Hi!
The various blendm expanders look like:
(define_insn "<avx512>_blendm<mode>"
[(set (match_operand:V48_AVX512VL 0 "register_operand" "=v")
(vec_merge:V48_AVX512VL
(match_operand:V48_AVX512VL 2 "nonimmediate_operand" "vm")
(match_operand:V48_AVX512VL 1 "register_operand" "v")
One could argue this ordering is just asking for trouble.
Ultimately, I'll defer to Uros and Kirill.
