* Remove remaining _HAVE_STRING_ARCH_* definitions (BZ #18858)Adhemerval Zanella2017-09-061-1/+0
| | | | | | | | | | | | | | | | | | | | | | | Since the removal of bits/string.h, _HAVE_STRING_ARCH_* are no longer used. This patch removes the unused macros from i686 and x86_64 sysdeps folder. Checked on x86_64-linux-gnu and i686-linux-gnu. * sysdeps/i386/i686/multiarch/strncpy.c (_HAVE_STRING_ARCH_strncpy): Remove define. * sysdeps/x86_64/multiarch/stpcpy.c (_HAVE_STRING_ARCH_stpcpy): Likewise. * sysdeps/x86_64/multiarch/strcspn.c (_HAVE_STRING_ARCH_strcspn): Likewise. * sysdeps/x86_64/multiarch/strncat.c (_HAVE_STRING_ARCH_strncat): Likewise. * sysdeps/x86_64/multiarch/strncpy.c (_HAVE_STRING_ARCH_strncpy): Likewise. * sysdeps/x86_64/multiarch/strpbrk.c (_HAVE_STRING_ARCH_strpbrk): Likewise. * sysdeps/x86_64/multiarch/strspn.c (_HAVE_STRING_ARCH_strspn): Likewise.
* Fix fallout from bits/string.h removal.Zack Weinberg2017-06-201-0/+2
| | | | | | | | | | | | | | | Remove one more string inline that was defined directly in string.h; in the absence of the rest of the inlines, it broke the build. Like other ifunc shims for these functions, x86_64/multiarch/{mem,st}pcpy.c need to define __NO_STRING_INLINES and NO_MEMPCPY_STPCPY_REDIRECT. * string/string.h (__mempcpy_inline): Delete. * sysdeps/x86_64/multiarch/mempcpy.c * sysdeps/x86_64/multiarch/stpcpy.c: Define NO_MEMPCPY_STPCPY_REDIRECT and __NO_STRING_INLINES before including string.h.
* x86-64: Implement strcpy family IFUNC selectors in CH.J. Lu2017-06-121-0/+41
Implement strcpy family IFUNC selectors in C. All internal calls within libc.so can use IFUNC on x86-64 since unlike x86, x86-64 supports PC-relative addressing to access the GOT entry so that it can call via PLT without using an extra register. For libc.a, we can't use IFUNC for functions which are called before IFUNC has been initialized. Use IFUNC internally reduces the icache footprint since libc.so and other codes in the process use the same implementations. This patch uses IFUNC for strcpy family functions within libc. * sysdeps/x86_64/multiarch/Makefile (sysdep_routines): Add strcpy-sse2 and stpcpy-sse2. * sysdeps/x86_64/multiarch/ifunc-unaligned-ssse3.h: New file. * sysdeps/x86_64/multiarch/stpcpy-sse2.S: Likewise. * sysdeps/x86_64/multiarch/stpcpy.c: Likewise. * sysdeps/x86_64/multiarch/stpncpy.c: Likewise. * sysdeps/x86_64/multiarch/strcpy-sse2.S: Likewise. * sysdeps/x86_64/multiarch/strcpy.c: Likewise. * sysdeps/x86_64/multiarch/strncpy.c: Likewise. * sysdeps/x86_64/multiarch/stpcpy.S: Removed. * sysdeps/x86_64/multiarch/stpncpy.S: Likewise. * sysdeps/x86_64/multiarch/strcpy.S: Likewise. * sysdeps/x86_64/multiarch/strncpy.S: Likewise. * sysdeps/x86_64/multiarch/stpncpy-c.c (weak_alias): New.
