Hi!


I could use some help on this. I have to mention that i am not sure if
what i am asking is possible!!
I will like to add new instructions in the instruction set of an
existing machine's gcc toolchain. Furthermore i will like to do that
"dynamic", thus no rebuild of the whole gcc toolchain is required
anytime i am adding a new instruction.
So, i am using inline assembly to pass the new instruction to the
assembly file and this works fine. Then i am using the -t (--itbl)
option of the assembler and provide the instruction format in the
INSTTBL file. Bad this one does not work. It gives me an internal error
complaining for a bad opcode.
Is this approach correct?
Any suggestions?? Or any manual i should read for this job?


Thanks,
N.
