            Bug ID: 21124
           Summary: [PowerPC] Source and target registers must be
                    different for some load instructions - should be
                    decoded as invalid
           Product: binutils
           Version: 2.26
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: binutils
          Assignee: unassigned at sourceware dot org
          Reporter: nholcomb at wisc dot edu
  Target Milestone: ---

The source and target registers must be different for some load instructions.

For example,
7c 00 02 28 is an invalid instruction, but decoding the instruction with
libopcodes returns "lqarx r0, 0, r0".
