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. 2022-01-12 Uroš Bizjak <ubizjak@gmail.com> gcc/ChangeLog: PR target/100637 PR target/103861 * config/i386/i386-expand.c (ix86_emit_vec_binop): New static function.
