            Bug ID: 20699
           Summary: [libopcodes][x86] Decodes invalid 32-bit address for a
                    64-bit MPX instruction
           Product: binutils
           Version: 2.26
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: binutils
          Assignee: unassigned at sourceware dot org
          Reporter: njholcomb at wi dot rr.com
  Target Milestone: ---

Libopcodes produces invalid 32-bit address for a 64-bit MPX instruction.

Output: addr32 bndstx %bnd0, -0x76a5963e(%eip) # 0xffffffff895a69cb
Bytes: 67 41 0f 1b 05 c2 69 5a 89

This instruction should be shown as invalid because 64-bit MPX instructions
cannot act on 32-bit addresses.
