Bug ID: 103425
Summary: 48% tramp3d regression between g:df1a0d526e2e4c75 and
g:9e026da720091704 with -Ofast -march=native at Zen
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: hubicka at gcc dot gnu.org
Target Milestone: ---
visible at https://lnt.opensuse.org/db_default/v4/CPP/graph?plot.0=171.576.0
and with LTO https://lnt.opensuse.org/db_default/v4/CPP/graph?plot.0=178.576.0
It lasts for 2 runs already so probably not a noise. Curiously I do not see it
on other testers (perhaps they need to run yet)

I hope it was not caused by my patch. As it could in theory cause cost
differences ....

Cannot reproduce that locally with -march=znver2 on a znver1 machine.

In meanwhile other testers picked the revision and it seems that indeed only
benzen machine reports this (it is AMD EPYC 7702). So it looks
microarchitecture specific issue.
