Update.
2000-11-15 Andreas Jaeger <aj@suse.de> * elf/cache.c (struct cache_entry): Use uint64_t for hwcap. (print_entry): Likewise. (add_to_cache): Likewise. * elf/ldconfig.h (add_to_cache): Change prototype for hwcap change. * elf/ldconfig.c (struct lib_entry): Use uint64_t for hwcap. (path_hwcap): Likewise. (search_dir): Likewise. * sysdeps/generic/dl-cache.c (HWCAP_CHECK): Handle platform. * elf/cache.c (add_to_cache): Handle 64 bit hwcap entry. * sysdeps/unix/sysv/linux/sparc/sparc32/dl-procinfo.h (_dl_platform_string): New. (_DL_HWCAP_PLATFORM): New. (_dl_string_platform): New. * sysdeps/unix/sysv/linux/sparc/sparc64/dl-procinfo.h: Likewise. * sysdeps/generic/dl-procinfo.h (_DL_HWCAP_COUNT): New. (_dl_string_platform): New. (_DL_HWCAP_PLATFORM): New. (_dl_platform_string): New. * sysdeps/unix/sysv/linux/i386/dl-procinfo.h: Added x86 platform recognition. (_DL_HWCAP_COUNT): New. (_dl_string_platform): New. (_DL_HWCAP_PLATFORM): New. (_dl_platform_string): New.
