Since apply_irel is called before memcpy and mempcpy are called, we can use IFUNC memcpy and mempcpy in libc.a. * sysdeps/x86_64/memmove.S (MEMCPY_SYMBOL): Don't check SHARED. (MEMPCPY_SYMBOL): Likewise. * sysdeps/x86_64/multiarch/ifunc-impl-list.c (__libc_ifunc_impl_list): Test memcpy and mempcpy in libc.a. * sysdeps/x86_64/multiarch/memcpy-ssse3-back.S: Also include in libc.a. * sysdeps/x86_64/multiarch/memcpy-ssse3.S: Likewise. * sysdeps/x86_64/multiarch/memmove-avx512-no-vzeroupper.S: Likewise. * sysdeps/x86_64/multiarch/memcpy.c: Also include in libc.a. (__hidden_ver1): Don't use in libc.a. * sysdeps/x86_64/multiarch/memmove-sse2-unaligned-erms.S (__mempcpy): Don't create a weak alias in libc.a. * sysdeps/x86_64/multiarch/memmove-vec-unaligned-erms.S: Support libc.a. * sysdeps/x86_64/multiarch/mempcpy.c: Also include in libc.a. (__hidden_ver1): Don't use in libc.a.
