	It's not possible.  Short of writing a disassembler, it can't be done.
You can get some partially informative information by using:

	cc -qlist file.c

This produces output into 'file.lst'.  Probably not exactly what you're looking
for, but it might be of some use.

	Correct.  As mentioned above, it's not supported by the AIX C compiler.

	True.  The compiler goes straight to machine code.  It doesn't 
translate to assembler first.
