Re: PR/18308: ice-on-valid because of non-GIMPLE


It looks like phiopt is essentially a fold() on COND_EXPRs that if-conversion produces, and that could expose more optimization opportunities.

IIRC someone actually reimplemented phiopt using fold :-) It's on the list of things to examine once we start looking at 4.1 stuff.

It is on my to-do list to see at what Andrew Pinski changed for phiopt in tcb, and adapt my patch to those changes.
