--- Comment #53 from Jeffrey A. Law <law at redhat dot com> --- And presumably walking forward/backward from the equivalency point to determine if an object is derived from or is used to derive a pointer is insufficient because the equivalency point and casting to/from pointer types might be in different functions? Is this the final straw and do we just stop recording these conditional equivalences when both sides are SSA_NAMEs and declare the fallout unavoidable? And note I believe we do similar stuff in the RTL optimizers too.
