/* 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.
