3 in the 1990 standard) specifies the following: If (before argument substitution) any argument consists of no preprocessing tokens, the behavior is undefined. This was relaxed by ISO C99, but some older compilers emit an error, so code like #define foo(x, y) x y foo (bar, ) needs to be coded in some other way. Avoid unnecessary test before free ---------------------------------- Since SunOS 4 stopped being a reasonable portability target, (which happened around 2007) there has been no need to guard against "free (NULL)". Thus, any guard like the following constitutes a redundant test: if (P) free (P); It is better to avoid the test.[*] Instead, simply free P, regardless of whether it is NULL. [*] However, if your profiling exposes a test like this in a performance-critical loop, say where P is nearly always NULL, and the cost of calling free on a NULL pointer would be prohibitively high, consider using __builtin_expect, e.g., like this: if (__builtin_expect (ptr != NULL, 0)) free (ptr); Trigraphs --------- You weren't going to use them anyway, but some otherwise ISO C compliant compilers do not accept trigraphs. Suffixes on Integer Constants ----------------------------- You should never use a 'l' suffix on integer constants ('L' is fine), since it can easily be confused with the number '1'. Common Coding Pitfalls ====================== errno ----- errno might be declared as a macro. Implicit int ------------ In C, the 'int' keyword can often be omitted from type declarations. For instance, you can write unsigned variable; as shorthand for unsigned int variable; There are several places where this can cause trouble. First, suppose 'variable' is a long; then you might think (unsigned) variable would convert it to unsigned long. It does not. It converts to unsigned int. This mostly causes problems on 64-bit platforms, where long and int are not the same size. Second, if you write a function definition with no return type at all: operate (int a, int b) { ... } that function is expected to return int, *not* void. GCC will warn about this. Implicit function declarations always have return type int. So if you correct the above definition to void operate (int a, int b) ... but operate() is called above its definition, you will get an error about a "type mismatch with previous implicit declaration". The cure is to prototype all functions at the top of the file, or in an appropriate header. Char vs unsigned char vs int ---------------------------- In C, unqualified 'char' may be either signed or unsigned; it is the implementation's choice. When you are processing 7-bit ASCII, it does not matter. But when your program must handle arbitrary binary data, or fully 8-bit character sets, you have a problem. The most obvious issue is if you have a look-up table indexed by characters. For instance, the character '\341' in ISO Latin 1 is SMALL LETTER A WITH ACUTE ACCENT. In the proper locale, isalpha('\341') will be true. But if you read '\341' from a file and store it in a plain char, isalpha(c) may look up character 225, or it may look up character -31. And the ctype table has no entry at offset -31, so your program will crash. (If you're lucky.) It is wise to use unsigned char everywhere you possibly can. This avoids all these problems. Unfortunately, the routines in take plain char arguments, so you have to remember to cast them back and forth - or avoid the use of strxxx() functions, which is probably a good idea anyway. Another common mistake is to use either char or unsigned char to receive the result of getc() or related stdio functions. They may return EOF, which is outside the range of values representable by char. If you use char, some legal character value may be confused with EOF, such as '\377' (SMALL LETTER Y WITH UMLAUT, in Latin-1). The correct choice is int. A more subtle version of the same mistake might look like this: unsigned char pushback[NPUSHBACK]; int pbidx; #define unget(c) (assert(pbidx < NPUSHBACK), pushback[pbidx++] = (c)) #define get(c) (pbidx ? pushback[--pbidx] : getchar()) ... unget(EOF); which will mysteriously turn a pushed-back EOF into a SMALL LETTER Y WITH UMLAUT. Other common pitfalls --------------------- o Expecting 'plain' char to be either sign or unsigned extending. o Shifting an item by a negative amount or by greater than or equal to the number of bits in a type (expecting shifts by 32 to be sensible has caused quite a number of bugs at least in the early days). o Expecting ints shifted right to be sign extended. o Modifying the same value twice within one sequence point. o Host vs. target floating point representation, including emitting NaNs and Infinities in a form that the assembler handles. o qsort being an unstable sort function (unstable in the sense that multiple items that sort the same may be sorted in different orders by different qsort functions). o Passing incorrect types to fprintf and friends. o Adding a function declaration for a module declared in another file to a .c file instead of to a .h file. ======================================================================== * gcc gcc/config/arm/README-interworking ======================================================================== Arm / Thumb Interworking ======================== The Cygnus GNU Pro Toolkit for the ARM7T processor supports function calls between code compiled for the ARM instruction set and code compiled for the Thumb instruction set and vice versa. This document describes how that interworking support operates and explains the command line switches that should be used in order to produce working programs. Note: The Cygnus GNU Pro Toolkit does not support switching between compiling for the ARM instruction set and the Thumb instruction set on anything other than a per file basis. There are in fact two completely separate compilers, one that produces ARM assembler instructions and one that produces Thumb assembler instructions. The two compilers share the same assembler, linker and so on. 1. Explicit interworking support for C and C++ files ==================================================== By default if a file is compiled without any special command line switches then the code produced will not support interworking. Provided that a program is made up entirely from object files and libraries produced in this way and which contain either exclusively ARM instructions or exclusively Thumb instructions then this will not matter and a working executable will be created. If an attempt is made to link together mixed ARM and Thumb object files and libraries, then warning messages will be produced by the linker and a non-working executable will be created. In order to produce code which does support interworking it should be compiled with the -mthumb-interwork command line option. Provided that a program is made up entirely from object files and libraries built with this command line switch a working executable will be produced, even if both ARM and Thumb instructions are used by the various components of the program. (No warning messages will be produced by the linker either). Note that specifying -mthumb-interwork does result in slightly larger, slower code being produced. This is why interworking support must be specifically enabled by a switch. 2. Explicit interworking support for assembler files ==================================================== If assembler files are to be included into an interworking program then the following rules must be obeyed: * Any externally visible functions must return by using the BX instruction. * Normal function calls can just use the BL instruction. The linker will automatically insert code to switch between ARM and Thumb modes as necessary. * Calls via function pointers should use the BX instruction if the call is made in ARM mode: .code 32 mov lr, pc bx rX This code sequence will not work in Thumb mode however, since the mov instruction will not set the bottom bit of the lr register. Instead a branch-and-link to the _call_via_rX functions should be used instead: .code 16 bl _call_via_rX where rX is replaced by the name of the register containing the function address. * All externally visible functions which should be entered in Thumb mode must have the .thumb_func pseudo op specified just before their entry point. e.g.: .code 16 .global function .thumb_func function: ...start of function.... * All assembler files must be assembled with the switch -mthumb-interwork specified on the command line. (If the file is assembled by calling gcc it will automatically pass on the -mthumb-interwork switch to the assembler, provided that it was specified on the gcc command line in the first place.) 3. Support for old, non-interworking aware code. ================================================ If it is necessary to link together code produced by an older, non-interworking aware compiler, or code produced by the new compiler but without the -mthumb-interwork command line switch specified, then there are two command line switches that can be used to support this. The switch -mcaller-super-interworking will allow calls via function pointers in Thumb mode to work, regardless of whether the function pointer points to old, non-interworking aware code or not. Specifying this switch does produce slightly slower code however. Note: There is no switch to allow calls via function pointers in ARM mode to be handled specially. Calls via function pointers from interworking aware ARM code to non-interworking aware ARM code work without any special considerations by the compiler. Calls via function pointers from interworking aware ARM code to non-interworking aware Thumb code however will not work. (Actually under some circumstances they may work, but there are no guarantees). This is because only the new compiler is able to produce Thumb code, and this compiler already has a command line switch to produce interworking aware code. The switch -mcallee-super-interworking will allow non-interworking aware ARM or Thumb code to call Thumb functions, either directly or via function pointers. Specifying this switch does produce slightly larger, slower code however. Note: There is no switch to allow non-interworking aware ARM or Thumb code to call ARM functions. There is no need for any special handling of calls from non-interworking aware ARM code to interworking aware ARM functions, they just work normally. Calls from non-interworking aware Thumb functions to ARM code however, will not work. There is no option to support this, since it is always possible to recompile the Thumb code to be interworking aware. As an alternative to the command line switch -mcallee-super-interworking, which affects all externally visible functions in a file, it is possible to specify an attribute or declspec for individual functions, indicating that that particular function should support being called by non-interworking aware code. The function should be defined like this: int __attribute__((interfacearm)) function { ... body of function ... } or int __declspec(interfacearm) function { ... body of function ... } 4. Interworking support in dlltool ================================== It is possible to create DLLs containing mixed ARM and Thumb code. It is also possible to call Thumb code in a DLL from an ARM program and vice versa. It is even possible to call ARM DLLs that have been compiled without interworking support (say by an older version of the compiler), from Thumb programs and still have things work properly. A version of the `dlltool' program which supports the `--interwork' command line switch is needed, as well as the following special considerations when building programs and DLLs: *Use `-mthumb-interwork'* When compiling files for a DLL or a program the `-mthumb-interwork' command line switch should be specified if calling between ARM and Thumb code can happen. If a program is being compiled and the mode of the DLLs that it uses is not known, then it should be assumed that interworking might occur and the switch used. *Use `-m thumb'* If the exported functions from a DLL are all Thumb encoded then the `-m thumb' command line switch should be given to dlltool when building the stubs. This will make dlltool create Thumb encoded stubs, rather than its default of ARM encoded stubs. If the DLL consists of both exported Thumb functions and exported ARM functions then the `-m thumb' switch should not be used. Instead the Thumb functions in the DLL should be compiled with the `-mcallee-super-interworking' switch, or with the `interfacearm' attribute specified on their prototypes. In this way they will be given ARM encoded prologues, which will work with the ARM encoded stubs produced by dlltool. *Use `-mcaller-super-interworking'* If it is possible for Thumb functions in a DLL to call non-interworking aware code via a function pointer, then the Thumb code must be compiled with the `-mcaller-super-interworking' command line switch. This will force the function pointer calls to use the _interwork_call_via_rX stub functions which will correctly restore Thumb mode upon return from the called function. *Link with `libgcc.a'* When the dll is built it may have to be linked with the GCC library (`libgcc.a') in order to extract the _call_via_rX functions or the _interwork_call_via_rX functions. This represents a partial redundancy since the same functions *may* be present in the application itself, but since they only take up 372 bytes this should not be too much of a consideration. *Use `--support-old-code'* When linking a program with an old DLL which does not support interworking, the `--support-old-code' command line switch to the linker should be used. This causes the linker to generate special interworking stubs which can cope with old, non-interworking aware ARM code, at the cost of generating bulkier code. The linker will still generate a warning message along the lines of: "Warning: input file XXX does not support interworking, whereas YYY does." but this can now be ignored because the --support-old-code switch has been used. 5. How interworking support works ================================= Switching between the ARM and Thumb instruction sets is accomplished via the BX instruction which takes as an argument a register name. Control is transferred to the address held in this register (with the bottom bit masked out), and if the bottom bit is set, then Thumb instruction processing is enabled, otherwise ARM instruction processing is enabled. When the -mthumb-interwork command line switch is specified, gcc arranges for all functions to return to their caller by using the BX instruction. Thus provided that the return address has the bottom bit correctly initialized to indicate the instruction set of the caller, correct operation will ensue. When a function is called explicitly (rather than via a function pointer), the compiler generates a BL instruction to do this. The Thumb version of the BL instruction has the special property of setting the bottom bit of the LR register after it has stored the return address into it, so that a future BX instruction will correctly return the instruction after the BL instruction, in Thumb mode. The BL instruction does not change modes itself however, so if an ARM function is calling a Thumb function, or vice versa, it is necessary to generate some extra instructions to handle this. This is done in the linker when it is storing the address of the referenced function into the BL instruction. If the BL instruction is an ARM style BL instruction, but the referenced function is a Thumb function, then the linker automatically generates a calling stub that converts from ARM mode to Thumb mode, puts the address of this stub into the BL instruction, and puts the address of the referenced function into the stub. Similarly if the BL instruction is a Thumb BL instruction, and the referenced function is an ARM function, the linker generates a stub which converts from Thumb to ARM mode, puts the address of this stub into the BL instruction, and the address of the referenced function into the stub. This is why it is necessary to mark Thumb functions with the .thumb_func pseudo op when creating assembler files. This pseudo op allows the assembler to distinguish between ARM functions and Thumb functions. (The Thumb version of GCC automatically generates these pseudo ops for any Thumb functions that it generates). Calls via function pointers work differently. Whenever the address of a function is taken, the linker examines the type of the function being referenced. If the function is a Thumb function, then it sets the bottom bit of the address. Technically this makes the address incorrect, since it is now one byte into the start of the function, but this is never a problem because: a. with interworking enabled all calls via function pointer are done using the BX instruction and this ignores the bottom bit when computing where to go to. b. the linker will always set the bottom bit when the address of the function is taken, so it is never possible to take the address of the function in two different places and then compare them and find that they are not equal. As already mentioned any call via a function pointer will use the BX instruction (provided that interworking is enabled). The only problem with this is computing the return address for the return from the called function. For ARM code this can easily be done by the code sequence: mov lr, pc bx rX (where rX is the name of the register containing the function pointer). This code does not work for the Thumb instruction set, since the MOV instruction will not set the bottom bit of the LR register, so that when the called function returns, it will return in ARM mode not Thumb mode. Instead the compiler generates this sequence: bl _call_via_rX (again where rX is the name if the register containing the function pointer). The special call_via_rX functions look like this: .thumb_func _call_via_r0: bx r0 nop The BL instruction ensures that the correct return address is stored in the LR register and then the BX instruction jumps to the address stored in the function pointer, switch modes if necessary. 