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 -> 0.938 wcscat-evex -> 0.991 wcscpy-evex -> 0.587 wcpcpy-evex -> 0.695 wcsncpy-evex -> 0.719 wcpncpy-evex -> 0.694 wcsncat-evex -> 0.959 Code Size Changes: This change (compared with the last two commits without it) increase the size of libc.so by 19392 bytes. For reference this entire patchset increases libc.so by 2624 bytes (so without the wide-character functions libc.so would decrease by 16768 bytes). Full check passes on x86-64 and build succeeds for all ISA levels w/ and w/o multiarch. --- Results attached to the evex/avx2 patches. sysdeps/x86_64/Makefile | 5 + sysdeps/x86_64/multiarch/Makefile | 26 +++- sysdeps/x86_64/multiarch/ifunc-impl-list.c | 135 +++++++++++++++++++- sysdeps/x86_64/multiarch/ifunc-wcs.h | 60 +++++++++ sysdeps/x86_64/multiarch/wcpcpy-avx2-rtm.S | 3 + sysdeps/x86_64/multiarch/wcpcpy-avx2.S | 8 ++ sysdeps/x86_64/multiarch/wcpcpy-evex.S | 8 ++ sysdeps/x86_64/multiarch/wcpcpy-generic.c | 27 ++++ sysdeps/x86_64/multiarch/wcpcpy.c | 37 ++++++ sysdeps/x86_64/multiarch/wcpncpy-avx2-rtm.S | 3 + sysdeps/x86_64/multiarch/wcpncpy-avx2.S | 8 ++ sysdeps/x86_64/multiarch/wcpncpy-evex.S | 8 ++ sysdeps/x86_64/multiarch/wcpncpy-generic.c | 27 ++++ sysdeps/x86_64/multiarch/wcpncpy.c | 37 ++++++ sysdeps/x86_64/multiarch/wcscat-avx2-rtm.S | 3 + sysdeps/x86_64/multiarch/wcscat-avx2.S | 10 ++ sysdeps/x86_64/multiarch/wcscat-evex.S | 9 ++ sysdeps/x86_64/multiarch/wcscat-generic.c | 27 ++++ sysdeps/x86_64/multiarch/wcscat.c | 37 ++++++ sysdeps/x86_64/multiarch/wcscpy-avx2-rtm.S | 3 + sysdeps/x86_64/multiarch/wcscpy-avx2.S | 7 + sysdeps/x86_64/multiarch/wcscpy-evex.S | 7 + sysdeps/x86_64/multiarch/wcscpy-generic.c | 3 +- sysdeps/x86_64/multiarch/wcscpy.c | 21 +++ sysdeps/x86_64/multiarch/wcsncat-avx2-rtm.S | 3 + sysdeps/x86_64/multiarch/wcsncat-avx2.S | 9 ++ sysdeps/x86_64/multiarch/wcsncat-evex.S | 9 ++ sysdeps/x86_64/multiarch/wcsncat-generic.c | 27 ++++ sysdeps/x86_64/multiarch/wcsncat.c | 34 +++++ sysdeps/x86_64/multiarch/wcsncpy-avx2-rtm.S | 3 + sysdeps/x86_64/multiarch/wcsncpy-avx2.S | 7 + sysdeps/x86_64/multiarch/wcsncpy-evex.S | 7 + sysdeps/x86_64/multiarch/wcsncpy-generic.c | 27 ++++ sysdeps/x86_64/multiarch/wcsncpy.c | 37 ++++++ sysdeps/x86_64/wcpcpy-generic.c | 31 +++++ sysdeps/x86_64/wcpcpy.S | 41 ++++++ sysdeps/x86_64/wcpncpy-generic.c | 31 +++++ sysdeps/x86_64/wcpncpy.S | 41 ++++++ sysdeps/x86_64/wcscat-generic.c | 31 +++++ sysdeps/x86_64/wcscat.S | 41 ++++++ sysdeps/x86_64/wcscpy.S | 2 + sysdeps/x86_64/wcsncat-generic.c | 31 +++++ sysdeps/x86_64/wcsncat.S | 39 ++++++ sysdeps/x86_64/wcsncpy-generic.c | 31 +++++ sysdeps/x86_64/wcsncpy.S | 41 ++++++ 45 files changed, 1036 insertions(+), 6 deletions(-) create mode 100644 sysdeps/x86_64/multiarch/ifunc-wcs.h create mode 100644 sysdeps/x86_64/multiarch/wcpcpy-avx2-rtm.S create mode 100644 sysdeps/x86_64/multiarch/wcpcpy-avx2.S create mode 100644 sysdeps/x86_64/multiarch/wcpcpy-evex.S create mode 100644 sysdeps/x86_64/multiarch/wcpcpy-generic.c create mode 100644 sysdeps/x86_64/multiarch/wcpcpy.c create mode 100644 sysdeps/x86_64/multiarch/wcpncpy-avx2-rtm.S create mode 100644 sysdeps/x86_64/multiarch/wcpncpy-avx2.S create mode 100644 sysdeps/x86_64/multiarch/wcpncpy-evex.S create mode 100644 sysdeps/x86_64/multiarch/wcpncpy-generic.c create mode 100644 sysdeps/x86_64/multiarch/wcpncpy.c create mode 100644 sysdeps/x86_64/multiarch/wcscat-avx2-rtm.S create mode 100644 sysdeps/x86_64/multiarch/wcscat-avx2.S create mode 100644 sysdeps/x86_64/multiarch/wcscat-evex.S create mode 100644 sysdeps/x86_64/multiarch/wcscat-generic.c create mode 100644 sysdeps/x86_64/multiarch/wcscat.c create mode 100644 sysdeps/x86_64/multiarch/wcscpy-avx2-rtm.S create mode 100644 sysdeps/x86_64/multiarch/wcscpy-avx2.S create mode 100644 sysdeps/x86_64/multiarch/wcscpy-evex.S create mode 100644 sysdeps/x86_64/multiarch/wcsncat-avx2-rtm.S create mode 100644 sysdeps/x86_64/multiarch/wcsncat-avx2.S create mode 100644 sysdeps/x86_64/multiarch/wcsncat-evex.S create mode 100644 sysdeps/x86_64/multiarch/wcsncat-generic.c create mode 100644 sysdeps/x86_64/multiarch/wcsncat.c create mode 100644 sysdeps/x86_64/multiarch/wcsncpy-avx2-rtm.S create mode 100644 sysdeps/x86_64/multiarch/wcsncpy-avx2.S create mode 100644 sysdeps/x86_64/multiarch/wcsncpy-evex.S create mode 100644 sysdeps/x86_64/multiarch/wcsncpy-generic.c create mode 100644 sysdeps/x86_64/multiarch/wcsncpy.c create mode 100644 sysdeps/x86_64/wcpcpy-generic.c create mode 100644 sysdeps/x86_64/wcpcpy.S create mode 100644 sysdeps/x86_64/wcpncpy-generic.c create mode 100644 sysdeps/x86_64/wcpncpy.S create mode 100644 sysdeps/x86_64/wcscat-generic.c create mode 100644 sysdeps/x86_64/wcscat.S create mode 100644 sysdeps/x86_64/wcsncat-generic.c create mode 100644 sysdeps/x86_64/wcsncat.S create mode 100644 sysdeps/x86_64/wcsncpy-generic.c create mode 100644 sysdeps/x86_64/wcsncpy.S
