--- Comment #10 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Do we really need separate _bcst patterns btw? Wouldn't it be better to just have some predicate and corresponding constaint that would allow normal MEM vectors as well as these broadcast from single element and just use that predicate wherever the broadcasts are allowed? Probably would need multiple of them though, even when the main would turn to be just memory_operand if TARGET_AVX512F is false, some instructions only use EVEX encoding if some other TARGET_AVX* is on...