6. How caller-super-interworking support works ============================================== When the -mcaller-super-interworking command line switch is specified it changes the code produced by the Thumb compiler so that all calls via function pointers (including virtual function calls) now go via a different stub function. The code to call via a function pointer now looks like this: bl _interwork_call_via_r0 Note: The compiler does not insist that r0 be used to hold the function address. Any register will do, and there are a suite of stub functions, one for each possible register. The stub functions look like this: .code 16 .thumb_func _interwork_call_via_r0 bx pc nop .code 32 tst r0, #1 stmeqdb r13!, {lr} adreq lr, _arm_return bx r0 The stub first switches to ARM mode, since it is a lot easier to perform the necessary operations using ARM instructions. It then tests the bottom bit of the register containing the address of the function to be called. If this bottom bit is set then the function being called uses Thumb instructions and the BX instruction to come will switch back into Thumb mode before calling this function. (Note that it does not matter how this called function chooses to return to its caller, since the both the caller and callee are Thumb functions, and mode switching is necessary). If the function being called is an ARM mode function however, the stub pushes the return address (with its bottom bit set) onto the stack, replaces the return address with the address of the a piece of code called '_arm_return' and then performs a BX instruction to call the function. The '_arm_return' code looks like this: .code 32 _arm_return: ldmia r13!, {r12} bx r12 .code 16 It simply retrieves the return address from the stack, and then performs a BX operation to return to the caller and switch back into Thumb mode. 7. How callee-super-interworking support works ============================================== When -mcallee-super-interworking is specified on the command line the Thumb compiler behaves as if every externally visible function that it compiles has had the (interfacearm) attribute specified for it. What this attribute does is to put a special, ARM mode header onto the function which forces a switch into Thumb mode: without __attribute__((interfacearm)): .code 16 .thumb_func function: ... start of function ... with __attribute__((interfacearm)): .code 32 function: orr r12, pc, #1 bx r12 .code 16 .thumb_func .real_start_of_function: ... start of function ... Note that since the function now expects to be entered in ARM mode, it no longer has the .thumb_func pseudo op specified for its name. Instead the pseudo op is attached to a new label .real_start_of_ (where is the name of the function) which indicates the start of the Thumb code. This does have the interesting side effect in that if this function is now called from a Thumb mode piece of code outside of the current file, the linker will generate a calling stub to switch from Thumb mode into ARM mode, and then this is immediately overridden by the function's header which switches back into Thumb mode. In addition the (interfacearm) attribute also forces the function to return by using the BX instruction, even if has not been compiled with the -mthumb-interwork command line flag, so that the correct mode will be restored upon exit from the function. 8. Some examples ================ Given these two test files: int arm (void) { return 1 + thumb (); } int thumb (void) { return 2 + arm (); } The following pieces of assembler are produced by the ARM and Thumb version of GCC depending upon the command line options used: `-O2': .code 32 .code 16 .global _arm .global _thumb .thumb_func _arm: _thumb: mov ip, sp stmfd sp!, {fp, ip, lr, pc} push {lr} sub fp, ip, #4 bl _thumb bl _arm add r0, r0, #1 add r0, r0, #2 ldmea fp, {fp, sp, pc} pop {pc} Note how the functions return without using the BX instruction. If these files were assembled and linked together they would fail to work because they do not change mode when returning to their caller. `-O2 -mthumb-interwork': .code 32 .code 16 .global _arm .global _thumb .thumb_func _arm: _thumb: mov ip, sp stmfd sp!, {fp, ip, lr, pc} push {lr} sub fp, ip, #4 bl _thumb bl _arm add r0, r0, #1 add r0, r0, #2 ldmea fp, {fp, sp, lr} pop {r1} bx lr bx r1 Now the functions use BX to return their caller. They have grown by 4 and 2 bytes respectively, but they can now successfully be linked together and be expect to work. The linker will replace the destinations of the two BL instructions with the addresses of calling stubs which convert to the correct mode before jumping to the called function. `-O2 -mcallee-super-interworking': .code 32 .code 32 .global _arm .global _thumb _arm: _thumb: orr r12, pc, #1 bx r12 mov ip, sp .code 16 stmfd sp!, {fp, ip, lr, pc} push {lr} sub fp, ip, #4 bl _thumb bl _arm add r0, r0, #1 add r0, r0, #2 ldmea fp, {fp, sp, lr} pop {r1} bx lr bx r1 The thumb function now has an ARM encoded prologue, and it no longer has the `.thumb-func' pseudo op attached to it. The linker will not generate a calling stub for the call from arm() to thumb(), but it will still have to generate a stub for the call from thumb() to arm(). Also note how specifying `--mcallee-super-interworking' automatically implies `-mthumb-interworking'. 9. Some Function Pointer Examples ================================= Given this test file: int func (void) { return 1; } int call (int (* ptr)(void)) { return ptr (); } The following varying pieces of assembler are produced by the Thumb version of GCC depending upon the command line options used: `-O2': .code 16 .globl _func .thumb_func _func: mov r0, #1 bx lr .globl _call .thumb_func _call: push {lr} bl __call_via_r0 pop {pc} Note how the two functions have different exit sequences. In particular call() uses pop {pc} to return, which would not work if the caller was in ARM mode. func() however, uses the BX instruction, even though `-mthumb-interwork' has not been specified, as this is the most efficient way to exit a function when the return address is held in the link register. `-O2 -mthumb-interwork': .code 16 .globl _func .thumb_func _func: mov r0, #1 bx lr .globl _call .thumb_func _call: push {lr} bl __call_via_r0 pop {r1} bx r1 This time both functions return by using the BX instruction. This means that call() is now two bytes longer and several cycles slower than the previous version. `-O2 -mcaller-super-interworking': .code 16 .globl _func .thumb_func _func: mov r0, #1 bx lr .globl _call .thumb_func _call: push {lr} bl __interwork_call_via_r0 pop {pc} Very similar to the first (non-interworking) version, except that a different stub is used to call via the function pointer. This new stub will work even if the called function is not interworking aware, and tries to return to call() in ARM mode. Note that the assembly code for call() is still not interworking aware itself, and so should not be called from ARM code. `-O2 -mcallee-super-interworking': .code 32 .globl _func _func: orr r12, pc, #1 bx r12 .code 16 .globl .real_start_of_func .thumb_func .real_start_of_func: mov r0, #1 bx lr .code 32 .globl _call _call: orr r12, pc, #1 bx r12 .code 16 .globl .real_start_of_call .thumb_func .real_start_of_call: push {lr} bl __call_via_r0 pop {r1} bx r1 Now both functions have an ARM coded prologue, and both functions return by using the BX instruction. These functions are interworking aware therefore and can safely be called from ARM code. The code for the call() function is now 10 bytes longer than the original, non interworking aware version, an increase of over 200%. If a prototype for call() is added to the source code, and this prototype includes the `interfacearm' attribute: int __attribute__((interfacearm)) call (int (* ptr)(void)); then this code is produced (with only -O2 specified on the command line): .code 16 .globl _func .thumb_func _func: mov r0, #1 bx lr .globl _call .code 32 _call: orr r12, pc, #1 bx r12 .code 16 .globl .real_start_of_call .thumb_func .real_start_of_call: push {lr} bl __call_via_r0 pop {r1} bx r1 So now both call() and func() can be safely called via non-interworking aware ARM code. If, when such a file is assembled, the assembler detects the fact that call() is being called by another function in the same file, it will automatically adjust the target of the BL instruction to point to .real_start_of_call. In this way there is no need for the linker to generate a Thumb-to-ARM calling stub so that call can be entered in ARM mode. 10. How to use dlltool to build ARM/Thumb DLLs ============================================== Given a program (`prog.c') like this: extern int func_in_dll (void); int main (void) { return func_in_dll(); } And a DLL source file (`dll.c') like this: int func_in_dll (void) { return 1; } Here is how to build the DLL and the program for a purely ARM based environment: *Step One Build a `.def' file describing the DLL: ; example.def ; This file describes the contents of the DLL LIBRARY example HEAPSIZE 0x40000, 0x2000 EXPORTS func_in_dll 1 *Step Two Compile the DLL source code: arm-pe-gcc -O2 -c dll.c *Step Three Use `dlltool' to create an exports file and a library file: dlltool --def example.def --output-exp example.o --output-lib example.a *Step Four Link together the complete DLL: arm-pe-ld dll.o example.o -o example.dll *Step Five Compile the program's source code: arm-pe-gcc -O2 -c prog.c *Step Six Link together the program and the DLL's library file: arm-pe-gcc prog.o example.a -o prog If instead this was a Thumb DLL being called from an ARM program, the steps would look like this. (To save space only those steps that are different from the previous version are shown): *Step Two Compile the DLL source code (using the Thumb compiler): thumb-pe-gcc -O2 -c dll.c -mthumb-interwork *Step Three Build the exports and library files (and support interworking): dlltool -d example.def -z example.o -l example.a --interwork -m thumb *Step Five Compile the program's source code (and support interworking): arm-pe-gcc -O2 -c prog.c -mthumb-interwork If instead, the DLL was an old, ARM DLL which does not support interworking, and which cannot be rebuilt, then these steps would be used. *Step One Skip. If you do not have access to the sources of a DLL, there is no point in building a `.def' file for it. *Step Two Skip. With no DLL sources there is nothing to compile. *Step Three Skip. Without a `.def' file you cannot use dlltool to build an exports file or a library file. *Step Four Skip. Without a set of DLL object files you cannot build the DLL. Besides it has already been built for you by somebody else. *Step Five Compile the program's source code, this is the same as before: arm-pe-gcc -O2 -c prog.c *Step Six Link together the program and the DLL's library file, passing the `--support-old-code' option to the linker: arm-pe-gcc prog.o example.a -Wl,--support-old-code -o prog Ignore the warning message about the input file not supporting interworking as the --support-old-code switch has taken care if this.

Currently the backend interface has been implemented with GCC (known as gccgo) and with LLVM (known as GoLLVM). The frontend lexes and parses the input into an IR specific to this frontend known as gogo. It then runs a series of passes over the code. Finally it converts gogo to the backend IR. This is done via the interface described in backend.h. The backend must implement that interface. When used with GCC, the interface is implemented in gcc/go/go-gcc.cc. Source locations are represented using the interface described in go-linemap.h. The backend is expected to provide a header file go-location.h that defines a Location type. The frontend does not start by itself. It expects something to call go_create_gogo passing in a Backend and a Linemap, as well as other options. Then it expects something to call go_parse_input_files passing in the input files. Finally, a call to go_write_globals will cause all global definitions to be written out via the Backend interface. The backend is expected to provide the functions defined at the bottom of go-diagnostics.h: go_be_error_at, etc. These will be used for error messages. This compiler works, but the code is a work in progress. The frontend pays little attention to its memory usage and rarely frees any memory. The code could use a general cleanup which we have not had time to do.

In addition to supporting C++modules, this may also support LTO requirements and could also deal with generated #include files and feed the compiler with prepruned include paths and whatnot. (The system calls involved in include searches can be quite expensive on some build infrastructures.) * Client and Server objects * Direct connection for in-process use * Testing with Joust (that means nothing to you, doesn't it!) ## Problem Being Solved The origin is in C++20 modules: ``` import foo; ``` At that import, the compiler needs2 to load up the compiled serialization of module `foo`. Where is that file? Does it even exist? Unless the build system already knows the dependency graph, this might be a completely unknown module. Now, the build system knows how to build things, but it might not have complete information about the dependencies. The ultimate source of dependencies is the source code being compiled, and specifying the same thing in multiple places is a recipe for build skew. Hence, a protocol by which a compiler can query a build system. This was originally described in p1184r1:A Module Mapper. Along with a proof-of-concept hack in GNUmake, described in p1602:Make Me A Module. The current implementation has evolved and an update to p1184 will be forthcoming. ## Packet Encoding The protocol is turn-based. The compiler sends a block of one or more requests to the builder, then waits for a block of responses to all of those requests. If the builder needs to compile something to satisfy a request, there may be some time before the response. A builder may service multiple compilers concurrently, each as a separate connection. When multiple requests are in a block, the responses are also in a block, and in corresponding order. The responses must not be commenced eagerly -- they must wait until the incoming block has ended (as mentioned above, it is turn-based). To do otherwise risks deadlock, as there is no requirement for a sending end of the communication to listen for incoming responses (or new requests) until it has completed sending its current block. Every request has a response. Requests and responses are user-readable text. It is not intended as a transmission medium to send large binary objects (such as compiled modules). It is presumed the builder and the compiler share a file system, for that kind of thing.3 Messages characters are encoded in UTF8. Messages are a sequence of octets ending with a NEWLINE (0xa). The lines consist of a sequence of words, separated by WHITESPACE (0x20 or 0x9). Words themselves do not contain WHITESPACE. Lines consisting solely of WHITESPACE (or empty) are ignored. To encode a block of multiple messages, non-final messages end with a single word of SEMICOLON (0x3b), immediately before the NEWLINE. Thus a serial connection can determine whether a block is complete without decoding the messages. Words containing characters in the set [-+_/%.A-Za-z0-9] need not be quoted. Words containing characters outside that set should be quoted. A zero-length word may be achieved with `''` Quoted words begin and end with APOSTROPHE (x27). Within the quoted word, BACKSLASH (x5c) is used as an escape mechanism, with the following meanings: * \\n - NEWLINE (0xa) * \\t - TAB (0x9) * \\' - APOSTROPHE (') * \\\\ - BACKSLASH (\\) Characters in the range [0x00, 0x20) and 0x7f are encoded with one or two lowercase hex characters. Octets in the range [0x80,0xff) are UTF8 encodings of unicode characters outside the traditional ASCII set and passed as such. Decoding should be more relaxed. Unquoted words containing characters in the range [0x20,0xff] other than BACKSLASH or APOSTROPHE should be accepted. In a quoted sequence, `\` followed by one or two lower case hex characters decode to that octet. Further, words can be constructed from a mixture of abutted quoted and unquoted sequences. For instance `FOO' 'bar` would decode to the word `FOO bar`. Notice that the block continuation marker of `;` is not a valid encoding of the word `;`, which would be `';'`. It is recommended that words are separated by single SPACE characters. ## Messages The message descriptions use `$metavariable` examples. The request messages are specific to a particular action. The response messages are more generic, describing their value types, but not their meaning. Message consumers need to know the response to decode them. Notice the `Packet::GetRequest()` method records in response packets what the request being responded to was. Do not confuse this with the `Packet::GetCode ()` method. ### Responses The simplest response is a single: `OK` This indicates the request was successful. An error response is: `ERROR $message` The message is a human-readable string. It indicates failure of the request. Pathnames are encoded with: `PATHNAME $pathname` Boolean responses use: `BOOL `(`TRUE`|`FALSE`) ### Handshake Request The first message is a handshake: `HELLO $version $compiler $ident` The `$version` is a numeric value, currently `1`. `$compiler` identifies the compiler — builders may need to keep compiled modules from different compilers separate. `$ident` is an identifier the builder might use to identify the compilation it is communicating with. Responses are: `HELLO $version $builder [$flags]` A successful handshake. The communication is now connected and other messages may be exchanged. An ERROR response indicates an unsuccessful handshake. The communication remains unconnected. There is nothing restricting a handshake to its own message block. Of course, if the handshake fails, subsequent non-handshake messages in the block will fail (producing error responses). The `$flags` word, if present allows a server to control what requests might be given. See below. ### C++ Module Requests A set of requests are specific to C++ modules: #### Flags Several requests and one response have an optional `$flags` word. These are the `Cody::Flags` value pertaining to that request. If omitted the value 0 is implied. The following flags are available: * `0`, `None`: No flags. * `1<<0`, `NameOnly`: The request is for the name only, and not the CMI contents. The `NameOnly` flag may be provded in a handshake response, and indicates that the server is interested in requests only for their implied dependency information. It may be provided on a request to indicate that only the CMI name is required, not its contents (for instance, when preprocessing). Note that a compiler may still make `NameOnly` requests even if the server did not ask for such. #### Repository All relative CMI file names are relative to a repository. (There are usually no absolute CMI files). The repository may be determined with: `MODULE-REPO` A PATHNAME response is expected. The `$pathname` may be an empty word, which is equivalent to `.`. When the response is a relative pathname, it must be relative to the client's current working directory (which might be a process on a different host to the server). You may set the repository to `/`, if you with to use paths relative to the root directory. #### Exporting A compilation of a module interface, partition or header unit can inform the builder with: `MODULE-EXPORT $module [$flags]` This will result in a PATHNAME response naming the Compiled Module Interface pathname to write. The `MODULE-EXPORT` request does not indicate the module has been successfully compiled. At most one `MODULE-EXPORT` is to be made, and as the connection is for a single compilation, the builder may infer dependency relationships between the module being generated and import requests made. Named module names and header unit names are distinguished by making the latter unambiguously look like file names. Firstly, they must be fully resolved according to the compiler's usual include path. If that results in an absolute name file name (beginning with `/`, or certain other OS-specific sequences), all is well. Otherwise a relative file name must be prefixed by `./` to be distinguished from a similarly named named module. This prefixing must occur, even if the header-unit's name contains characters that cannot appear in a named module's name. It is expected that absolute header-unit names convert to relative CMI names, to keep all CMIs within the CMI repository. This means that steps must be taken to distinguish the CMIs for `/here` from `./here`, and this can be achieved by replacing the leading `./` directory with `,/`, which is visually similar but does not have the self-reference semantics of dot. Likewise, header-unit names containing `..