--- Comment #3 from Tom de Vries <vries at gcc dot gnu.org> ---
The investigation in the gdb PR has identified a range of bad commits.
First bad commit:
- commit aae723d360c
("sra: SRA of non-escaped aggregates passed by reference to calls")
First good commit after first bad commit:
- commit cee7d080d5c
("Ignore conditions guarding __builtin_unreachable in inliner metrics")
It's not clear whether the problem has been fixed, or just no longer triggers.
