There has been a fair amount of work on modifying executable files for
various purposes such as instrumentation and optimization. A Google
search on phrases like "binary rewriting", "binary translation", and
"link-time code optimization" should give you enough pointers to get
you started.

Well, we had an undergraduate student build, in one summer, a binary
rewriting system for Intel x86 executables under Linux (ELF format)
that would modify the code for instrumentation as well as optimization
purposes. It isn't *that* hard.:)
