Steven Munroe <sjmunroe@us.ibm.com> * sysdeps/powerpc/dl-procinfo.c (_dl_powerpc_cap_flags): Add 4 new cap names to the beginning. Rename "cell" to "cellbe". (_dl_powerpc_platforms): New. * sysdeps/powerpc/dl-procinfo.h (_DL_HWCAP_FIRST): Decrease. (HWCAP_IMPORTANT): Remove power{4,5,5+} and cell. (_DL_PLATFORMS_COUNT, _DL_FIRST_PLATFORM): Define. (_DL_HWCAP_PLATFORM): Define to new mask. (_dl_platform_string, _dl_string_platform): New functions. * sysdeps/powerpc/sysdep.h (PPC_FEATURE_BOOKE, PPC_FEATURE_SMT, PPC_FEATURE_ICACHE_SNOOP, PPC_FEATURE_ARCH_2_05): Define.
