[PATCH] i386: Remove mode size check in ix86_get_ssemov

2020-04-11 Thread H.J. Lu via Gcc-patches
Even though ix86_hard_regno_mode_ok doesn't allow xmm16-xmm31 nor ymm16-ymm31 in 128/256 bit modes when AVX512VL is disabled, reload can still generate reg to reg moves with xmm16-xmm31 and ymm16-ymm31 in 128/256 bit modes. Remove mode size check in ix86_get_ssemov. gcc/ PR target/94561