` directories, can be remapped to `,,`. (When symlinks are involved `bob/dob/..` might not be `bob`, of course.) C++ header-unit semantics are such that there is no need to resolve multiple ways of spelling a particular header-unit to a unique CMI file. Successful compilation of an interface is indicated with a subsequent: `MODULE-COMPILED $module [$flags]` request. This indicates the CMI file has been written to disk, so that any other compilations waiting on it may proceed. Depending on compiler implementation, the CMI may be written before the compilation completes. A single OK response is expected. Compilation failure can be inferred by lack of a `MODULE-COMPILED` request. It is presumed the builder can determine this, as it is also responsible for launching and reaping the compiler invocations themselves. #### Importing Importation, including that of header-units, uses: `MODULE-IMPORT $module [$flags]` A PATHNAME response names the CMI file to be read. Should the builder have to invoke a compilation to produce the CMI, the response should be delayed until that occurs. If such a compilation fails, an error response should be provided to the requestor — which will then presumably fail in some manner. #### Include Translation Include translation can be determined with: `INCLUDE-TRANSLATE $header [$flags]` The header name, `$header`, is the fully resolved header name, in the above-mentioned unambiguous filename form. The response will either be a BOOL response indicating textual inclusion, or a PATHNAME response naming the CMI for such translation. The BOOL value is TRUE, if the header is known to be a textual header, and FALSE if nothing is known about it -- the latter might cause diagnostics about incomplete knowledge. ### GCC LTO Messages These set of requests are used for GCC LTO jobserver integration with GNU Make ## Building libCody Libcody is written in C++11. (It's a intended for compilers, so there'd be a bootstrapping problem if it used the latest and greatest.) ### Using configure and make. It supports the usual `configure`, `make`, `make check` & `make install` sequence. It does not support building in the source directory -- that just didn't drop out, and it's not how I build things (because, again, for compilers). Excitingly it uses my own `joust` test harness, so you'll need to build and install that somewhere, if you want the comfort of testing. The following configure options are available, in addition to the usual set: * `--enable-checking` Compile with assert-like checking. Defaults to on. * `--with-tooldir=DIR` Prepend `DIR` to `PATH` when building (`DIR` need not already include the trailing `/bin`, and the right things happen). Use this if you need to point to non-standard tools that you usually don't have in your path. This path is also used when the configure script searches for programs. * `--with-toolinc=DIR`, `--with-toollib=DIR`, include path and library path variants of `--with-tooldir`. If these are siblings of the tool bin directory, they'll be found automatically. * `--with-compiler=NAME` Specify a particular compiler to use. Usually what configure finds is sufficiently usable. * `--with-bugurl=URL` Override the bugreporting URL. Do this if you're providing libcody as part of a package that /you/ are supporting. * `--enable-maintainer-mode` Specify that rules to rebuild things like `configure` (with `autoconf`) should be enabled. When not enabled, you'll get a message if these appear out of date, but that can happen naturally after an update or clone as `git`, in common with other VCs, doesn't preserve the relative ordering of file modifications. You can use `make MAINTAINER=touch` to shut make up, if this occurs (or manually execute the `autoconf` and related commands). When building, you can override the default optimization flags with `CXXFLAGS=$flags`. I often build a debuggable library with `make CXXFLAGS=-g3`. The `Makefile` will also parallelize according to the number of CPUs, unless you specify explicitly with a `-j` option. This is a little clunky, as it's not possible to figure out inside the makefile whether the user provided `-j`. (Or at least I've not figured out how.) ### Using cmake and make #### In the clang/LLVM project The primary motivation for a cmake implementation is to allow building libcody "in tree" in clang/LLVM. In that case, a checkout of libcody can be placed (or symbolically linked) into clang/tools. This will configure and build the library along with other LLVM dependencies. *NOTE* This is not treated as an installable entity (it is present only for use by the project). *NOTE* The testing targets would not be appropriate in this configuration; it is expected that lit-based testing of the required functionality will be done by the code using the library. #### Stand-alone For use on platforms that don't support configure & make effectively, it is possible to use the cmake & make process in stand-alone mode (similar to the configure & make process above). An example use. ``` cmake -DCMAKE_INSTALL_PREFIX=/path/to/installation -DCMAKE_CXX_COMPILER=clang++ /path/to/libcody/source make make install ``` Supported flags (additions to the usual cmake ones). * `-DCODY_CHECKING=ON,OFF`: Compile with assert-like checking. (defaults ON) * `-DCODY_WITHEXCEPTIONS=ON,OFF`: Compile with C++ exceptions and RTTI enabled. (defaults OFF, to be compatible with GCC and LLVM). *TODO*: At present there is no support for `ctest` integration (this should be feasible, provided that `joust` is installed and can be discovered by `cmake`). ## API The library defines entities in the `::Cody` namespace. There are 4 user-visible classes: * `Packet`: Responses to requests are `Packets`. These have a code, indicating the response kind, and a payload. * `Client`: The compiler-end of a connection. Requests may be made and responses are returned. * `Server`: The builder-end of a connection. Requests may be waited for, and responses made. Builders that serve multiple concurrent connections and spawn compilations to resolve dependencies may need to derive from this class to provide response queuing. * `Resolver`: The processing engine of the builder side. User code is expected to derive from this class and provide virtual function overriders to affect the semantics of the resolver. In addition there are a number of helpers to setup connections. Logically the Client and the Server communicate via a sequential channel. The channel may be provided by: * two pipes, with different file descriptors for reading and writing at each end. * a socket, which will use the same file descriptor for reading and writing. the socket can be created in a number of ways, including Unix domain and IPv6 TCP, for which helpers are provided. * a direct, in-process, connection, using buffer swapping. The communication channel is presumed reliable. Refer to the (currently very sparse) doxygen-generated documentation for details of the API. ## Examples To create an in-process resolver, use the following boilerplate: ``` class MyResolver : Cody::Resolver { ... stuff here ... }; Cody::Client *MakeClient (char const *maybe_ident) { auto *r = new MyResolver (...); auto *s = new Cody::Server (r); auto *c = new Cody::Client (s); auto t = c->ConnectRequest ("ME", maybe_ident); if (t.GetCode () == Cody::Client::TC_CONNECT) ;// Yay! else if (t.GetCode () == Cody::Client::TC_ERROR) report_error (t.GetString ()); return c; } ``` For a remotely connecting client: ``` Cody::Client *MakeClient () { char const *err = nullptr; int fd = OpenInet6 (char const **err, name, port); if (fd < 0) { ... error... return nullptr;} auto *c = new Cody::Client (fd); auto t = c->ConnectRequest ("ME", maybe_ident); if (t.GetCode () == Cody::Client::TC_CONNECT) ;// Yay! else if (t.GetCode () == Cody::Client::TC_ERROR) report_error (t.GetString ()); return c; } ``` # Future Directions * Current Directory. There is no mechanism to check the builder and the compiler have the same working directory. Perhaps that should be addressed. * Include path canonization and/or header file lookup. This can be expensive, particularly with many `-I` options, due to the system calls. Perhaps using a common resource would be cheaper? * Generated header file lookup/construction. This is essentially the same problem as importing a module, and build systems are crap at dealing with this. * Link-time compilations. Another place the compiler would like to ask the build system to do things. * C++20 API entrypoints — std:string_view would be nice * Exception-safety audit. Exceptions are not used, but memory exhaustion could happen. And perhaps user's resolver code employs exceptions? 1: Or a small town in Wyoming 2: This describes one common implementation technique. The std itself doesn't require such serializations, but the ability to create them is kind of the point. Also, 'compiler' is used where we mean any consumer of a module, and 'build system' where we mean any producer of a module. 3: Even when the builder is managing a distributed set of compilations, the builder must have a mechanism to get source files to, and object files from, the compilations. That scheme can also transfer the CMI files. ======================================================================== * gcc libgo/README ======================================================================== See ../README. This is the runtime support library for the Go programming language. This library is intended for use with the Go frontend. This library should not be stripped when it is installed. Go code relies on being able to look up file/line information, which comes from the debugging info using the libbacktrace library. The library has only been tested on GNU/Linux using glibc, and on Solaris. It should not be difficult to port to other operating systems. Directories: go A copy of the Go library from http://golang.org/, with several changes for gccgo. runtime Runtime functions, written in C, which are called directly by the compiler or by the library.

If the copyright holder for your code has already completed the agreement in connection with another Google open source project, it does not need to be completed again. Debugging ========= This describes how to test libgo when built as part of gccgo. To test a specific package, cd to the libgo build directory (TARGET/libgo) and run `make PKG/check`. For example, `make bytes/check`. To see the exact commands that it runs, including how the compiler is invoked, run `make GOTESTFLAGS=--trace bytes/check`. This will display the commands if the test fails. If the test passes, the commands and other output will be visible in a file named check-testlog in a subdirectory with the name of the package being checked. In the case of bytes/check, this will create bytes/check-testlog. To leave the test program behind, run `make GOTESTFLAGS=--keep bytes/check`. That will leave a gotestNNNN/test directory in the libgo build directory. In that directory you can run `LD_LIBRARY_PATH=../../.libs ./a.out -test.short` to run the tests. You can run specific failing tests using a -test.run option. You can see the tests being run with the -test.v option. You can run the program under a debugger such as gdb. ======================================================================== * gcc libobjc/README ======================================================================== GNU Objective C notes ********************* This document is to explain what has been done, and a little about how specific features differ from other implementations. The runtime has been completely rewritten in gcc 2.4. The earlier runtime had several severe bugs and was rather incomplete. The compiler has had several new features added as well. This is not documentation for Objective C, it is usable to someone who knows Objective C from somewhere else. Runtime API functions ===================== The runtime is modeled after the NeXT Objective C runtime. That is, most functions have semantics as it is known from the NeXT. The names, however, have changed. All runtime API functions have names of lowercase letters and underscores as opposed to the `traditional' mixed case names. The runtime api functions are not documented as of now. Someone offered to write it, and did it, but we were not allowed to use it by his university (Very sad story). We have started writing the documentation over again. This will be announced in appropriate places when it becomes available. Protocols ========= Protocols are now fully supported. The semantics is exactly as on the NeXT. There is a flag to specify how protocols should be typechecked when adopted to classes. The normal typechecker requires that all methods in a given protocol must be implemented in the class that adopts it -- it is not enough to inherit them. The flag `-Wno-protocol' causes it to allow inherited methods, while `-Wprotocols' is the default which requires them defined. +load =========== This method, if defined, is called for each class and category implementation when the class is loaded into the runtime. This method is not inherited, and is thus not called for a subclass that doesn't define it itself. Thus, each +load method is called exactly once by the runtime. The runtime invocation of this method is thread safe. +initialize =========== This method, if defined, is called before any other instance or class methods of that particular class. For the GNU runtime, this method is not inherited, and is thus not called as initializer for a subclass that doesn't define it itself. Thus, each +initialize method is called exactly once by the runtime (or never if no methods of that particular class is never called). It is wise to guard against multiple invocations anyway to remain portable with the NeXT runtime. The runtime invocation of this method is thread safe. Passivation/Activation/Typedstreams =================================== This is supported in the style of NeXT TypedStream's. Consult the headerfile Typedstreams.h for api functions. I (Kresten) have rewritten it in Objective C, but this implementation is not part of 2.4, it is available from the GNU Objective C prerelease archive. There is one difference worth noting concerning objects stored with objc_write_object_reference (aka NXWriteObjectReference). When these are read back in, their object is not guaranteed to be available until the `-awake' method is called in the object that requests that object. To objc_read_object you must pass a pointer to an id, which is valid after exit from the function calling it (like e.g. an instance variable). In general, you should not use objects read in until the -awake method is called. Acknowledgements ================ The GNU Objective C team: Geoffrey Knauth (manager), Tom Wood (compiler) and Kresten Krab Thorup (runtime) would like to thank a some people for participating in the development of the present GNU Objective C. Paul Burchard and Andrew McCallum has been very helpful debugging the runtime. Eric Herring has been very helpful cleaning up after the documentation-copyright disaster and is now helping with the new documentation. Steve Naroff and Richard Stallman has been very helpful with implementation details in the compiler. Bug Reports =========== Please read the section `Submitting Bugreports' of the gcc manual before you submit any bugs. ======================================================================== * gcc zlib/README ======================================================================== This directory contains the zlib package, which is not part of GCC but shipped with GCC as convenience. ZLIB DATA COMPRESSION LIBRARY zlib 1.2.11 is a general purpose data compression library. All the code is thread safe. The data format used by the zlib library is described by RFCs (Request for Comments) 1950 to 1952 in the files http://tools.ietf.org/html/rfc1950 (zlib format), rfc1951 (deflate format) and rfc1952 (gzip format). All functions of the compression library are documented in the file zlib.h (volunteer to write man pages welcome, contact zlib@gzip.org). A usage example of the library is given in the file test/example.c which also tests that the library is working correctly. Another example is given in the file test/minigzip.c. The compression library itself is composed of all source files in the root directory. To compile all files and run the test program, follow the instructions given at the top of Makefile.in. In short "./configure; make test", and if that goes well, "make install" should work for most flavors of Unix. For Windows, use one of the special makefiles in win32/ or contrib/vstudio/ . For VMS, use make_vms.com. Questions about zlib should be sent to , or to Gilles Vollant for the Windows DLL version. The zlib home page is http://zlib.net/ . Before reporting a problem, please check this site to verify that you have the latest version of zlib; otherwise get the latest version and check whether the problem still exists or not. PLEASE read the zlib FAQ http://zlib.net/zlib_faq.html before asking for help. Mark Nelson wrote an article about zlib for the Jan. 1997 issue of Dr. Dobb's Journal; a copy of the article is available at http://marknelson.us/1997/01/01/zlib-engine/ . The changes made in version 1.2.11 are documented in the file ChangeLog. Unsupported third party contributions are provided in directory contrib/ . zlib is available in Java using the java.util.zip package, documented at http://java.sun.com/developer/technicalArticles/Programming/compression/ . A Perl interface to zlib written by Paul Marquess is available at CPAN (Comprehensive Perl Archive Network) sites, including http://search.cpan.org/~pmqs/IO-Compress-Zlib/ . A Python interface to zlib written by A.M. Kuchling is available in Python 1.5 and later versions, see http://docs.python.org/library/zlib.html . zlib is built into tcl: http://wiki.tcl.tk/4610 . An experimental package to read and write files in .zip format, written on top of zlib by Gilles Vollant , is available in the contrib/minizip directory of zlib. Notes for some targets: - For Windows DLL versions, please see win32/DLL_FAQ.txt - For 64-bit Irix, deflate.c must be compiled without any optimization. With -O, one libpng test fails. The test works in 32 bit mode (with the -n32 compiler flag). The compiler bug has been reported to SGI. - zlib doesn't work with gcc 2.6.3 on a DEC 3000/300LX under OSF/1 2.1 it works when compiled with cc. - On Digital Unix 4.0D (formely OSF/1) on AlphaServer, the cc option -std1 is necessary to get gzprintf working correctly. This is done by configure. - zlib doesn't work on HP-UX 9.05 with some versions of /bin/cc. It works with other compilers. Use "make test" to check your compiler. - gzdopen is not supported on RISCOS or BEOS. - For PalmOs, see http://palmzlib.sourceforge.net/ Acknowledgments: The deflate format used by zlib was defined by Phil Katz. The deflate and zlib specifications were written by L. Peter Deutsch. Thanks to all the people who reported problems and suggested various improvements in zlib; they are too numerous to cite here.

