Check for some of the combinations not // anymore supported. // Some user header file might have defined this before. // All functions, except those with callbacks or those that // synchronize memory, are leaf functions. // GCC can always grok prototypes. For C++ programs we add throw() // to help it optimize the function calls. But this works only with // gcc 2.8.x and egcs. For gcc 3.2 and up we even mark C functions // as non-throwing using a function attribute since programs can use // the -fexceptions options for C code as well. // Compilers that are not clang may object to // #if defined __clang__ && __has_extension(...) // even though they do not need to evaluate the right-hand side of the &&. // These two macros are not used in glibc anymore. They are kept here // only because some other projects expect the macros to be defined. // For these things, GCC behaves the ANSI way normally, // and the non-ANSI way under -traditional. // This is not a typedef so `const __ptr_t' does the right thing. // C++ needs to know that types and declarations are C, not C++. // Fortify support. // Support for flexible arrays. // Headers that should use flexible arrays only if they're "real" // (e.g. only if they won't affect sizeof()) should test // #if __glibc_c99_flexarr_available. // __asm__ ("xyz") is used throughout the headers to rename functions // at the assembly language level. This is wrapped by the __REDIRECT // macro, in order to support compilers that can do this some other // way. When compilers don't support asm-names at all, we have to do // preprocessor tricks instead (which don't have exactly the right // semantics, but it's the best we can do). // // Example: // int __REDIRECT(setpgrp, (__pid_t pid, __pid_t pgrp), setpgid); // // #elif __SOME_OTHER_COMPILER__ // // # define __REDIRECT(name, proto, alias) name proto; _Pragma("let " #name " = " #alias) // GCC has various useful declarations that can be made with the // `__attribute__' syntax. All of the ways we use this do fine if // they are omitted for compilers that don't understand it. // At some point during the gcc 2.96 development the `malloc' attribute // for functions was introduced. We don't want to use it unconditionally // (although this would be possible) since it generates warnings. // Tell the compiler which arguments to an allocation function // indicate the size of the allocation. // At some point during the gcc 2.96 development the `pure' attribute // for functions was introduced. We don't want to use it unconditionally // (although this would be possible) since it generates warnings. // This declaration tells the compiler that the value is constant. // At some point during the gcc 3.1 development the `used' attribute // for functions was introduced. We don't want to use it unconditionally // (although this would be possible) since it generates warnings. // Since version 3.2, gcc allows marking deprecated functions. // Since version 4.5, gcc also allows one to specify the message printed // when a deprecated function is used. clang claims to be gcc 4.2, but // may also support this feature. // At some point during the gcc 2.8 development the `format_arg' attribute // for functions was introduced. We don't want to use it unconditionally // (although this would be possible) since it generates warnings. // If several `format_arg' attributes are given for the same function, in // gcc-3.0 and older, all but the last one are ignored. In newer gccs, // all designated arguments are considered. // At some point during the gcc 2.97 development the `strfmon' format // attribute for functions was introduced. We don't want to use it // unconditionally (although this would be possible) since it // generates warnings. // The nonull function attribute allows to mark pointer parameters which // must not be NULL. // If fortification mode, we warn about unused results of certain // function calls which can lead to problems. // Forces a function to be always inlined. // The Linux kernel defines __always_inline in stddef.h (283d7573), and // it conflicts with this definition. Therefore undefine it first to // allow either header to be included first. // Associate error messages with the source location of the call site rather // than with the source location inside the function. // GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99 // inline semantics, unless -fgnu89-inline is used. Using __GNUC_STDC_INLINE__ // or __GNUC_GNU_INLINE is not a good enough check for gcc because gcc versions // older than 4.3 may define these macros and still not guarantee GNU inlining // semantics. // // clang++ identifies itself as gcc-4.2, but has support for GNU inlining // semantics, that can be checked for by using the __GNUC_STDC_INLINE_ and // __GNUC_GNU_INLINE__ macro definitions. // GCC 4.3 and above allow passing all anonymous arguments of an // __extern_always_inline function to some other vararg function. // It is possible to compile containing GCC extensions even if GCC is // run in pedantic mode if the uses are carefully marked using the // `__extension__' keyword.
