#define strcspn strpbrk
x86-64: Implement strcspn/strpbrk/strspn IFUNC selectors in C Implement strcspn/strpbrk/strspn 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 strcspn/strpbrk/strspn functions within libc. * sysdeps/x86_64/multiarch/Makefile (sysdep_routines): Add strcspn-sse2, strpbrk-sse2 and strspn-sse2. * sysdeps/x86_64/strcspn.S (STRPBRK_P): Removed. Check USE_AS_STRPBRK instead of STRPBRK_P. * sysdeps/x86_64/strpbrk.S (USE_AS_STRPBRK): New. * sysdeps/x86_64/multiarch/ifunc-sse4_2.h: New file. * sysdeps/x86_64/multiarch/strcspn-sse2.S: Likewise. * sysdeps/x86_64/multiarch/strcspn.c: Likewise. * sysdeps/x86_64/multiarch/strpbrk-sse2.S: Likewise. * sysdeps/x86_64/multiarch/strpbrk.c: Likewise. * sysdeps/x86_64/multiarch/strspn-sse2.S: Likewise. * sysdeps/x86_64/multiarch/strspn.c: Likewise. * sysdeps/x86_64/multiarch/strcspn.S: Removed. * sysdeps/x86_64/multiarch/strpbrk.S: Likewise. * sysdeps/x86_64/multiarch/strspn.S: Likewise. * sysdeps/x86_64/multiarch/strpbrk-c.c: Remove "#ifdef SHARED" and "#endif".