The original ZLib unit is Copyright (c) 1997,99 Borland Corp., and is based on zlib version 1.0.4. There are a series of bugs and security problems associated with that old zlib version, and we recommend the users to update their ZLib unit. Summary of modifications ======================== - Improved makefile, adapted to zlib version 1.2.1. - Some field types from TZStreamRec are changed from Integer to Longint, for consistency with the zlib.h header, and for 64-bit readiness. - The zlib_version constant is updated. - The new Z_RLE strategy has its corresponding symbolic constant. - The allocation and deallocation functions and function types (TAlloc, TFree, zlibAllocMem and zlibFreeMem) are now cdecl, and _malloc and _free are added as C RTL stubs. As a result, the original C sources of zlib can be compiled out of the box, and linked to the ZLib unit. Suggestions for improvements ============================ Currently, the ZLib unit provides only a limited wrapper around the zlib library, and much of the original zlib functionality is missing. Handling compressed file formats like ZIP/GZIP or PNG cannot be implemented without having this functionality. Applications that handle these formats are either using their own, duplicated code, or not using the ZLib unit at all. Here are a few suggestions: - Checksum class wrappers around adler32() and crc32(), similar to the Java classes that implement the java.util.zip.Checksum interface. - The ability to read and write raw deflate streams, without the zlib stream header and trailer. Raw deflate streams are used in the ZIP file format. - The ability to read and write gzip streams, used in the GZIP file format, and normally produced by the gzip program. - The ability to select a different compression strategy, useful to PNG and MNG image compression, and to multimedia compression in general. Besides the compression level TCompressionLevel = (clNone, clFastest, clDefault, clMax); which, in fact, could have used the 'z' prefix and avoided TColor-like symbols TCompressionLevel = (zcNone, zcFastest, zcDefault, zcMax); there could be a compression strategy TCompressionStrategy = (zsDefault, zsFiltered, zsHuffmanOnly, zsRle); - ZIP and GZIP stream handling via TStreams. -- Cosmin Truta ======================================================================== * gcc zlib/contrib/dotzlib/readme.txt ======================================================================== This directory contains a .Net wrapper class library for the ZLib1.dll The wrapper includes support for inflating/deflating memory buffers, .Net streaming wrappers for the gz streams part of zlib, and wrappers for the checksum parts of zlib. See DotZLib/UnitTests.cs for examples. Directory structure: -------------------- LICENSE_1_0.txt - License file. readme.txt - This file. DotZLib.chm - Class library documentation DotZLib.build - NAnt build file DotZLib.sln - Microsoft Visual Studio 2003 solution file DotZLib\*.cs - Source files for the class library Unit tests: ----------- The file DotZLib/UnitTests.cs contains unit tests for use with NUnit 2.1 or higher. To include unit tests in the build, define nunit before building. Build instructions: ------------------- 1. Using Visual Studio.Net 2003: Open DotZLib.sln in VS.Net and build from there. Output file (DotZLib.dll) will be found ./DotZLib/bin/release or ./DotZLib/bin/debug, depending on you are building the release or debug version of the library. Check DotZLib/UnitTests.cs for instructions on how to include unit tests in the build. 2. Using NAnt: Open a command prompt with access to the build environment and run nant in the same directory as the DotZLib.build file. You can define 2 properties on the nant command-line to control the build: debug={true|false} to toggle between release/debug builds (default=true). nunit={true|false} to include or esclude unit tests (default=true). Also the target clean will remove binaries. Output file (DotZLib.dll) will be found in either ./DotZLib/bin/release or ./DotZLib/bin/debug, depending on whether you are building the release or debug version of the library. Examples: nant -D:debug=false -D:nunit=false will build a release mode version of the library without unit tests. nant will build a debug version of the library with unit tests nant clean will remove all previously built files. --------------------------------- Copyright (c) Henrik Ravn 2004 Use, modification and distribution are subject to the Boost Software License, Version 1.0.

Directory listing ================= zlibd32.mak makefile for Borland C++ example.pas usage example of zlib zlibpas.pas the Pascal interface to zlib readme.txt this file Compatibility notes =================== - Although the name "zlib" would have been more normal for the zlibpas unit, this name is already taken by Borland's ZLib unit. This is somehow unfortunate, because that unit is not a genuine interface to the full-fledged zlib functionality, but a suite of class wrappers around zlib streams. Other essential features, such as checksums, are missing. It would have been more appropriate for that unit to have a name like "ZStreams", or something similar. - The C and zlib-supplied types int, uInt, long, uLong, etc. are translated directly into Pascal types of similar sizes (Integer, LongInt, etc.), to avoid namespace pollution. In particular, there is no conversion of unsigned int into a Pascal unsigned integer. The Word type is non-portable and has the same size (16 bits) both in a 16-bit and in a 32-bit environment, unlike Integer. Even if there is a 32-bit Cardinal type, there is no real need for unsigned int in zlib under a 32-bit environment. - Except for the callbacks, the zlib function interfaces are assuming the calling convention normally used in Pascal (__pascal for DOS and Windows16, __fastcall for Windows32). Since the cdecl keyword is used, the old Turbo Pascal does not work with this interface. - The gz* function interfaces are not translated, to avoid interfacing problems with the C runtime library. Besides, gzprintf(gzFile file, const char *format, ...) cannot be translated into Pascal. Legal issues ============ The zlibpas interface is: Copyright (C) 1995-2003 Jean-loup Gailly and Mark Adler.

All the code is thread safe. The data format used by the zlib library is described by RFCs (Request for Comments) 1950 to 1952 in the files http://www.ietf.org/rfc/rfc1950.txt (zlib format), rfc1951.txt (deflate format) and rfc1952.txt (gzip format). All functions of the compression library are documented in the file zlib.h (volunteer to write man pages welcome, contact zlib@gzip.org). Two compiled examples are distributed in this package, example and minigzip. The example_d and minigzip_d flavors validate that the zlib1.dll file is working correctly. Questions about zlib should be sent to . The zlib home page is http://zlib.net/ . Before reporting a problem, please check this site to verify that you have the latest version of zlib; otherwise get the latest version and check whether the problem still exists or not. PLEASE read DLL_FAQ.txt, and the the zlib FAQ http://zlib.net/zlib_faq.html before asking for help. Manifest: The package zlib-1.2.11-win32-x86.zip will contain the following files: README-WIN32.txt This document ChangeLog Changes since previous zlib packages DLL_FAQ.txt Frequently asked questions about zlib1.dll zlib.3.pdf Documentation of this library in Adobe Acrobat format example.exe A statically-bound example (using zlib.lib, not the dll) example.pdb Symbolic information for debugging example.exe example_d.exe A zlib1.dll bound example (using zdll.lib) example_d.pdb Symbolic information for debugging example_d.exe minigzip.exe A statically-bound test program (using zlib.lib, not the dll) minigzip.pdb Symbolic information for debugging minigzip.exe minigzip_d.exe A zlib1.dll bound test program (using zdll.lib) minigzip_d.pdb Symbolic information for debugging minigzip_d.exe zlib.h Install these files into the compilers' INCLUDE path to zconf.h compile programs which use zlib.lib or zdll.lib zdll.lib Install these files into the compilers' LIB path if linking zdll.exp a compiled program to the zlib1.dll binary zlib.lib Install these files into the compilers' LIB path to link zlib zlib.pdb into compiled programs, without zlib1.dll runtime dependency (zlib.pdb provides debugging info to the compile time linker) zlib1.dll Install this binary shared library into the system PATH, or the program's runtime directory (where the .exe resides) zlib1.pdb Install in the same directory as zlib1.dll, in order to debug an application crash using WinDbg or similar tools.

If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems. ======================================================================== * newlib-cygwin-50e2a63b04bdd018484605fbb954fd1bd5147fa0/newlib/README ======================================================================== README for newlib-3.2.0 release (mostly cribbed from the README in the gdb-4.13 release) This is `newlib', a simple ANSI C library, math library, and collection of board support packages. Prior to the 3.2.0 release, newlib supported both ANSI and K&R-style compilers. As of 3.2.0, K&R is no longer supported. The newlib and libgloss subdirectories are a collection of software from several sources, each with their own copyright and license. See the file COPYING.NEWLIB for details. The rest of the release tree is under either the GNU GPL or LGPL licenses. THIS SOFTWARE IS PROVIDED ``AS IS'' AND WITHOUT ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, WITHOUT LIMITATION, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. Unpacking and Installation -- quick overview ========================== When you unpack the newlib-3.2.0.tar.gz file, you'll find a directory called `newlib-3.2.0', which contains: COPYING config/ install-sh* mpw-configure COPYING.LIB config-ml.in libgloss/ mpw-install COPYING.NEWLIB config.guess* mkinstalldirs* newlib/ CYGNUS config.sub* move-if-change* symlink-tree* ChangeLog configure* mpw-README texinfo/ Makefile.in configure.in mpw-build.in README etc/ mpw-config.in To build NEWLIB, you must follow the instructions in the section entitled "Compiling NEWLIB". This will configure and build all the libraries and crt0 (if one exists). If `configure' can't determine your host system type, specify one as its argument, e.g., sun4 or sun4sol2. NEWLIB is most often used in cross environments. NOTE THAT YOU MUST HAVE ALREADY BUILT AND INSTALLED GCC and BINUTILS. More Documentation ================== Newlib documentation is available on the net via: http://sourceware.org/newlib/docs.html All the documentation for NEWLIB comes as part of the machine-readable distribution. The documentation is written in Texinfo format, which is a documentation system that uses a single source file to produce both on-line information and a printed manual. You can use one of the Info formatting commands to create the on-line version of the documentation and TeX (or `texi2roff') to typeset the printed version. If you want to format these Info files yourself, you need one of the Info formatting programs, such as `texinfo-format-buffer' or `makeinfo'. If you want to typeset and print copies of this manual, you need TeX, a program to print its DVI output files, and `texinfo.tex', the Texinfo definitions file. TeX is a typesetting program; it does not print files directly, but produces output files called DVI files. To print a typeset document, you need a program to print DVI files. If your system has TeX installed, chances are it has such a program. The precise command to use depends on your system; `lpr -d' is common; another (for PostScript devices) is `dvips'. The DVI print command may require a file name without any extension or a `.dvi' extension. TeX also requires a macro definitions file called `texinfo.tex'. This file tells TeX how to typeset a document written in Texinfo format. On its own, TeX cannot read, much less typeset a Texinfo file. `texinfo.tex' is distributed with NEWLIB and is located in the `newlib-VERSION-NUMBER/texinfo' directory. Compiling NEWLIB ================ To compile NEWLIB, you must build it in a directory separate from the source directory. If you want to run NEWLIB versions for several host or target machines, you need a different `newlib' compiled for each combination of host and target. `configure' is designed to make this easy by allowing you to generate each configuration in a separate subdirectory. If your `make' program handles the `VPATH' feature correctly (like GNU `make') running `make' in each of these directories builds the `newlib' libraries specified there. To build `newlib' in a specific directory, run `configure' with the `--srcdir' option to specify where to find the source. (You also need to specify a path to find `configure' itself from your working directory. If the path to `configure' would be the same as the argument to `--srcdir', you can leave out the `--srcdir' option; it will be assumed.) For example, with version 3.2.0, you can build NEWLIB in a separate directory for a Sun 4 cross m68k-aout environment like this: cd newlib-3.2.0 mkdir ../newlib-m68k-aout cd ../newlib-m68k-aout ../newlib-3.2.0/configure --host=sun4 --target=m68k-aout make When `configure' builds a configuration using a remote source directory, it creates a tree for the binaries with the same structure (and using the same names) as the tree under the source directory. In the example, you'd find the Sun 4 library `libiberty.a' in the directory `newlib-m68k-aout/libiberty', and NEWLIB itself in `newlib-m68k-aout/newlib'. When you run `make' to build a program or library, you must run it in a configured directory--whatever directory you were in when you called `configure' (or one of its subdirectories). The `Makefile' that `configure' generates in each source directory also runs recursively. If you type `make' in a source directory such as `newlib-3.2.0' (or in a separate configured directory configured with `--srcdir=PATH/newlib-3.2.0'), you will build all the required libraries. When you have multiple hosts or targets configured in separate directories, you can run `make' on them in parallel (for example, if they are NFS-mounted on each of the hosts); they will not interfere with each other. Specifying names for hosts and targets ====================================== The specifications used for hosts and targets in the `configure' script are based on a three-part naming scheme, but some short predefined aliases are also supported. The full naming scheme encodes three pieces of information in the following pattern: ARCHITECTURE-VENDOR-OS For example, you can use the alias `sun4' as a HOST argument or in a `--target=TARGET' option. The equivalent full name is `sparc-sun-sunos4'. The `configure' script accompanying NEWLIB does not provide any query facility to list all supported host and target names or aliases. `configure' calls the Bourne shell script `config.sub' to map abbreviations to full names; you can read the script, if you wish, or you can use it to test your guesses on abbreviations--for example: % sh config.sub sun4 sparc-sun-sunos4.1.1 % sh config.sub sun3 m68k-sun-sunos4.1.1 % sh config.sub decstation mips-dec-ultrix4.2 % sh config.sub hp300bsd m68k-hp-bsd % sh config.sub i386v i386-pc-sysv % sh config.sub i786v Invalid configuration `i786v': machine `i786v' not recognized The Build, Host and Target Concepts in newlib ============================================= The build, host and target concepts are