I noticed that sysdeps/x86/cpu-features.h had conditionals on whether to define HAS_CPUID, HAS_I586 and HAS_I686 with a long list of preprocessor macros for i686-and-later processors which however was out of date. This patch avoids the problem of the list getting out of date by instead having conditionals on all the (few, old) pre-i686 processors for which GCC has preprocessor macros, rather than the (many, expanding list) i686-and-later processors. It seems HAS_I586 and HAS_I686 are unused so the only effect of these macros being missing is that 32-bit glibc built for one of these processors would end up doing runtime detection of CPUID availability. i386 builds are prevented by a configure test so there is no need to allow for them here. __geode__ (no long nops?) and __k6__ (no CMOV, at least according to GCC) are conservatively handled as i586, not i686, here (as noted above, this is a theoretical distinction at present in that only HAS_CPUID appears to be used). Tested for x86. * sysdeps/x86/cpu-features.h [__geode__ || __k6__]: Handle like [__i586__ || __pentium__]. [__i486__]: Handle explicitly. (HAS_CPUID): Define to 1 if above macros are undefined. (HAS_I586): Likewise. (HAS_I686): Likewise. |
