Hi Guys,

  I am applying the attached patch below to add support for Intel's
  iWMMXt processor to the ARM simulator.  (The old armulator based
  one, not the cgen based one).

  There are also some patches for GDB itself but I am holding off on
  submitting these until I can them for multi-arch issues.

Cheers
        Nick
