| /* 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. |
