--- Comment #8 from Jan Hubicka <hubicka at gcc dot gnu.org> --- Reading the log, it gamess regression at 14th should not be gather/scatter because it reproduces on zen2 where we disable them. About the 19th regression, it would be nice to also bisect it (hopefully it will reproduce with -flto as discussed earlier). The reason is that it reproduces at ia64 even with profile feedback https://gcc.opensuse.org/gcc-old/SPEC/CFP/sb-terbium-head-64-FDO/recent.html which seems to disprove the likely suspect that it is a result of predictor changes from that day (mostly disproves: predictors still do affect FDO path but it is unlikely they affect it importantly unless there is other bug)
