When I messed with the "partial" module,
I compared CIL's normal output to the partially
evaluated output, like e.g.
cilly.byte --noPrintLn \
--out parteval.cil.c parteval.c
cilly.byte --noPrintLn \
--domakeCFG \
--dopartial --partial_root_function foo --partial_global_const \
--out parteval-do.cil.c parteval.c
diff -up parteval.cil.c parteval-do.cil.c
Not elegant, but simple.

AFAIK, there isn't.
Module "partial" has kind of preprocessor
character; it enables later analyses or
optimizations to kick in more effectively.
