Status: UNCONFIRMED
Keywords: missed-optimization, needs-bisection
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org

there is a slowdown of 436.cactusADM SPEC2006 benchmark, 11% for Ofast native
LTO PGO and 17% for Ofast native LTO.
This is on aarch64. I haven't seen similar slowdowns on other architectures.

Did you mean -Ofast native PGO? both linked runs are PGO.
In any case, confirmed. Running bisect.

Yes I did. I meant PGO and wrote LTO. My bad :).
