That doesn't sound like the right place to me. We want the same code to

Hi,
Several ports in gcc support conditional compare instructions which is
an efficient way to handle SHORT_CIRCUIT. But the information is not
represented in TREE or GIMPLE. And it depends on BRANCH_COST and
combine pass to generate the instructions.
To explicitly represent the semantics of cond
