Re: question on a "logical" cmp utility

I needed to do this recently when I needed to prove to our QA team
that a bug fix had affected just the specified region. I came up with
a charmingly simple technique. I disassembled the before and after
executables, and compared those. This had several useful effects:


1) All the objects were concatenated by the linker, meaning I only
had to compare one (big) file.
2) Where there were differences I could easily tell whether they
were the correct ones.


I'm sure that a disassembler could be hooked up in series with text
processing programs that would remove any extraneous headers, if
needed. I suspect that such header removal would be easier in the text
domain than in the binary domain.
