/* This file is an addendum to frv.cpu.  Heavy use of C code isn't
27 
   appropriate in .cpu files, so it resides here.  This especially applies
28 
   to assembly/disassembly where parsing/printing can be quite involved.
29 
   Such things aren't really part of the specification of the cpu, per se,
30 
   so .cpu files provide the general framework and .opc files handle the
31 
   nitty-gritty details as necessary.
