--- Comment #5 from Richard Biener <rguenth at gcc dot gnu.org> ---
So the bug is probably latent before the PR90078 change with a "proper"
profile?
(the GIMPLE FE will get counter/freq inputs for GCC 10)
Btw, we have precedence of using GMP for niter analysis so we could switch
the cost computation to using GMP avoiding infinity for anything but the
specially marked IVs. Would that be prohibitly expensive?
Can you construct a non-GRAPHITE testcase (just reproduce the GRAPHITE
produced loop nest?)?
