            Bug ID: 122166
           Summary: Look into setting PROP_last_full_fold for -Og earlier
           Product: gcc
           Version: 16.0
            Status: UNCONFIRMED
          Keywords: missed-optimization
          Severity: enhancement
          Priority: P3
         Component: tree-optimization
          Assignee: unassigned at gcc dot gnu.org
          Reporter: pinskia at gcc dot gnu.org
  Target Milestone: ---

I can't remember where this was mentioned on the list but Richi mentioned that
we should set PROP_last_full_fold earlier for -Og. I even was looking into it
before Richi mentioned it but never got around to figuring it fully out.

My thinking is setting it after inlining. The only issue is
__builtin_constant_p handling but maybe that is ok.
