On second thought, no need to hack gpsim.
Would just take a simple Python script to:
- generate a gpsim script containing 'processor', 'load' and
'disassemble' commands
- run gpsim against this script, and snarf the output
- parse the output and weed out superflous lines
- parse the .map file and find out where everything lives
- cross reference everything, and generate a final .dasm
file, which could be assembled to produce exactly the
same binary as the original
If/when I hack up such a thing (perhaps later today), I'll post it to
this list.
Cheers
David
