            Bug ID: 105643
           Summary: [13 Regression] Code-Size regression for specrate
                    538.imagick_r
           Product: gcc
           Version: 13.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: tree-optimization
          Assignee: unassigned at gcc dot gnu.org

  Target Milestone: ---

We found on Intel platform, commit r13-128-g938a02a589dc22
(938a02a589dc22cef65bba2b131fc9e4874baddb) results 53.7% codesize increment
when compiled with march_native_ofast_lto(-march=3Dnative -Ofast -funroll-l=
oops
-flto) for specrate 538.imagick_r on SkylakeW, Cascade Lake and IceLake.

On Zen3 Server/Client code size looks alright.=
