Bug ID: 110988
Summary: ICE when building 523.xalancbmk_r with pgo and lto
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: gcov-profile
Assignee: unassigned at gcc dot gnu.org
Reporter: fkastl at suse dot cz
CC: hubicka at gcc dot gnu.org, marxin at gcc dot gnu.org
Target Milestone: ---
Host: x86_64-linux
Target: x86_64-linux
On x86_64 Zen3-based CPU (and probably others) building 523.xalancbmk_r fails
with an ICE in the final build step.
We have bisected this to 2e93b92c1ec5fbbbe10765c6e059c3c90d564245 (Fix profile
update after cancelled loop distribution).
The backtrace is
during GIMPLE pass: vect
./xalanc/PlatformSupport/XalanArrayAllocator.hpp: In member function
'createEntry':
./xalanc/PlatformSupport/XalanArrayAllocator.hpp:174:9: internal compiler
