Hi,
I've noticed that a test in g++.dg/tree-ssa/pr45605.C is Xfailed, even
though early FRE now does the devirtualization that it tests for.
True, the current scan happens over the SSA dump (which implies the
front-end was somehow supposed to do it?) but I think that given we do
perform the optimization, checking that we continue to do so is
useful, hence the following change.
Tested by adding to a successful bootstrap and test run on x86_64.
Unless anyone objects, I will commit the patch tomorrow.
Thanks,
Martin
