            Bug ID: 116045
           Summary: -march=znver4 does not enable SHSTK but -march=native
                    does
           Product: gcc
           Version: 15.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: rguenth at gcc dot gnu.org
  Target Milestone: ---

It looks like i386-isa.def lacks SHSTK and thus PTA_ZNVER4 cannot enable it.

But OTOH with -march=native I do get flags that have no corresponding PTA_*,
like in this case -mshstk
