            Bug ID: 117618
           Summary: mmix: may need adaptation for C23 varargs
           Product: gcc
           Version: 15.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: sjames at gcc dot gnu.org
                CC: hp at gcc dot gnu.org
            Blocks: 114175
  Target Milestone: ---

Split out from PR114175 (see
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=114175#c64).

This target needs to check if it needs a tweak for handling C23 varargs like in
r14-9503-g218d17496122abe1fd831bd003f129310b32ca83.

If gcc.dg/c23-stdarg* passes on this target, it should be fine as-is.
