Let say we generate handlers with all possible cpu fixups. Very few
instructions would be removed so the disassembly should be quite
similar after patching. And by emitting some nice comments in the
generated code, it should be fairly obvious to get an idea of the
final code.
All fixups would be listed in a table with some flags to identify them
and a list of instructions which need to be relocated.
It seems to me that the kernel code would be much simpler than what we
have now. Regarding the script used to generate the assembly code, if
think it would be too.
Thanks,
Franck
