            Bug ID: 108004
           Summary: x-form logical operations with dot instructions are
                    not emitted.
           Product: gcc
           Version: 13.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: guihaoc at gcc dot gnu.org
  Target Milestone: ---

//test case
int foo (int a, int b, int c, int d)
{
  return (a & b) > 0 ? c : d;
}

//assemble on P9
        and 3,3,4
        cmpwi 0,3,0
        isel 5,5,6,1
        extsw 3,5

The "and" and "cmpwi" can be optimized to "and." instruction. The same as "=
or"
and "xor".=
