Zack Weinberg cab4d74b01 Add utility macros for clang detection, and deprecation with messages. ... There are three new macros added to features.h and sys/cdefs.h: * __glibc_clang_prereq: just like __GNUC_PREREQ, but for clang. * __glibc_clang_has_extension: wraps clang's intrinsic __has_extension. Writing "#if defined __clang__ && __has_extension (...)" doesn't work, because compilers other than clang will object to the unknown macro __has_extension even though they don't need to evaluate it. Instead, write "#if __glibc_clang_has_extension (...)". * __attribute_deprecated_msg__(msg): like __attribute_deprecated__, but if possible, prints a message. The first two are used to define the third. The third will be used in subsequent patches. * include/features.h (__glibc_clang_prereq): New macro. * misc/sys/cdefs.h (__glibc_clang_has_extension) (__attribute_deprecated_msg__): New macros.		2016-08-03 14:03:46 -04:00