defined for gcc as follows: build: the platform on which gcc is built. host: the platform on which gcc is run. target: the platform for which gcc generates code. Since newlib is a library, the target concept does not apply to it, and the build, host, and target options given to the top-level configure script must be changed for newlib's use. The build system shifts the options according to these correspondences: gcc's build platform has no equivalent in newlib. gcc's host platform is newlib's build platform. gcc's target platform is newlib's host platform. and as mentioned before, newlib has no concept of target. In summary: the --target=TARGET switch to the top-level configure script configures newlib's host platform. `configure' options =================== Here is a summary of the `configure' options and arguments that are most often useful for building NEWLIB. `configure' also has several other options not listed here. configure [--help] [--prefix=DIR] [--srcdir=PATH] [--target=TARGET] HOST You may introduce options with a single `-' rather than `--' if you prefer; but you may abbreviate option names if you use `--'. `--help' Display a quick summary of how to invoke `configure'. `--prefix=DIR' Configure the source to install programs and files in directory `DIR'. `--exec-prefix=DIR' Configure the source to install host-dependent files in directory `DIR'. `--srcdir=PATH' *Warning: using this option requires GNU `make', or another `make' that compatibly implements the `VPATH' feature. Use this option to make configurations in directories separate from the NEWLIB source directories. Among other things, you can use this to build (or maintain) several configurations simultaneously, in separate directories. `configure' writes configuration specific files in the current directory, but arranges for them to use the source in the directory PATH. `configure' will create directories under the working directory in parallel to the source directories below PATH. `--norecursion' Configure only the directory level where `configure' is executed; do not propagate configuration to subdirectories. `--target=TARGET' Configure NEWLIB for running on the specified TARGET. There is no convenient way to generate a list of all available targets. `HOST ...' Configure NEWLIB to be built using a cross compiler running on the specified HOST. There is no convenient way to generate a list of all available hosts. To fit diverse usage models, NEWLIB supports a group of configuration options so that library features can be turned on/off according to target system's requirements. One feature can be enabled by specifying `--enable-FEATURE=yes' or `--enable-FEATURE'. Or it can be disable by `--enable-FEATURE=no' or `--disable-FEATURE'. `--enable-newlib-io-pos-args' Enable printf-family positional arg support. Disabled by default, but some hosts enable it in configure.host. `--enable-newlib-io-c99-formats' Enable C99 support in IO functions like printf/scanf. Disabled by default, but some hosts enable it in configure.host. `--enable-newlib-register-fini' Enable finalization function registration using atexit. Disabled by default. `--enable-newlib-io-long-long' Enable long long type support in IO functions like printf/scanf. Disabled by default, but many hosts enable it in configure.host. `--enable-newlib-io-long-double' Enable long double type support in IO functions printf/scanf. Disabled by default, but some hosts enable it in configure.host. `--enable-newlib-mb' Enable multibyte support. Disabled by default. `--enable-newlib-iconv-encodings' Enable specific comma-separated list of bidirectional iconv encodings to be built-in. Disabled by default. `--enable-newlib-iconv-from-encodings' Enable specific comma-separated list of \"from\" iconv encodings to be built-in. Disabled by default. `--enable-newlib-iconv-to-encodings' Enable specific comma-separated list of \"to\" iconv encodings to be built-in. Disabled by default. `--enable-newlib-iconv-external-ccs' Enable capabilities to load external CCS files for iconv. Disabled by default. `--disable-newlib-atexit-dynamic-alloc' Disable dynamic allocation of atexit entries. Most hosts and targets have it enabled in configure.host. `--enable-newlib-global-atexit' Enable atexit data structure as global variable. By doing so it is move out of _reent structure, and can be garbage collected if atexit is not referenced. Disabled by default. `--enable-newlib-global-stdio-streams' Enable to move the stdio stream FILE objects out of struct _reent and make them global. The stdio stream pointers of struct _reent are initialized to point to the global stdio FILE stream objects. Disabled by default. `--enable-newlib-reent-small' Enable small reentrant struct support. Disabled by default. `--disable-newlib-fvwrite-in-streamio' NEWLIB implements the vector buffer mechanism to support stream IO buffering required by C standard. This feature is possibly unnecessary for embedded systems which won't change file buffering with functions like `setbuf' or `setvbuf'. The buffering mechanism still acts as default for STDIN/STDOUT/STDERR even if this option is specified. Enabled by default. `--disable-newlib-fseek-optimization' Disable fseek optimization. It can decrease code size of application calling `fseek`. Enabled by default. `--disable-newlib-wide-orient' C99 states that each stream has an orientation, wide or byte. This feature is possibly unnecessary for embedded systems which only do byte input/output operations on stream. It can decrease code size by disable the feature. Enabled by default. `--enable-newlib-nano-malloc' NEWLIB has two implementations of malloc family's functions, one in `mallocr.c' and the other one in `nano-mallocr.c'. This options enables the nano-malloc implementation, which is for small systems with very limited memory. Note that this implementation does not support `--enable-malloc-debugging' any more. Disabled by default. `--disable-newlib-unbuf-stream-opt' NEWLIB does optimization when `fprintf to write only unbuffered unix file'. It creates a temorary buffer to do the optimization that increases stack consumption by about `BUFSIZ' bytes. This option disables the optimization and saves size of text and stack. Enabled by default. `--enable-newlib-long-time_t' Define time_t to long. On platforms with a 32-bit long type, this gives raise to the year 2038 problem. The default type for time_t is a signed 64-bit integer on most systems. Disabled by default. `--enable-multilib' Build many library versions. Enabled by default. `--enable-target-optspace' Optimize for space. Disabled by default. `--enable-malloc-debugging' Indicate malloc debugging requested. Disabled by default. `--enable-newlib-multithread' Enable support for multiple threads. Enabled by default. `--enable-newlib-iconv' Enable iconv library support. Disabled by default. `--enable-newlib-elix-level' Supply desired elix library level (1-4). Please refer to HOWTO for more information about this option. Set to level 0 by default. `--disable-newlib-io-float' Disable printf/scanf family float support. Enabled by default. `--disable-newlib-supplied-syscalls' Disable newlib from supplying syscalls. Enabled by default. `--enable-lite-exit' Enable lite exit, a size-reduced implementation of exit that doesn't invoke clean-up functions such as _fini or global destructors. Disabled by default. `--enable-newlib-nano-formatted-io' This builds NEWLIB with a special implementation of formatted I/O functions, designed to lower the size of application on small systems with size constraint issues. This option does not affect wide-char formatted I/O functions. Some notes about the feature: 1) The non-wide-char formatted I/O functions only support the C89 standard. The only exception is the configuration option provides limited support for long double. Internally, the nano formatted I/O functions use double so accuracy is only guaranteed to double precision. 2) Floating-point support is split out of the formatted I/O code into weak functions which are not linked by default. Programs that need floating-point I/O support must explicitly request linking of one or both of the floating-point functions: _printf_float or _scanf_float. This can be done at link time using the -u option which can be passed to either gcc or ld. The -u option forces the link to resolve those function references. Floating-point format specifiers are recognized by default, but if the floating-point functions are not explicitly linked in, this may result in undefined behavior for programs that need floating-point I/O support. 3) Integer-only versions of the formatted I/O functions (the iprintf/ iscanf family) simply alias their regular counter-parts. The affected functions are: diprintf vdiprintf siprintf fiprintf iprintf sniprintf asiprintf asniprintf siscanf fiscanf iscanf viprintf vfiprintf vsiprintf vsniprintf vasiprintf vasniprintf viscanf vfiscanf vsiscanf _diprintf_r _vdiprintf_r _siprintf_r _fiprintf_r _iprintf_r _sniprintf_r _asiprintf_r _asniprintf_r _siscanf_r _fiscanf_r _iscanf_r _viprintf_r _vfiprintf_r _vsiprintf_r _asniprintf_r _vasiprintf_r _vasniprintf_r _viscanf_r _vfiscanf_r _vsiscanf_r 4) As mentioned, the option does not affect wide-char formatted I/O. The following configuration options are ignored for non-wide-char formatted I/O functions, and can be thought of as disabled. enable-newlib-io-pos-args enable-newlib-io-c99-formats enable-newlib-io-long-long enable-newlib-io-long-double enable-newlib-mb Additionally, "enable/disable-newlib-io-float" is supported in this specific implementation, one can use "disable-newlib-io-float" to further reduce code size. In this case, the floating-point specifiers will not be recognized or handled, and the -u option will not work either. 5) As a rule, no features from outside of C89 standard will be considered in this implementation. Disabled by default. Running the Testsuite ===================== To run newlib's testsuite, you'll need a site.exp in your home directory which points dejagnu to the proper baseboards directory and the proper exp file for your target. Before running make check-target-newlib, set the DEJAGNU environment variable to point to ~/site.exp. Here is a sample site.exp: # Make sure we look in the right place for the board description files. if ![info exists boards_dir] { set boards_dir {} } lappend boards_dir "your dejagnu/baseboards here" verbose "Global Config File: target_triplet is $target_triplet" 2 global target_list case "$target_triplet" in { { "mips-*elf*" } { set target_list "mips-sim" } default { set target_list { "unix" } } } mips-sim refers to an exp file in the baseboards directory. You'll need to add the other targets you're testing to the case statement. Now type make check-target-newlib in the top-level build directory to run the testsuite. Shared newlib ============= newlib uses libtool when it is being compiled natively (with --target=i[34567]86-pc-linux-gnu) on an i[34567]86-pc-linux-gnu host. This allows newlib to be compiled as a shared library. To configure newlib, do the following from your build directory: $(source_dir)/src/configure --with-newlib --prefix=$(install_dir) configure will recognize that host == target == i[34567]86-pc-linux-gnu, so it will tell newlib to compile itself using libtool. By default, libtool will build shared and static versions of newlib. To compile a program against shared newlib, do the following (where target_install_dir = $(install_dir)/i[34567]86-pc-linux-gnu): gcc -nostdlib $(target_install_dir)/lib/crt0.o progname.c -I $(target_install_dir)/include -L $(target_install_dir)/lib -lc -lm -lgcc To run the program, make sure that $(target_install_dir)/lib is listed in the LD_LIBRARY_PATH environment variable. To create a static binary linked against newlib, do the following: gcc -nostdlib -static $(target_install_dir)/lib/crt0.o progname.c -I $(target_install_dir)/include -L $(target_install_dir)/lib -lc -lm libtool can be instructed to produce only static libraries. To build newlib as a static library only, do the following from your build directory: $(source_dir)/src/configure --with-newlib --prefix=$(install_dir) --disable-shared Regenerating Configuration Files ================================ At times you will need to make changes to configure.in and Makefile.am files. This will mean that configure and Makefile.in files will need to be regenerated. At the top level of newlib is the file: acinclude.m4. This file contains the definition of the NEWLIB_CONFIGURE macro which is used by all configure.in files in newlib. You will notice that each directory in newlib containing a configure.in file also contains an aclocal.m4 file. This file is generated by issuing: aclocal -I${relative_path_to_toplevel_newlib_dir} -I${relative_path_to_toplevel_src_dir} The first relative directory is to access acinclude.m4. The second relative directory is to access libtool information in the top-level src directory. For example, to regenerate aclocal.m4 in newlib/libc/machine/arm: aclocal -I ../../.. -I ../../../.. Note that if the top level acinclude.m4 is altered, every aclocal.m4 file in newlib should be regenerated. If the aclocal.m4 file is regenerated due to a change in acinclude.m4 or if a configure.in file is modified, the corresponding configure file in the directory must be regenerated using autoconf. No parameters are necessary. In the previous example, we would issue: autoconf from the newlib/libc/machine/arm directory. If you have regenerated a configure file or if you have modified a Makefile.am file, you will need to regenerate the appropriate Makefile.in file(s). For newlib, automake is a bit trickier. First of all, all Makefile.in files in newlib (and libgloss) are generated using the --cygnus option of automake. Makefile.in files are generated from the nearest directory up the chain which contains a configure.in file. In most cases, this is the same directory containing configure.in, but there are exceptions. For example, the newlib/libc directory has a number of subdirectories that do not contain their own configure.in files (e.g. stdio). For these directories, you must issue the automake command from newlib/libc which is the nearest parent directory that contains a configure.in. When you issue the automake command, you specify the subdirectory for the Makefile.in you are regenerating. For example: automake --cygnus stdio/Makefile stdlib/Makefile Note how multiple Makefile.in files can be created in the same step. You would not specify machine/Makefile or sys/Makefile in the previous example because both of these subdirectories contain their own configure.in files. One would change to each of these subdirectories and in turn issue: automake --cygnus Makefile Let's say you create a new machine directory XXXX off of newlib/libc/machine. After creating a new configure.in and Makefile.am file, you would issue: aclocal -I ../../.. autoconf automake --cygnus Makefile from newlib/libc/machine/XXXX It is strongly advised that you use an adequate version of autotools. For this latest release, the following were used: autoconf 2.69, aclocal 1.13.4, and automake 1.13.4. Reporting Bugs ============== The correct address for reporting bugs found in NEWLIB is "newlib@sourceware.org". Please email all bug reports to that address. Please include the NEWLIB version number (e.g., newlib-3.2.0), and how you configured it (e.g., "sun4 host and m68k-aout target"). Since NEWLIB supports many different configurations, it is important that you be precise about this.

Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) year name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. , 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Library General Public License instead of this License. ======================================================================== * gcc COPYING.LIB, newlib-cygwin-50e2a63b04bdd018484605fbb954fd1bd5147fa0/COPYING.LIB ======================================================================== GNU LESSER GENERAL PUBLIC LICENSE Version 2.1, February 1999 Copyright (C) 1991, 1999 Free Software Foundation, Inc. 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. [This is the first released version of the Lesser GPL. It also counts as the successor of the GNU Library Public License, version 2, hence the version number 2.1.] Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This license, the Lesser General Public License, applies to some specially designated software packages--typically libraries--of the Free Software Foundation and other authors who decide to use it. You can use it too, but we suggest you first think carefully about whether this license or the ordinary General Public License is the better strategy to use in any particular case, based on the explanations below. When we speak of free software, we are referring to freedom of use, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish); that you receive source code or can get it if you want it; that you can change the software and use pieces of it in new free programs; and that you are informed that you can do these things. To protect your rights, we need to make restrictions that forbid distributors to deny you these rights or to ask you to surrender these rights. These restrictions translate to certain responsibilities for you if you distribute copies of the library or if you modify it. For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You must make sure that they, too, receive or can get the source code. If you link other code with the library, you must provide complete object files to the recipients, so that they can relink them with the library after making changes to the library and recompiling it. And you must show them these terms so they know their rights. We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you this license, which gives you legal permission to copy, distribute and/or modify the library. To protect each distributor, we want to make it very clear that there is no warranty for the free library. Also, if the library is modified by someone else and passed on, the recipients should know that what they have is not the original version, so that the original author's reputation will not be affected by problems that might be introduced by others. Finally, software patents pose a constant threat to the existence of any free program. We wish to make sure that a company cannot effectively restrict the users of a free program by obtaining a restrictive license from a patent holder. Therefore, we insist that any patent license obtained for a version of the library must be consistent with the full freedom of use specified in this license. Most GNU software, including some libraries, is covered by the ordinary GNU General Public License. This license, the GNU Lesser General Public License, applies to certain designated libraries, and is quite different from the ordinary General Public License. We use this license for certain libraries in order to permit linking those libraries into non-free programs. When a program is linked with a library, whether statically or using a shared library, the combination of the two is legally speaking a combined work, a derivative of the original library. The ordinary General Public License therefore permits such linking only if the entire combination fits its criteria of freedom. The Lesser General Public License permits more lax criteria for linking other code with the library. We call this license the "Lesser" General Public License because it does Less to protect the user's freedom than the ordinary General Public License. It also provides other free software developers Less of an advantage over competing non-free programs. These disadvantages are the reason we use the ordinary General Public License for many libraries. However, the Lesser license provides advantages in certain special circumstances. For example, on rare occasions, there may be a special need to encourage the widest possible use of a certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must be allowed to use the library. A more frequent case is that a free library does the same job as widely used non-free libraries. In this case, there is little to gain by limiting the free library to free software only, so we use the Lesser General Public License. In other cases, permission to use a particular library in non-free programs enables a greater number of people to use a large body of free software. For example, permission to use the GNU C Library in non-free programs enables many more people to use the whole GNU operating system, as well as its variant, the GNU/Linux operating system. Although the Lesser General Public License is Less protective of the users' freedom, it does ensure that the user of a program that is linked with the Library has the freedom and the wherewithal to run that program using a modified version of the Library. The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work based on the library" and a "work that uses the library". The former contains code derived from the library, whereas the latter must be combined with the library in order to run. GNU LESSER GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License Agreement applies to any software library or other program which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Lesser General Public License (also called "this License"). Each licensee is addressed as "you". A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables. The "Library", below, refers to any such software library or work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term "modification".) "Source code" for a work means the preferred form of the work for making modifications to it. For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library. Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does. 1. You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and distribute a copy of this License along with the Library. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) The modified work must itself be a software library. b) You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change. c) You must cause the whole of the work to be licensed at no charge to all third parties under the terms of this License. d) If a facility in the modified Library refers to a function or a table of data to be supplied by an application program that uses the facility, other than as an argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful. (For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply it, the square root function must still compute square roots.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Library, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Library, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Library. In addition, mere aggregation of another work not based on the Library with the Library (or with a work based on the Library) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices. Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy. This option is useful when you wish to copy part of the code of the Library into a program that is not a library. 4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange. If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code. 5. A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License. However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables. When a "work that uses the Library" uses material from a header file that is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law. If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of the Library will still fall under Section 6.) Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself. 6. As an exception to the Sections above, you may also combine or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications. You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things: a) Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.) b) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (1) uses at run time a copy of the library already present on the user's computer system, rather than copying library functions into the executable, and (2) will operate properly with a modified version of the library, if the user installs one, as long as the modified version is interface-compatible with the version that the work was made with. c) Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution. d) If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place. e) Verify that the user has already received a copy of these materials or that you have already sent this user a copy. For an executable, the required form of the "work that uses the Library" must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the materials to be distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute. 7. You may place library facilities that are a work based on the Library side-by-side in a single library together with other library facilities not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above. b) Give prominent notice with the combined library of the fact that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 9. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it. 10. Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties with this License. 11. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Library. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply, and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 12. If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Library under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 13. The Free Software Foundation may publish revised and/or new versions of the Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Library specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Library does not specify a license version number, you may choose any version ever published by the Free Software Foundation. 14. If you wish to incorporate parts of the Library into other free programs whose distribution conditions are incompatible with these, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Libraries If you develop a new library, and you want it to be of the greatest possible use to the public, we recommend making it free software that everyone can redistribute and change. You can do so by permitting redistribution under these terms (or, alternatively, under the terms of the ordinary General Public License). To apply these terms, attach the following notices to the library. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This library is free software; you can redistribute it and/or modify it under the terms of the GNU Lesser General Public License as published by the Free Software Foundation; either version 2.1 of the License, or (at your option) any later version. This library is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU Lesser General Public License for more details. You should have received a copy of the GNU Lesser General Public License along with this library; if not, write to the Free Software Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA Also add information on how to contact you by electronic and paper mail. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the library, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the library `Frob' (a library for tweaking knobs) written by James Random Hacker. , 1 April 1990 Ty Coon, President of Vice That's all there is to it! ======================================================================== * gcc COPYING.RUNTIME ======================================================================== GCC RUNTIME LIBRARY EXCEPTION Version 3.1, 31 March 2009 Copyright (C) 2009 Free Software Foundation, Inc. Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. This GCC Runtime Library Exception ("Exception") is an additional permission under section 7 of the GNU General Public License, version 3 ("GPLv3"). It applies to a given file (the "Runtime Library") that bears a notice placed by the copyright holder of the file stating that the file is governed by GPLv3 along with this Exception. When you use GCC to compile a program, GCC may combine portions of certain GCC header files and runtime libraries with the compiled program. The purpose of this Exception is to allow compilation of non-GPL (including proprietary) programs to use, in this way, the header files and runtime libraries covered by this Exception. 0. Definitions. A file is an "Independent Module" if it either requires the Runtime Library for execution after a Compilation Process, or makes use of an interface provided by the Runtime Library, but is not otherwise based on the Runtime Library. "GCC" means a version of the GNU Compiler Collection, with or without modifications, governed by version 3 (or a specified later version) of the GNU General Public License (GPL) with the option of using any subsequent versions published by the FSF. "GPL-compatible Software" is software whose conditions of propagation, modification and use would permit combination with GCC in accord with the license of GCC. "Target Code" refers to output from any compiler for a real or virtual target processor architecture, in executable form or suitable for input to an assembler, loader, linker and/or execution phase. Notwithstanding that, Target Code does not include data in any format that is used as a compiler intermediate representation, or used for producing a compiler intermediate representation. The "Compilation Process" transforms code entirely represented in non-intermediate languages designed for human-written code, and/or in Java Virtual Machine byte code, into Target Code. Thus, for example, use of source code generators and preprocessors need not be considered part of the Compilation Process, since the Compilation Process can be understood as starting with the output of the generators or preprocessors. A Compilation Process is "Eligible" if it is done using GCC, alone or with other GPL-compatible software, or if it is done without using any work based on GCC. For example, using non-GPL-compatible Software to optimize any GCC intermediate representations would not qualify as an Eligible Compilation Process. 1. Grant of Additional Permission. You have permission to propagate a work of Target Code formed by combining the Runtime Library with Independent Modules, even if such propagation would otherwise violate the terms of GPLv3, provided that all Target Code was generated by Eligible Compilation Processes. You may then convey such a combination under terms of your choice, consistent with the licensing of the Independent Modules. 2. No Weakening of GCC Copyleft. The availability of this Exception does not imply any general presumption that third-party software is unaffected by the copyleft requirements of the license of GCC. ======================================================================== * gcc COPYING3, gcc/COPYING3, include/COPYING3, newlib-cygwin-50e2a63b04bdd018484605fbb954fd1bd5147fa0/COPYING3, newlib-cygwin-50e2a63b04bdd018484605fbb954fd1bd5147fa0/include/COPYING3, newlib-cygwin-50e2a63b04bdd018484605fbb954fd1bd5147fa0/winsup/COPYING, nvptx-tools-5f6f343a302d620b0868edab376c00b15741e39e/COPYING3, nvptx-tools-5f6f343a302d620b0868edab376c00b15741e39e/include/COPYING3 ======================================================================== GNU GENERAL PUBLIC LICENSE Version 3, 29 June 2007 Copyright (C) 2007 Free Software Foundation, Inc. Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The GNU General Public License is a free, copyleft license for software and other kinds of works. The licenses for most software and other practical works are designed to take away your freedom to share and change the works. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change all versions of a program--to make sure it remains free software for all its users. We, the Free Software Foundation, use the GNU General Public License for most of our software; it applies also to any other work released this way by its authors. You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for them if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs, and that you know you can do these things. To protect your rights, we need to prevent others from denying you these rights or asking you to surrender the rights. Therefore, you have certain responsibilities if you distribute copies of the software, or if you modify it: responsibilities to respect the freedom of others. For example, if you distribute copies of such a program, whether gratis or for a fee, you must pass on to the recipients the same freedoms that you received. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. Developers that use the GNU GPL protect your rights with two steps: (1) assert copyright on the software, and (2) offer you this License giving you legal permission to copy, distribute and/or modify it. For the developers' and authors' protection, the GPL clearly explains that there is no warranty for this free software. For both users' and authors' sake, the GPL requires that modified versions be marked as changed, so that their problems will not be attributed erroneously to authors of previous versions. Some devices are designed to deny users access to install or run modified versions of the software inside them, although the manufacturer can do so. This is fundamentally incompatible with the aim of protecting users' freedom to change the software. The systematic pattern of such abuse occurs in the area of products for individuals to use, which is precisely where it is most unacceptable. Therefore, we have designed this version of the GPL to prohibit the practice for those products. If such problems arise substantially in other domains, we stand ready to extend this provision to those domains in future versions of the GPL, as needed to protect the freedom of users. Finally, every program is threatened constantly by software patents. States should not allow patents to restrict development and use of software on general-purpose computers, but in those that do, we wish to avoid the special danger that patents applied to a free program could make it effectively proprietary. To prevent this, the GPL assures that patents cannot be used to render the program non-free. The precise terms and conditions for copying, distribution and modification follow. TERMS AND CONDITIONS 0. Definitions. "This License" refers to version 3 of the GNU General Public License. "Copyright" also means copyright-like laws that apply to other kinds of works, such as semiconductor masks. "The Program" refers to any copyrightable work licensed under this License. Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals or organizations. To "modify" a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than the making of an exact copy. The resulting work is called a "modified version" of the earlier work or a work "based on" the earlier work. A "covered work" means either the unmodified Program or a work based on the Program. To "propagate" a work means to do anything with it that, without permission, would make you directly or secondarily liable for infringement under applicable copyright law, except executing it on a computer or modifying a private copy. Propagation includes copying, distribution (with or without modification), making available to the public, and in some countries other activities as well. To "convey" a work means any kind of propagation that enables other parties to make or receive copies. Mere interaction with a user through a computer network, with no transfer of a copy, is not conveying. An interactive user interface displays "Appropriate Legal Notices" to the extent that it includes a convenient and prominently visible feature that (1) displays an appropriate copyright notice, and (2) tells the user that there is no warranty for the work (except to the extent that warranties are provided), that licensees may convey the work under this License, and how to view a copy of this License. If the interface presents a list of user commands or options, such as a menu, a prominent item in the list meets this criterion. 1. Source Code. The "source code" for a work means the preferred form of the work for making modifications to it. "Object code" means any non-source form of a work. A "Standard Interface" means an interface that either is an official standard defined by a recognized standards body, or, in the case of interfaces specified for a particular programming language, one that is widely used among developers working in that language. The "System Libraries" of an executable work include anything, other than the work as a whole, that (a) is included in the normal form of packaging a Major Component, but which is not part of that Major Component, and (b) serves only to enable use of the work with that Major Component, or to implement a Standard Interface for which an implementation is available to the public in source code form. A "Major Component", in this context, means a major essential component (kernel, window system, and so on) of the specific operating system (if any) on which the executable work runs, or a compiler used to produce the work, or an object code interpreter used to run it. The "Corresponding Source" for a work in object code form means all the source code needed to generate, install, and (for an executable work) run the object code and to modify the work, including scripts to control those activities. However, it does not include the work's System Libraries, or general-purpose tools or generally available free programs which are used unmodified in performing those activities but which are not part of the work. For example, Corresponding Source includes interface definition files associated with source files for the work, and the source code for shared libraries and dynamically linked subprograms that the work is specifically designed to require, such as by intimate data communication or control flow between those subprograms and other parts of the work. The Corresponding Source need not include anything that users can regenerate automatically from other parts of the Corresponding Source. The Corresponding Source for a work in source code form is that same work. 2. Basic Permissions. All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met. This License explicitly affirms your unlimited permission to run the unmodified Program. The output from running a covered work is covered by this License only if the output, given its content, constitutes a covered work. This License acknowledges your rights of fair use or other equivalent, as provided by copyright law. You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force. You may convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities for running those works, provided that you comply with the terms of this License in conveying all material for which you do not control copyright. Those thus making or running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any copies of your copyrighted material outside their relationship with you. Conveying under any other circumstances is permitted solely under the conditions stated below. Sublicensing is not allowed; section 10 makes it unnecessary. 3. Protecting Users' Legal Rights From Anti-Circumvention Law. No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention of such measures. When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification of the work as a means of enforcing, against the work's users, your or third parties' legal rights to forbid circumvention of technological measures. 4. Conveying Verbatim Copies. You may convey verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program. You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee. 5. Conveying Modified Source Versions. You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions: a) The work must carry prominent notices stating that you modified it, and giving a relevant date. b) The work must carry prominent notices stating that it is released under this License and any conditions added under section 7. This requirement modifies the requirement in section 4 to "keep intact all notices". c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy. This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged. This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it. d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so. A compilation of a covered work with other separate and independent works, which are not by their nature extensions of the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an "aggregate" if the compilation and its resulting copyright are not used to limit the access or legal rights of the compilation's users beyond what the individual works permit. Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the aggregate. 