2014-09-16Revert to defining __extern_inline only for gcc-4.3+ (BZ #17266)Siddhesh Poyarekar1-3/+5
The check for only __GNUC_STDC_INLINE__ and __GNUC_GNU_INLINE__ may not be sufficient since those flags were added during initial support for C99 inlining semantics. There is also a problem with always defining __extern_inline and __extern_always_inline, since it enables inline wrapper functions even when GNU inlining semantics are not guaranteed. This, along with the possibility of such wrappers using redirection (btowc for example) could result in compiler generating an infinitely recusrive call to the function. In fact it was such a recursion that led to this code being written the way it was; see: https://bugzilla.redhat.com/show_bug.cgi?id=186410 The initial change was to fix bugs 14530 and 13741, but they can be resolved by checking if __fortify_function and/or __extern_always_inline are defined, as it has been done in this patch. In addition, I have audited uses of __extern_always_inline to make sure that none of the uses result in compilation errors. There is however a regression in this patch for llvm, since it reverts the llvm expectation that __GNUC_STDC_INLINE__ or __GNUC_GNU_INLINE__ definition imply proper extern inline semantics. 2014-09-16 Siddhesh Poyarekar <siddhesh@redhat.com> Jakub Jelinek <jakub@redhat.com> [BZ #17266] * libio/stdio.h: Check definition of __fortify_function instead of __extern_always_inline to include bits/stdio2.h. * math/bits/math-finite.h [__USE_XOPEN || __USE_ISOC99]: Also check if __extern_always_inline is defined. [__USE_MISC || __USE_XOPEN]: Likewise. [__USE_ISOC99] Likewise. * misc/sys/cdefs.h (__fortify_function): Define only if __extern_always_inline is defined. [!__cplusplus || __GNUC_PREREQ (4,3)]: Revert to defining __extern_always_inline and __extern_inline only for g++-4.3 and newer or a compatible gcc.
2014-02-21Complete _BSD_SOURCE / _SVID_source followup cleanup.Joseph Myers2-12/+12
This patch completes the headers cleanup consequent on removal of _BSD_SOURCE and _SVID_SOURCE (apart from any subsequent deprecations): * #endif conditionals that referred to BSD or SVID are updated. * Redundant __USE_* tests in cases involving __USE_MISC are removed. This includes cases such as __USE_MISC || __USE_ISOC99, where __USE_MISC is redundant (because __USE_MISC is only ever defined in the default / _DEFAULT_SOURCE / _GNU_SOURCE case, when __USE_ISOC99 is also defined; the same applies to the non-XSI-extended POSIX versions), and cases involving __USE_GNU, where __USE_GNU is redundant (because if __USE_GNU is defined, so are the other __USE_* macros). There may well be other cases of __USE_FOO || __USE_BAR tests that could be simplified because one macro implies the other; this patch only addresses cases involving __USE_MISC.
