Best Old Implementation was determined with the highest ISA implementation. wcscat-avx2 -> 0.975 wcscpy-avx2 -> 0.591 wcpcpy-avx2 -> 0.698 wcsncpy-avx2 -> 0.730 wcpncpy-avx2 -> 0.711 wcsncat-avx2 -> 0.954 Code Size Changes: This change increase the size of libc.so by ~11kb bytes. For reference the patch optimizing the normal strcpy family functions decreases libc.so by ~5.2kb. Full check passes on x86-64 and build succeeds for all ISA levels w/ and w/o multiarch. --- sysdeps/x86_64/multiarch/Makefile | 12 ++++ sysdeps/x86_64/multiarch/ifunc-impl-list.c | 66
