            Bug ID: 91305
           Summary: ICF compile-time issues
           Product: gcc
           Version: 10.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: ipa
          Assignee: unassigned at gcc dot gnu.org
          Reporter: rguenth at gcc dot gnu.org

  Target Milestone: ---

The testcase for PR91257 (https://gcc.gnu.org/bugzilla/attachment.cgi?id=46627)
shows 5% compile-time is spent in IPA ICF (it does unify 6 identical large
functions down to 1 so overall compile-time wise it's a clear win).
