            Bug ID: 29526
           Summary: x86: inconsistent suffix recognition in Intel syntax
                    mode
           Product: binutils
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gas
          Assignee: unassigned at sourceware dot org
          Reporter: jbeulich at suse dot com
  Target Milestone: ---

Intel syntax, we've been accepting such forever. But this then needs to be
consistent - observe the anomaly for MOVD when assembling

        nopw    [rbx]
        nopd    [rbx]

        addw    [rbx], 5
