Hi Reporter,

  Please could you give me more details of how you generated this bug ?

  I tried the following test:

  % cat pr22493.s
        .text
        push {sp}

  % arm-none-eabi-as -march=armv7-a pr22493.s -o pr22493.o
  % arm-none-eabi-objdump -d pr22493.o
  Disassembly of section .text:

  00000000 <.text>:
     0: e52dd004        push    {sp}            ; (str sp, [sp, #-4]!)

  So, the correct STMDB encoding is being used, although the disassembler does 
  have an incorrect comment describing the instruction.

Cheers
  Nick
