             Bug #: 14875
           Summary: Disassembling m68k shows scales which the m68000 does
                    not support
           Product: binutils
           Version: 2.23
            Status: NEW
          Severity: minor
          Priority: P2
         Component: binutils
        AssignedTo: address@hidden
        ReportedBy: address@hidden
    Classification: Unclassified


The M68000 chip does not support scales in the "Memory Indirect Preindexed"
mode. objdump should not display the scale if disassembling of the M68000 is
requested via -mm68k:68000

Also a minor thing is that the offsets are printed with too many leading zeros.
