* sysdeps/x86_64/memset.S: Reduce size of tables for PIC.
2008-03-07 Ulrich Drepper <drepper@redhat.com>
* sysdeps/x86_64/rtld-memset.c: New file.
2008-02-26 Harsha Jagasia <harsha.jagasia@amd.com>
* sysdeps/x86_64/cacheinfo.c (NOT_USED_RIGHT_NOW): Remove ifdef guards.
* sysdeps/x86_64/memset.S: Rewrite non-SSE code path as tuned for AMD
Barcelona machine. Make default fall through branch of
__x86_64_preferred_memory_instruction check as the integer code path.
2007-10-15 Ulrich Drepper <drepper@redhat.com>
* sysdeps/x86_64/cacheinfo.c (__x86_64_shared_cache_size): Define.
(init_cacheinfo): Initialize it.
* sysdeps/x86_64/memset.S: Use __x86_64_shared_cache_size.
Always define bzero.
Remove non-glibc code.
* sysdeps/x86_64/bzero.S: Make an empty file.
2007-10-15 H.J. Lu <hongjiu.lu@intel.com>
* sysdeps/x86_64/cacheinfo.c
(__x86_64_preferred_memory_instruction): New variable.
(init_cacheinfo): Initialize __x86_64_preferred_memory_instruction.
* sysdeps/x86_64/memset.S: Rewrite.