6. Conveying Non-Source Forms. You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-readable Corresponding Source under the terms of this License, in one of these ways: a) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by the Corresponding Source fixed on a durable physical medium customarily used for software interchange. b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code either (1) a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network server at no charge. c) Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source. This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b. d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source in the same way through the same place at no further charge. You need not require recipients to copy the Corresponding Source along with the object code. If the place to copy the object code is a network server, the Corresponding Source may be on a different server (operated by you or a third party) that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the Corresponding Source. Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements. e) Convey the object code using peer-to-peer transmission, provided you inform other peers where the object code and Corresponding Source of the work are being offered to the general public at no charge under subsection 6d. A separable portion of the object code, whose source code is excluded from the Corresponding Source as a System Library, need not be included in conveying the object code work. A "User Product" is either (1) a "consumer product", which means any tangible personal property which is normally used for personal, family, or household purposes, or (2) anything designed or sold for incorporation into a dwelling. In determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage. For a particular product received by a particular user, "normally used" refers to a typical or common use of that class of product, regardless of the status of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product. A product is a consumer product regardless of whether the product has substantial commercial, industrial or non-consumer uses, unless such uses represent the only significant mode of use of the product. "Installation Information" for a User Product means any methods, procedures, authorization keys, or other information required to install and execute modified versions of a covered work in that User Product from a modified version of its Corresponding Source. The information must suffice to ensure that the continued functioning of the modified object code is in no case prevented or interfered with solely because modification has been made. If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveying occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding Source conveyed under this section must be accompanied by the Installation Information. But this requirement does not apply if neither you nor any third party retains the ability to install modified object code on the User Product (for example, the work has been installed in ROM). The requirement to provide Installation Information does not include a requirement to continue to provide support service, warranty, or updates for a work that has been modified or installed by the recipient, or for the User Product in which it has been modified or installed. Access to a network may be denied when the modification itself materially and adversely affects the operation of the network or violates the rules and protocols for communication across the network. Corresponding Source conveyed, and Installation Information provided, in accord with this section must be in a format that is publicly documented (and with an implementation available to the public in source code form), and must require no special password or key for unpacking, reading or copying. 7. Additional Terms. "Additional permissions" are terms that supplement the terms of this License by making exceptions from one or more of its conditions. Additional permissions that are applicable to the entire Program shall be treated as though they were included in this License, to the extent that they are valid under applicable law. If additional permissions apply only to part of the Program, that part may be used separately under those permissions, but the entire Program remains governed by this License without regard to the additional permissions. When you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, or from any part of it. (Additional permissions may be written to require their own removal in certain cases when you modify the work.) You may place additional permissions on material, added by you to a covered work, for which you have or can give appropriate copyright permission. Notwithstanding any other provision of this License, for material you add to a covered work, you may (if authorized by the copyright holders of that material) supplement the terms of this License with terms: a) Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; or b) Requiring preservation of specified reasonable legal notices or author attributions in that material or in the Appropriate Legal Notices displayed by works containing it; or c) Prohibiting misrepresentation of the origin of that material, or requiring that modified versions of such material be marked in reasonable ways as different from the original version; or d) Limiting the use for publicity purposes of names of licensors or authors of the material; or e) Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks; or f) Requiring indemnification of licensors and authors of that material by anyone who conveys the material (or modified versions of it) with contractual assumptions of liability to the recipient, for any liability that these contractual assumptions directly impose on those licensors and authors. All other non-permissive additional terms are considered "further restrictions" within the meaning of section 10. If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may remove that term. If a license document contains a further restriction but permits relicensing or conveying under this License, you may add to a covered work material governed by the terms of that license document, provided that the further restriction does not survive such relicensing or conveying. If you add terms to a covered work in accord with this section, you must place, in the relevant source files, a statement of the additional terms that apply to those files, or a notice indicating where to find the applicable terms. Additional terms, permissive or non-permissive, may be stated in the form of a separately written license, or stated as exceptions; the above requirements apply either way. 8. Termination. You may not propagate or modify a covered work except as expressly provided under this License. Any attempt otherwise to propagate or modify it is void, and will automatically terminate your rights under this License (including any patent licenses granted under the third paragraph of section 11). However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation. Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice. Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, you do not qualify to receive new licenses for the same material under section 10. 9. Acceptance Not Required for Having Copies. You are not required to accept this License in order to receive or run a copy of the Program. Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance. However, nothing other than this License grants you permission to propagate or modify any covered work. These actions infringe copyright if you do not accept this License. Therefore, by modifying or propagating a covered work, you indicate your acceptance of this License to do so. 10. Automatic Licensing of Downstream Recipients. Each time you convey a covered work, the recipient automatically receives a license from the original licensors, to run, modify and propagate that work, subject to this License. You are not responsible for enforcing compliance by third parties with this License. An "entity transaction" is a transaction transferring control of an organization, or substantially all assets of one, or subdividing an organization, or merging organizations. If propagation of a covered work results from an entity transaction, each party to that transaction who receives a copy of the work also receives whatever licenses to the work the party's predecessor in interest had or could give under the previous paragraph, plus a right to possession of the Corresponding Source of the work from the predecessor in interest, if the predecessor has it or can get it with reasonable efforts. You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License. For example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is infringed by making, using, selling, offering for sale, or importing the Program or any portion of it. 11. Patents. A "contributor" is a copyright holder who authorizes use under this License of the Program or a work on which the Program is based. The work thus licensed is called the contributor's "contributor version". A contributor's "essential patent claims" are all patent claims owned or controlled by the contributor, whether already acquired or hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or selling its contributor version, but do not include claims that would be infringed only as a consequence of further modification of the contributor version. For purposes of this definition, "control" includes the right to grant patent sublicenses in a manner consistent with the requirements of this License. Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor's essential patent claims, to make, use, sell, offer for sale, import and otherwise run, modify and propagate the contents of its contributor version. In the following three paragraphs, a "patent license" is any express agreement or commitment, however denominated, not to enforce a patent (such as an express permission to practice a patent or covenant not to sue for patent infringement). To "grant" such a patent license to a party means to make such an agreement or commitment not to enforce a patent against the party. If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other readily accessible means, then you must either (1) cause the Corresponding Source to be so available, or (2) arrange to deprive yourself of the benefit of the patent license for this particular work, or (3) arrange, in a manner consistent with the requirements of this License, to extend the patent license to downstream recipients. "Knowingly relying" means you have actual knowledge that, but for the patent license, your conveying the covered work in a country, or your recipient's use of the covered work in a country, would infringe one or more identifiable patents in that country that you have reason to believe are valid. If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use, propagate, modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended to all recipients of the covered work and works based on it. A patent license is "discriminatory" if it does not include within the scope of its coverage, prohibits the exercise of, or is conditioned on the non-exercise of one or more of the rights that are specifically granted under this License. You may not convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license (a) in connection with copies of the covered work conveyed by you (or copies made from those copies), or (b) primarily for and in connection with specific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28 March 2007. Nothing in this License shall be construed as excluding or limiting any implied license or other defenses to infringement that may otherwise be available to you under applicable patent law. 12. No Surrender of Others' Freedom. If conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot convey a covered work so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not convey it at all. For example, if you agree to terms that obligate you to collect a royalty for further conveying from those to whom you convey the Program, the only way you could satisfy both those terms and this License would be to refrain entirely from conveying the Program. 13. Use with the GNU Affero General Public License. Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU Affero General Public License into a single combined work, and to convey the resulting work. The terms of this License will continue to apply to the part which is the covered work, but the special requirements of the GNU Affero General Public License, section 13, concerning interaction through a network will apply to the combination as such. 14. Revised Versions of this License. The Free Software Foundation may publish revised and/or new versions of the GNU General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies that a certain numbered version of the GNU General Public License "or any later version" applies to it, you have the option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of the GNU General Public License, you may choose any version ever published by the Free Software Foundation. If the Program specifies that a proxy can decide which future versions of the GNU General Public License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Program. Later license versions may give you additional or different permissions. However, no additional obligations are imposed on any author or copyright holder as a result of your choosing to follow a later version. 15. Disclaimer of Warranty. THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 16. Limitation of Liability. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. 17. Interpretation of Sections 15 and 16. If the disclaimer of warranty and limitation of liability provided above cannot be given local legal effect according to their terms, reviewing courts shall apply local law that most closely approximates an absolute waiver of all civil liability in connection with the Program, unless a warranty or assumption of liability accompanies a copy of the Program in return for a fee. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively state the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This program is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program. If not, see . Also add information on how to contact you by electronic and paper mail. If the program does terminal interaction, make it output a short notice like this when it starts in an interactive mode: Copyright (C) This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, your program's commands might be different; for a GUI interface, you would use an "about box". You should also get your employer (if you work as a programmer) or school, if any, to sign a "copyright disclaimer" for the program, if necessary. For more information on this, and how to apply and follow the GNU GPL, see . The GNU General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Lesser General Public License instead of this License. But first, please read . ======================================================================== * gcc COPYING3.LIB, gcc/COPYING3.LIB, newlib-cygwin-50e2a63b04bdd018484605fbb954fd1bd5147fa0/COPYING3.LIB ======================================================================== GNU LESSER GENERAL PUBLIC LICENSE Version 3, 29 June 2007 Copyright (C) 2007 Free Software Foundation, Inc. Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. This version of the GNU Lesser General Public License incorporates the terms and conditions of version 3 of the GNU General Public License, supplemented by the additional permissions listed below. 0. Additional Definitions. As used herein, "this License" refers to version 3 of the GNU Lesser General Public License, and the "GNU GPL" refers to version 3 of the GNU General Public License. "The Library" refers to a covered work governed by this License, other than an Application or a Combined Work as defined below. An "Application" is any work that makes use of an interface provided by the Library, but which is not otherwise based on the Library. Defining a subclass of a class defined by the Library is deemed a mode of using an interface provided by the Library. A "Combined Work" is a work produced by combining or linking an Application with the Library. The particular version of the Library with which the Combined Work was made is also called the "Linked Version". The "Minimal Corresponding Source" for a Combined Work means the Corresponding Source for the Combined Work, excluding any source code for portions of the Combined Work that, considered in isolation, are based on the Application, and not on the Linked Version. The "Corresponding Application Code" for a Combined Work means the object code and/or source code for the Application, including any data and utility programs needed for reproducing the Combined Work from the Application, but excluding the System Libraries of the Combined Work. 1. Exception to Section 3 of the GNU GPL. You may convey a covered work under sections 3 and 4 of this License without being bound by section 3 of the GNU GPL. 2. Conveying Modified Versions. If you modify a copy of the Library, and, in your modifications, a facility refers to a function or data to be supplied by an Application that uses the facility (other than as an argument passed when the facility is invoked), then you may convey a copy of the modified version: a) under this License, provided that you make a good faith effort to ensure that, in the event an Application does not supply the function or data, the facility still operates, and performs whatever part of its purpose remains meaningful, or b) under the GNU GPL, with none of the additional permissions of this License applicable to that copy. 3. Object Code Incorporating Material from Library Header Files. The object code form of an Application may incorporate material from a header file that is part of the Library. You may convey such object code under terms of your choice, provided that, if the incorporated material is not limited to numerical parameters, data structure layouts and accessors, or small macros, inline functions and templates (ten or fewer lines in length), you do both of the following: a) Give prominent notice with each copy of the object code that the Library is used in it and that the Library and its use are covered by this License. b) Accompany the object code with a copy of the GNU GPL and this license document. 4. Combined Works. You may convey a Combined Work under terms of your choice that, taken together, effectively do not restrict modification of the portions of the Library contained in the Combined Work and reverse engineering for debugging such modifications, if you also do each of the following: a) Give prominent notice with each copy of the Combined Work that the Library is used in it and that the Library and its use are covered by this License. b) Accompany the Combined Work with a copy of the GNU GPL and this license document. c) For a Combined Work that displays copyright notices during execution, include the copyright notice for the Library among these notices, as well as a reference directing the user to the copies of the GNU GPL and this license document. d) Do one of the following: 0) Convey the Minimal Corresponding Source under the terms of this License, and the Corresponding Application Code in a form suitable for, and under terms that permit, the user to recombine or relink the Application with a modified version of the Linked Version to produce a modified Combined Work, in the manner specified by section 6 of the GNU GPL for conveying Corresponding Source. 1) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (a) uses at run time a copy of the Library already present on the user's computer system, and (b) will operate properly with a modified version of the Library that is interface-compatible with the Linked Version. e) Provide Installation Information, but only if you would otherwise be required to provide such information under section 6 of the GNU GPL, and only to the extent that such information is necessary to install and execute a modified version of the Combined Work produced by recombining or relinking the Application with a modified version of the Linked Version. (If you use option 4d0, the Installation Information must accompany the Minimal Corresponding Source and Corresponding Application Code. If you use option 4d1, you must provide the Installation Information in the manner specified by section 6 of the GNU GPL for conveying Corresponding Source.) 5. Combined Libraries. You may place library facilities that are a work based on the Library side by side in a single library together with other library facilities that are not Applications and are not covered by this License, and convey such a combined library under terms of your choice, if you do both of the following: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities, conveyed under the terms of this License. b) Give prominent notice with the combined library that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 6. Revised Versions of the GNU Lesser General Public License. The Free Software Foundation may publish revised and/or new versions of the GNU Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Library as you received it specifies that a certain numbered version of the GNU Lesser General Public License "or any later version" applies to it, you have the option of following the terms and conditions either of that published version or of any later version published by the Free Software Foundation. If the Library as you received it does not specify a version number of the GNU Lesser General Public License, you may choose any version of the GNU Lesser General Public License ever published by the Free Software Foundation. If the Library as you received it specifies that a proxy can decide whether future versions of the GNU Lesser General Public License shall apply, that proxy's public statement of acceptance of any version is permanent authorization for you to choose that version for the Library. ======================================================================== * gcc gcc/COPYING.LIB, libiberty/COPYING.LIB, libquadmath/COPYING.LIB, nvptx-tools-5f6f343a302d620b0868edab376c00b15741e39e/libiberty/COPYING.LIB ======================================================================== GNU LESSER GENERAL PUBLIC LICENSE Version 2.1, February 1999 Copyright (C) 1991, 1999 Free Software Foundation, Inc. 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. [This is the first released version of the Lesser GPL. It also counts as the successor of the GNU Library Public License, version 2, hence the version number 2.1.] Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This license, the Lesser General Public License, applies to some specially designated software packages--typically libraries--of the Free Software Foundation and other authors who decide to use it. You can use it too, but we suggest you first think carefully about whether this license or the ordinary General Public License is the better strategy to use in any particular case, based on the explanations below. When we speak of free software, we are referring to freedom of use, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish); that you receive source code or can get it if you want it; that you can change the software and use pieces of it in new free programs; and that you are informed that you can do these things. To protect your rights, we need to make restrictions that forbid distributors to deny you these rights or to ask you to surrender these rights. These restrictions translate to certain responsibilities for you if you distribute copies of the library or if you modify it. For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You must make sure that they, too, receive or can get the source code. If you link other code with the library, you must provide complete object files to the recipients, so that they can relink them with the library after making changes to the library and recompiling it. And you must show them these terms so they know their rights. We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you this license, which gives you legal permission to copy, distribute and/or modify the library. To protect each distributor, we want to make it very clear that there is no warranty for the free library. Also, if the library is modified by someone else and passed on, the recipients should know that what they have is not the original version, so that the original author's reputation will not be affected by problems that might be introduced by others. Finally, software patents pose a constant threat to the existence of any free program. We wish to make sure that a company cannot effectively restrict the users of a free program by obtaining a restrictive license from a patent holder. Therefore, we insist that any patent license obtained for a version of the library must be consistent with the full freedom of use specified in this license. Most GNU software, including some libraries, is covered by the ordinary GNU General Public License. This license, the GNU Lesser General Public License, applies to certain designated libraries, and is quite different from the ordinary General Public License. We use this license for certain libraries in order to permit linking those libraries into non-free programs. When a program is linked with a library, whether statically or using a shared library, the combination of the two is legally speaking a combined work, a derivative of the original library. The ordinary General Public License therefore permits such linking only if the entire combination fits its criteria of freedom. The Lesser General Public License permits more lax criteria for linking other code with the library. We call this license the "Lesser" General Public License because it does Less to protect the user's freedom than the ordinary General Public License. It also provides other free software developers Less of an advantage over competing non-free programs. These disadvantages are the reason we use the ordinary General Public License for many libraries. However, the Lesser license provides advantages in certain special circumstances. For example, on rare occasions, there may be a special need to encourage the widest possible use of a certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must be allowed to use the library. A more frequent case is that a free library does the same job as widely used non-free libraries. In this case, there is little to gain by limiting the free library to free software only, so we use the Lesser General Public License. In other cases, permission to use a particular library in non-free programs enables a greater number of people to use a large body of free software. For example, permission to use the GNU C Library in non-free programs enables many more people to use the whole GNU operating system, as well as its variant, the GNU/Linux operating system. Although the Lesser General Public License is Less protective of the users' freedom, it does ensure that the user of a program that is linked with the Library has the freedom and the wherewithal to run that program using a modified version of the Library. The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work based on the library" and a "work that uses the library". The former contains code derived from the library, whereas the latter must be combined with the library in order to run. GNU LESSER GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License Agreement applies to any software library or other program which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Lesser General Public License (also called "this License"). Each licensee is addressed as "you". A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables. The "Library", below, refers to any such software library or work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term "modification".) "Source code" for a work means the preferred form of the work for making modifications to it. For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library. Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does. 1. You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and distribute a copy of this License along with the Library. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) The modified work must itself be a software library. b) You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change. c) You must cause the whole of the work to be licensed at no charge to all third parties under the terms of this License. d) If a facility in the modified Library refers to a function or a table of data to be supplied by an application program that uses the facility, other than as an argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful. (For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply it, the square root function must still compute square roots.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Library, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Library, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Library. In addition, mere aggregation of another work not based on the Library with the Library (or with a work based on the Library) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices. Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy. This option is useful when you wish to copy part of the code of the Library into a program that is not a library. 4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange. If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code. 5. A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License. However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables. When a "work that uses the Library" uses material from a header file that is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law. If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of the Library will still fall under Section 6.) Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself. 6. As an exception to the Sections above, you may also combine or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications. You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things: a) Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.) b) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (1) uses at run time a copy of the library already present on the user's computer system, rather than copying library functions into the executable, and (2) will operate properly with a modified version of the library, if the user installs one, as long as the modified version is interface-compatible with the version that the work was made with. c) Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution. d) If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place. e) Verify that the user has already received a copy of these materials or that you have already sent this user a copy. For an executable, the required form of the "work that uses the Library" must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the materials to be distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute. 7. You may place library facilities that are a work based on the Library side-by-side in a single library together with other library facilities not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above. b) Give prominent notice with the combined library of the fact that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 9. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it. 10. Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties with this License. 11. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Library. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply, and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 12. If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Library under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 13. The Free Software Foundation may publish revised and/or new versions of the Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Library specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Library does not specify a license version number, you may choose any version ever published by the Free Software Foundation. 14. If you wish to incorporate parts of the Library into other free programs whose distribution conditions are incompatible with these, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Libraries If you develop a new library, and you want it to be of the greatest possible use to the public, we recommend making it free software that everyone can redistribute and change. You can do so by permitting redistribution under these terms (or, alternatively, under the terms of the ordinary General Public License). To apply these terms, attach the following notices to the library. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This library is free software; you can redistribute it and/or modify it under the terms of the GNU Lesser General Public License as published by the Free Software Foundation; either version 2.1 of the License, or (at your option) any later version. This library is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU Lesser General Public License for more details. You should have received a copy of the GNU Lesser General Public License along with this library; if not, write to the Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA Also add information on how to contact you by electronic and paper mail. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the library, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the library `Frob' (a library for tweaking knobs) written by James Random Hacker. , 1 April 1990 Ty Coon, President of Vice That's all there is to it! ======================================================================== * gcc gcc/ada/doc/share/copyright.tex ======================================================================== \emph{%(tool)s, The %(name)s Development Environment} \emph{%(edition)s} \begin{DUlineblock}{0em} \item[] Version %(version)s \item[] Date: %(date)s \end{DUlineblock} AdaCore Permission is granted to copy, distribute and/or modify this document under the terms of the GNU Free Documentation License, Version 1.3 or any later version published by the Free Software Foundation; with no Invariant Sections, with the Front-Cover Texts being ``GNAT Reference Manual'', and with no Back-Cover Texts.

[This is the first released version of the library GPL. It is numbered 2 because it goes with version 2 of the ordinary GPL.] Preamble ======== The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This license, the Library General Public License, applies to some specially designated Free Software Foundation software, and to any other libraries whose authors decide to use it. You can use it for your libraries, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the library, or if you modify it. For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You must make sure that they, too, receive or can get the source code. If you link a program with the library, you must provide complete object files to the recipients so that they can relink them with the library, after making changes to the library and recompiling it. And you must show them these terms so they know their rights. Our method of protecting your rights has two steps: (1) copyright the library, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the library. Also, for each distributor's protection, we want to make certain that everyone understands that there is no warranty for this free library. If the library is modified by someone else and passed on, we want its recipients to know that what they have is not the original version, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that companies distributing free software will individually obtain patent licenses, thus in effect transforming the program into proprietary software. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. Most GNU software, including some libraries, is covered by the ordinary GNU General Public License, which was designed for utility programs. This license, the GNU Library General Public License, applies to certain designated libraries. This license is quite different from the ordinary one; be sure to read it in full, and don't assume that anything in it is the same as in the ordinary license. The reason we have a separate public license for some libraries is that they blur the distinction we usually make between modifying or adding to a program and simply using it. Linking a program with a library, without changing the library, is in some sense simply using the library, and is analogous to running a utility program or application program. However, in a textual and legal sense, the linked executable is a combined work, a derivative of the original library, and the ordinary General Public License treats it as such. Because of this blurred distinction, using the ordinary General Public License for libraries did not effectively promote software sharing, because most developers did not use the libraries. We concluded that weaker conditions might promote sharing better. However, unrestricted linking of non-free programs would deprive the users of those programs of all benefit from the free status of the libraries themselves. This Library General Public License is intended to permit developers of non-free programs to use free libraries, while preserving your freedom as a user of such programs to change the free libraries that are incorporated in them. (We have not seen how to achieve this as regards changes in header files, but we have achieved it as regards changes in the actual functions of the Library.) The hope is that this will lead to faster development of free libraries. The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work based on the library" and a "work that uses the library". The former contains code derived from the library, while the latter only works together with the library. Note that it is possible for a library to be covered by the ordinary General Public License rather than by this special one. TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License Agreement applies to any software library which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Library General Public License (also called "this License"). Each licensee is addressed as "you". A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables. The "Library", below, refers to any such software library or work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term "modification".) "Source code" for a work means the preferred form of the work for making modifications to it. For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library. Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does. 1. You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and distribute a copy of this License along with the Library. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a. The modified work must itself be a software library. b. You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change. c. You must cause the whole of the work to be licensed at no charge to all third parties under the terms of this License. d. If a facility in the modified Library refers to a function or a table of data to be supplied by an application program that uses the facility, other than as an argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful. (For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply it, the square root function must still compute square roots.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Library, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Library, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Library. In addition, mere aggregation of another work not based on the Library with the Library (or with a work based on the Library) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices. Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy. This option is useful when you wish to copy part of the code of the Library into a program that is not a library. 4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange. If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code. 5. A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License. However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables. When a "work that uses the Library" uses material from a header file that is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law. If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of the Library will still fall under Section 6.) Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself. 6. As an exception to the Sections above, you may also compile or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications. You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things: a. Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.) b. Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution. c. If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place. d. Verify that the user has already received a copy of these materials or that you have already sent this user a copy. For an executable, the required form of the "work that uses the Library" must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute. 7. You may place library facilities that are a work based on the Library side-by-side in a single library together with other library facilities not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things: a. Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above. b. Give prominent notice with the combined library of the fact that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 9. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it. 10. Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 11. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Library. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply, and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 12. If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Library under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 13. The Free Software Foundation may publish revised and/or new versions of the Library General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Library specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Library does not specify a license version number, you may choose any version ever published by the Free Software Foundation. 14. If you wish to incorporate parts of the Library into other free programs whose distribution conditions are incompatible with these, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Libraries ============================================== If you develop a new library, and you want it to be of the greatest possible use to the public, we recommend making it free software that everyone can redistribute and change. You can do so by permitting redistribution under these terms (or, alternatively, under the terms of the ordinary General Public License). To apply these terms, attach the following notices to the library. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. ONE LINE TO GIVE THE LIBRARY'S NAME AND AN IDEA OF WHAT IT DOES. Copyright (C) YEAR NAME OF AUTHOR This library is free software; you can redistribute it and/or modify it under the terms of the GNU Library General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This library is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU Library General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307, USA. Also add information on how to contact you by electronic and paper mail. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the library, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the library `Frob' (a library for tweaking knobs) written by James Random Hacker.

Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. This version of the GNU Lesser General Public License incorporates the terms and conditions of version 3 of the GNU General Public License, supplemented by the additional permissions listed below. 0. Additional Definitions. As used herein, "this License" refers to version 3 of the GNU Lesser General Public License, and the "GNU GPL" refers to version 3 of the GNU General Public License. "The Library" refers to a covered work governed by this License, other than an Application or a Combined Work as defined below. An "Application" is any work that makes use of an interface provided by the Library, but which is not otherwise based on the Library. Defining a subclass of a class defined by the Library is deemed a mode of using an interface provided by the Library. A "Combined Work" is a work produced by combining or linking an Application with the Library. The particular version of the Library with which the Combined Work was made is also called the "Linked Version". The "Minimal Corresponding Source" for a Combined Work means the Corresponding Source for the Combined Work, excluding any source code for portions of the Combined Work that, considered in isolation, are based on the Application, and not on the Linked Version. The "Corresponding Application Code" for a Combined Work means the object code and/or source code for the Application, including any data and utility programs needed for reproducing the Combined Work from the Application, but excluding the System Libraries of the Combined Work. 1. Exception to Section 3 of the GNU GPL. You may convey a covered work under sections 3 and 4 of this License without being bound by section 3 of the GNU GPL. 2. Conveying Modified Versions. If you modify a copy of the Library, and, in your modifications, a facility refers to a function or data to be supplied by an Application that uses the facility (other than as an argument passed when the facility is invoked), then you may convey a copy of the modified version: a) under this License, provided that you make a good faith effort to ensure that, in the event an Application does not supply the function or data, the facility still operates, and performs whatever part of its purpose remains meaningful, or b) under the GNU GPL, with none of the additional permissions of this License applicable to that copy. 3. Object Code Incorporating Material from Library Header Files. The object code form of an Application may incorporate material from a header file that is part of the Library. You may convey such object code under terms of your choice, provided that, if the incorporated material is not limited to numerical parameters, data structure layouts and accessors, or small macros, inline functions and templates (ten or fewer lines in length), you do both of the following: a) Give prominent notice with each copy of the object code that the Library is used in it and that the Library and its use are covered by this License. b) Accompany the object code with a copy of the GNU GPL and this license document. 4. Combined Works. You may convey a Combined Work under terms of your choice that, taken together, effectively do not restrict modification of the portions of the Library contained in the Combined Work and reverse engineering for debugging such modifications, if you also do each of the following: a) Give prominent notice with each copy of the Combined Work that the Library is used in it and that the Library and its use are covered by this License. b) Accompany the Combined Work with a copy of the GNU GPL and this license document. c) For a Combined Work that displays copyright notices during execution, include the copyright notice for the Library among these notices, as well as a reference directing the user to the copies of the GNU GPL and this license document. d) Do one of the following: 0) Convey the Minimal Corresponding Source under the terms of this License, and the Corresponding Application Code in a form suitable for, and under terms that permit, the user to recombine or relink the Application with a modified version of the Linked Version to produce a modified Combined Work, in the manner specified by section 6 of the GNU GPL for conveying Corresponding Source. 1) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (a) uses at run time a copy of the Library already present on the user's computer system, and (b) will operate properly with a modified version of the Library that is interface-compatible with the Linked Version. e) Provide Installation Information, but only if you would otherwise be required to provide such information under section 6 of the GNU GPL, and only to the extent that such information is necessary to install and execute a modified version of the Combined Work produced by recombining or relinking the Application with a modified version of the Linked Version. (If you use option 4d0, the Installation Information must accompany the Minimal Corresponding Source and Corresponding Application Code. If you use option 4d1, you must provide the Installation Information in the manner specified by section 6 of the GNU GPL for conveying Corresponding Source.) 5. Combined Libraries. You may place library facilities that are a work based on the Library side by side in a single library together with other library facilities that are not Applications and are not covered by this License, and convey such a combined library under terms of your choice, if you do both of the following: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities, conveyed under the terms of this License. b) Give prominent notice with the combined library that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 6. Revised Versions of the GNU Lesser General Public License. The Free Software Foundation may publish revised and/or new versions of the GNU Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Library as you received it specifies that a certain numbered version of the GNU Lesser General Public License "or any later version" applies to it, you have the option of following the terms and conditions either of that published version or of any later version published by the Free Software Foundation. If the Library as you received it does not specify a version number of the GNU Lesser General Public License, you may choose any version of the GNU Lesser General Public License ever published by the Free Software Foundation. If the Library as you received it specifies that a proxy can decide whether future versions of the GNU Lesser General Public License shall apply, that proxy's public statement of acceptance of any version is permanent authorization for you to choose that version for the Library. ======================================================================== * newlib-cygwin-50e2a63b04bdd018484605fbb954fd1bd5147fa0/winsup/cygwin/include/sys/copying.dj ======================================================================== This is the file "copying.dj".
