This is wrapped by the __REDIRECT 446 // macro, in order to support compilers that can do this some other 447 // way. When compilers don't support asm-names at all, we have to do 448 // preprocessor tricks instead (which don't have exactly the right 449 // semantics, but it's the best we can do). 450 // 451 // Example: 452 // int __REDIRECT(setpgrp, (__pid_t pid, __pid_t pgrp), setpgid); 453 454 // 455 // #elif __SOME_OTHER_COMPILER__ 456 // 457 // # define __REDIRECT(name, proto, alias) name proto; _Pragma("let " #name " = " #alias) 458 459 // GCC has various useful declarations that can be made with the 460 // `__attribute__' syntax.

We don't want to use it unconditionally 465 // (although this would be possible) since it generates warnings. 466 467 // Tell the compiler which arguments to an allocation function 468 // indicate the size of the allocation. 469 470 // At some point during the gcc 2.96 development the `pure' attribute 471 // for functions was introduced. We don't want to use it unconditionally 472 // (although this would be possible) since it generates warnings. 473 474 // This declaration tells the compiler that the value is constant. 475 476 // At some point during the gcc 3.1 development the `used' attribute 477 // for functions was introduced. We don't want to use it unconditionally 478 // (although this would be possible) since it generates warnings. 479 480 // Since version 3.2, gcc allows marking deprecated functions. 481 482 // Since version 4.5, gcc also allows one to specify the message printed 483 // when a deprecated function is used. clang claims to be gcc 4.2, but 484 // may also support this feature. 485 486 // At some point during the gcc 2.8 development the `format_arg' attribute 487 // for functions was introduced. We don't want to use it unconditionally 488 // (although this would be possible) since it generates warnings. 489 // If several `format_arg' attributes are given for the same function, in 490 // gcc-3.0 and older, all but the last one are ignored. In newer gccs, 491 // all designated arguments are considered. 492 493 // At some point during the gcc 2.97 development the `strfmon' format 494 // attribute for functions was introduced. We don't want to use it 495 // unconditionally (although this would be possible) since it 496 // generates warnings. 497 498 // The nonull function attribute allows to mark pointer parameters which 499 // must not be NULL. 500 501 // If fortification mode, we warn about unused results of certain 502 // function calls which can lead to problems. 503 504 // Forces a function to be always inlined. 505 // The Linux kernel defines __always_inline in stddef.h (283d7573), and 506 // it conflicts with this definition. Therefore undefine it first to 507 // allow either header to be included first. 508 509 // Associate error messages with the source location of the call site rather 510 // than with the source location inside the function. 511 512 // GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99 513 // inline semantics, unless -fgnu89-inline is used. Using __GNUC_STDC_INLINE__ 514 // or __GNUC_GNU_INLINE is not a good enough check for gcc because gcc versions 515 // older than 4.3 may define these macros and still not guarantee GNU inlining 516 // semantics. 517 // 518 // clang++ identifies itself as gcc-4.2, but has support for GNU inlining 519 // semantics, that can be checked for by using the __GNUC_STDC_INLINE_ and 520 // __GNUC_GNU_INLINE__ macro definitions. 521 522 // GCC 4.3 and above allow passing all anonymous arguments of an 523 // __extern_always_inline function to some other vararg function. 524 525 // It is possible to compile containing GCC extensions even if GCC is 526 // run in pedantic mode if the uses are carefully marked using the 527 // `__extension__' keyword. But this is not generally available before 528 // version 2.8. 529 530 // __restrict is known in EGCS 1.2 and above. 531 532 // ISO C99 also allows to declare arrays as non-overlapping.
