| 25 | /* This file is an addendum to sh-media.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. | |
