--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> ---
There's nothing IPA in it so the testcase can be cut to contain only a single
function.  I have a patch to improve VRP time a bit.  The PTA slowness will
be quite difficult to deal with.  FRE is somewhat high up because we have
very many SSA names and tracking availability has some constant overhead.
