Ok.

Ok.

I wouldn't suggest writing an X86NASMPrinter: just change the current 
Intel printer to do what you want.  Noone is currently using the intel 
printer, so you can do what you wish to it.

I don't know which you would prefer.  I'm actively (but slowly) hacking on 
the ELF writer in my spare time.  It will probably be a lot easier to 
write the COFF writer after the ELF write is done, so you can use it as an 
example.

In any case, getting the nasm writer working will be much easier still.
