--- Comment #20 from Jeffrey A. Law <law at redhat dot com> --- And FWIW, the test in this BZ is totally compromised on the trunk. Two primary reasons. First DOM does a much better job at finding & eliminating redundant loads. Second, erroneous path isolation finds a store to *0, it wipes out the RHS of that store allowing massive cleanups by DCE. I'll see if I can reasonably derive a testcase from 68654.
