--- Comment #21 from Andrew Pinski <pinskia at gcc dot gnu.org> --- Note -O1 completes the testcase in comment #0 in a reasonable amount of time now. I don't know if it was an issue though. -O2 still ICEs with checking and flatten. I was looking at some of the gimple level code and noticed a lot of copy prop for aggregates that is happening and wonder how much will speed up this case.
