--- Comment #6 from Jeffrey A. Law <law at redhat dot com> --- Actually the 79095-4 test is testing that we do loop distribution and propagation of constants into the the memset call and that after propagation we realize there's a bogus path that we actually can't remove given the state of the IL. Martin's changes to <vector> compromise that test in that it provides enough information to the compiler and the compiler should eliminate the problematic call to memset. If we collapse things down to C it's actually not going to be a terribly interesting test. And I'd prefer to avoid the CPP output as it's likely to have host/target dependencies that are going to cause long term headaches. I think we should just declare this test compromised. Martin's test from r255753 has reasonable tests and thus I don't think it's even worth turning this into a verification that Martin's work has the intended effects.
