Make strcmp with unaligned load/store the defaulthjl/unaligned
Since strcmp_sse2_unaligned performs better on current Intel and AMD
processors, this patch makes it the default.
* sysdeps/x86_64/strcmp.S: Moved to ...
* sysdeps/x86_64/multiarch/strcmp-sse2.S: Here. Remove
"#if !IS_IN (libc)". Remove libc_hidden_builtin_def (STRCMP).
(STRCMP): Defined to __strcmp_sse2 if not defined.
* sysdeps/x86_64/multiarch/strcmp-sse2-unaligned.S: Moved to ...
* sysdeps/x86_64/strcmp.S: Here. Remove "#if IS_IN (libc)".
Add .text. Add libc_hidden_builtin_def (strcmp).
(__strcmp_sse2_unaligned): Renamed to ...
(strcmp): This.
* sysdeps/x86_64/multiarch/Makefile (sysdep_routines): Add
strcmp-sse2.
* sysdeps/x86_64/multiarch/strcasecmp_l-ssse3.S: Include
strcmp-sse2.S instead of ../strcmp.S.
* sysdeps/x86_64/multiarch/strcmp-ssse3.S: Likewise.
* sysdeps/x86_64/multiarch/strncase_l-ssse3.S: Likewise.
* sysdeps/x86_64/multiarch/strncmp-ssse3.S: Likewise.
* sysdeps/x86_64/multiarch/strcmp.S
[USE_AS_STRCMP] (STRCMP_SSE2): Set to __strcmp_sse2_unaligned.
[USE_AS_STRCMP] (STRCMP): Load __strcmp_sse2 instead of
STRCMP_SSE2.
[USE_AS_STRCMP] (strcmp): Defined __strcmp_sse2_unaligned if
in libc.
[!USE_AS_STRCMP]: Include strcmp-sse2S instead of ../strcmp.S.
* sysdeps/x86_64/strcasecmp_l.S: Include multiarch/strcmp-sse2.S
instead of strcmp.S. Add libc_hidden_builtin_def (STRCMP).
* sysdeps/x86_64/strncase_l.S: Likewise.
