            Bug ID: 108601
           Summary: [13 Regression] vector peeling ICEs with PGO + LTO +
                    IPA inlining in gcc_r in SPEC2017
           Product: gcc
           Version: 13.0
            Status: UNCONFIRMED
          Keywords: ice-on-valid-code
          Severity: normal
          Priority: P3
         Component: tree-optimization
          Assignee: unassigned at gcc dot gnu.org
          Reporter: tnfchris at gcc dot gnu.org
  Target Milestone: ---

PGO seems fine, LTO seems fine, but PGO + LTO + increase inlining makes it
crash.

Full options:

-fprofile-generate -mcpu=native -Ofast -fomit-frame-pointer -flto=auto --param
ipa-cp-eval-threshold=1 --param ipa-cp-unit-growth=80

GCC 12 seems fine.

I'm still trying to reduce (it's a combination of my worst nightmares :( ), but
in the mean time here's the crash
