Commit Message

Uros Bizjak Jan. 12, 2022, 7:06 p.m. UTC
Add CC clobber to 32-bit vector mode logic insns to allow variants with
general-purpose registers.  Also improve ix86_sse_movcc to emit insn with
CC clobber for narrow vector modes in order to re-enable conditional moves
for 16-bit and 32-bit narrow vector modes with -msse2.
