Bart Oldeman	60e49b851c	Fix typo in clobber list, should be xmm14 instead of ymm14.	2022-12-06 16:30:46 -05:00
Bart Oldeman	5ceca1a4d8	Add sscal.c + microkernels for Haswell, Zen, Skylake and newer. Unlike [dcz]scal, sscal still used the original GotoBLAS SSE code from scal_sse.S. This code follows dscal as closely as possible, except for the inc_x > 1 code for which a plain C loop is used much like the one in cscal.c, instead of an adaptation of the SSE2 asm code of dscal.c (I tried but the performance wasn't better than the plain C loop).	2022-12-06 14:05:49 -05:00
