Bug ID: 122456
Summary: [16 regression] LTO+profiledbootstrap failure on
aarch64 since r16-4604-g8b9cd6490ce507
Product: gcc
Version: 16.0
Status: UNCONFIRMED
Keywords: build, wrong-code
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: [email protected]
Blocks: 114725
Target Milestone: ---
Target: aarch64-*-*
r16-4604-g8b9cd6490ce507 has broken LTO+profiledbootstrap on aarch64,
apparently miscompiling lto1 during stagetrain. It crashes during
stagefeedback while linking cc1.
