Bug ID: 120307
Summary: ICE in combine_with_ipa_count_within, at
profile-count.cc:410 during aarch64 -O3
profiledbootstrap
Product: gcc
Version: 16.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: acoplan at gcc dot gnu.org

unreduced testcase (src + profile data)
The attached unreduced testcase is extracted from an aarch64 -O3
profiledbootstrap, (configured --with-build-config=bootstrap-O3). It fails as
follows:
$ ls
optabs.gcda optabs.ii
$ ../xgcc -B .. -c -S -o /dev/null -O3 -fprofile-use -fno-exceptions optabs.ii
during IPA pass: inline
