Hi -
: [...] So -- any thoughts [re. multiple ISAs in opcodes/]?
For an internal port, several ISAs are plopped together in one set
of opcodes files, separated by ISA. Instruction names (not mnemonics),
ifields, etc., are all suffixed to avoid collisions. Sim-side code is
generated into mostly independent files (separate @prefix@).
It works fine. Look around the code base for a certain co-processor.
