There is no support at present. But I believe it would be fairly simple to
port - it's just no-one has ever paid us to. The only significant part of a
simulator port obviously is the I/O interface - the ARM simulator (an old
version of the ARMulator if I remember right) uses Angel SWIs to do all
this stuff.
