            Bug ID: 109458
           Summary: invalid use 'z' operand modifier in some cases mention
                    the 'Z' operand modifier
           Product: gcc
           Version: 13.0
            Status: UNCONFIRMED
          Keywords: diagnostic
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: pinskia at gcc dot gnu.org
  Target Milestone: ---
            Target: x86_64-*-*

The problem here is the code in i386 does this:

case 'z':
...
          if (GET_MODE_CLASS (GET_MODE (x)) == MODE_FLOAT)
            warning (0, "non-integer operand used with operand code %<z%>");
          /* FALLTHRU */

        case 'Z':

...
          else
            {
              output_operand_lossage ("invalid operand type used with "
                                      "operand code 'Z'");
              return;
            }

          output_operand_lossage ("invalid operand size for operand code 'Z'");


So the error messages for 'Z' modifier is shared with 'z' but only references
'Z'.
