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
during GIMPLE pass: vect
opts.c: In function 'common_handle_option':
opts.c:1456:1: internal compiler error: in vect_peel_nonlinear_iv_init, at
