Bug ID: 109796
Summary: 548.exchange2_r compiled with -O2 -flto regressed by
5% on aarch64 between r14-135-gd06e9264b0192c and
r14-192-g636e2273aec555
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: jamborm at gcc dot gnu.org
Blocks: 26163
Target Milestone: ---
Host: aarch64-linux
Target: aarch64-linux
The slowdown can be seen clearly at
https://lnt.opensuse.org/db_default/v4/SPEC/graph?plot.0=581.407.0
Fortran at -O2 may not be super important and the slowdown is not huge but it
looks very stable so maybe worth a look. I do not see any similar regression
on a different architecture or configuration.
