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
y port.
In the patch, dummy conditional_compare for i386 and arm are added for test.
Bootstrap on x86-64 and ARM Chromebook.
No ICE and runtime errors in regression tests.
Thanks!

Hi,
The patch makes several functions global, which will be used when
expanding ccmp instructions.
The other change in this patch is to check CCMP when turning code into
