tcg: try sti when moving a constant into a dead memory temp
This comes from free from unifying tcg_reg_alloc_mov and tcg_reg_alloc_movi's handling of TEMP_VAL_CONST. It triggers often on moves to cc_dst, such as the following translation of "sub $0x3c,%esp": before: after: subl $0x3c,%ebp subl $0x3c,%ebp movl %ebp,0x10(%r14) movl %ebp,0x10(%r14) movl $0x3c,%ebx movl $0x3c,0x2c(%r14) movl %ebx,0x2c(%r14) Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Message-Id: <1473945360-13663-1-git-send-email-pbonzini@redhat.com> Reviewed-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
