--- Comment #5 from Drea Pinski <pinskia at gcc dot gnu.org> ---
Does this show up on aarch64?
Is this with -g also?
So the slow down back in Nov 2025 looks like it is the remove_forwarder_block
patch set.
The speed up in May 2026 looks it was the cselib/valtracking changes.
This is why I ask if this is with -g?
We might be hitting a valtracking issue again with slightly different cfg.
So it is not about LTO directly but rather a known valtracking issue.
