decompiling compiled emacs lisp

[Dhruva Krishnamurthy]

Hello,
        I have a XEmacs compiled emacs lisp file. There are some
        incompatibilities between functions in Emacs and XEmacs which I need
        to fix. I do not have the original emacs lisp source. Is there a way
        to decompile an elc file? This request might rather strange If it
        does, please ignore this posting.

Does the output of M-x disassemble help ?

This works but I will have to do it for each function. I wonder how I can take
care of other entities if they are byte compiled (variable declarations etc..)
Anyway, fortunately I found the raw e-lisp file and am spared of doing this
manually.

Thanks anyway,

You can look at `load-history' too see which functions and variables were
defined when you loaded the elc file.
