Hi Chris,

  Right, I have checked in the (uploaded) patch to further improve the
consistency of the disassembler's output.

  With regard to LFM and SFM I do still think that they should disassembled and
displayed as they currently are, even if the architecture has been set to one
that *might* not support them.  In the spirit of compromise however I have added
the LDC and STC versions of the instructions as comments in the disassembler's

  So for example disassembling the binary values that have been mentioned in
this issue, I now get:

   0:   4c585ee5        ldclmi  14, cr5, [r8], {229}    ; 0xe5
   4:   01a23597        undefined instruction 0x01a23597
   8:   3d9da24e        lfmcc   f2, 1, [sp, #312]       ; (ldccc 2, cr10, [sp,
#312])   ; 0x138
   c:   46647659        strbmi  r7, [r4], -r9, asr r6
  10:   77c1cdb4        strbvc  ip, [r1, r4, lsr sp]
  14:   e640361f        strb    r3, [r0], -pc, lsl r6
  18:   4c585ee5        ldclmi  14, cr5, [r8], {229}    ; 0xe5
  1c:   d446399e        strble  r3, [r6], #-2462        ; 0x99e
  20:   11d87ed1        ldrsbne r7, [r8, #225]  ; 0xe1
  24:   44afa697        strtmi  sl, [pc], #1687 ; 2c <foo+0x2c>
  28:   d4bf78b4        ldrtle  r7, [pc], #2228 ; 30 <foo+0x30>
  2c:   bc041350        stclt   3, cr1, [r4], {80}      ; 0x50
