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

   Each section is delimited with start and end markers.
