25 /* This file is an addendum to m32c.cpu. Heavy use of C code isn't
26 appropriate in .cpu files, so it resides here. This especially applies
27 to assembly/disassembly where parsing/printing can be quite involved.
28 Such things aren't really part of the specification of the cpu, per se,
29 so .cpu files provide the general framework and .opc files handle the
30 nitty-gritty details as necessary.
