Bug ID: 106438
Summary: powerpc: ICE when building libgfortran with -lto: in
insert_value_copy_on_edge, at tree-outof-ssa.cc:334
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libfortran
Assignee: unassigned at gcc dot gnu.org
Reporter: msc at linux dot ibm.com
Target Milestone: ---
Compiling libgfortran with -lto (see small patch [1] below) is failing on
powerpc64le (testd on P10, but may apply to older processors as well) with
current trunk:

Small typo: I meant -flto, not -lto. The patch is OK though.

That just exposes the issue from the source.
Can you supply the full command line which is failing?

Created attachment 53350

Failing command
The failing command is the final link command to create libgfortran.so, so it's
rather long. I'm attaching it to the bug as a txt file, along with some
warnings that gcc emitted.

Quite probably a target issue, since -flto investigation is difficult without
native access lets see if target folks can get a handle on this (hint: reduce
the testcase to a few input files)
