When disassembling (or simulating the execution of) anything, you
usually have to specify a-priori the ISA of the binary dump.  (If you
want to try auto-detection, that'd have to be done via hand-written
code in the .opc file or elsewhere.)  For example, see how
disasemble_info* is passed into the generated default_print_insn()
function; or examples like sh* with its compact & media ISA's or m32rc
with its m16c/m32c.
