--- Comment #5 from Martin Liška <marxin at gcc dot gnu.org> --- (In reply to Eric Botcazou from comment #4) > Let's just back out my couple of patches to ipa-devirt.c. Nobody seems to > care about PR ipa/83983 so I guess I no longer do either. Sorry for overlooking the PR83983, I can help you with that next week. Now I've got reduced 1/6 of preprocessed files. Hope that having a reasonable small test-case would allow you do debug that and fix?
