Bart Oldeman	b073d759d0	x86_64: clobber all xmm registers after vzeroupper As observed using GCC 10 using -march=native -ftree-vectorize on Knights Landing, it is now smart enough to find clobbers inside non-inlined static functions. In particular, sgemv counted on a kernel to preserve the whole %ymm2 register (since it was not in the clobber list), but the top part was destroyed by vzeroupper. This caused many tests to fail. This patch makes sure all xmm (and ymm/zmm by extension) registers are listed as clobbered to avoid this happening, as most kernels already did correctly in fact.	5 years ago
