ALL_SSE_REGS : TARGET_SSE ? SSE_REGS : NO_REGS" "@internal For AVX512VL, any EVEX encodable SSE register (@code{%xmm0-%xmm31}), otherwise any SSE register.") But these instructions aren't available with EVEX encoding. The x register constraint should be used. ^ permalink raw reply [flat|nested] 5+ messages in thread
