           Summary: ARM disassembler disassembles rrx as rrx #0
           Product: new-bugs
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: new bugs
        AssignedTo: unassignedbugs at nondot.org

(trunk rev 110038)

Opcode e1887067 is disassembled as

  orr  r7, r8, r7, rrx #0

However the RRX shift does not take an argument. The correct form, I believe,
would be just

  orr  r7, r8, r7, rrx
