Noah Goldstein 64b8b6516b x86: Add evex optimized functions for the wchar_t strcpy family ... Implemented: wcscat-evex (+ 905 bytes) wcscpy-evex (+ 674 bytes) wcpcpy-evex (+ 709 bytes) wcsncpy-evex (+1358 bytes) wcpncpy-evex (+1467 bytes) wcsncat-evex (+1213 bytes) Performance Changes: Times are from N = 10 runs of the benchmark suite and are reported as geometric mean of all ratios of New Implementation / Best Old Implementation. Best Old Implementation was determined with the highest ISA implementation. wcscat-evex -> 0.991 wcscpy-evex -> 0.587 wcpcpy-evex -> 0.695 wcsncpy-evex -> 0.719 wcpncpy-evex -> 0.694 wcsncat-evex -> 0.979 Code Size Changes: This change increase the size of libc.so by ~6.3kb bytes. For reference the patch optimizing the normal strcpy family functions decreases libc.so by ~5.7kb. Full check passes on x86-64 and build succeeds for all ISA levels w/ and w/o multiarch.		2022-11-08 19:22:33 -08:00
