Bug ID: 95320
Summary: [11 Regression] ICE in odr_type_p, at ipa-utils.h:246,
during IPA pass: pure-const
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code
Severity: normal
Priority: P3
Component: ipa
Assignee: unassigned at gcc dot gnu.org
Reporter: burnus at gcc dot gnu.org
CC: ams at gcc dot gnu.org, marxin at gcc dot gnu.org
Target Milestone: ---
For some reason, this only occurs when compiling for AMDGCN and it seems to be
a recent regression.
The issue seems to affect nearly all testcases in libgomp, I get 2500+ FAIL.
For instance
gcc -fopenmp libgomp/testsuite/libgomp.c-c++-common/for-11.c
fails as:
during IPA pass: fnsummary
src/gcc-mainline/libgomp/testsuite/libgomp.c-c++-common/for-11.c:5: internal
