That doesn't sound like the right place to me. We want the same code to
be generated whether users write and || directly or write corresponding
sequences of if

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
