Jeffrey A. Law <law at redhat dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |law at redhat dot com --- Comment #6 from Jeffrey A. Law <law at redhat dot com> --- Right. This is a good example of where extracting the predicate analysis bits from tree-ssa-uninit.c would be useful elsewhere. The isolate-erroneous-paths bits don't help either because the dereference isn't in the same block as the PHI with the NULL argument (educated guess here) I'm a little surprised DOM jump threading didn't bb11->bb41 to bb31 though.
