--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> --- (In reply to Richard Biener from comment #2) > One reason is that this is one of the few users of rhs_to_tree, aka we go > back to GENERIC and its folding. Yes I noticed that when I disabled forward_propagate_into_gimple_cond and got a failure dealing with `&a->b != c`. I am thinking I need to write out to a file when forward_propagate_into_gimple_cond/forward_propagate_into_comparison gets back something that is folded to find more rather than just disabling it and finding testsuite failures. Because there could some that the testsuite is not testing for.
