If you're going to use a restricted C compiler to generate
assembler source code to import into an assembly prog,
you might consider using an assembler that can actually
understand complex expressions and generate the
equivalent optimised assembler in situ for you. Kind of
like very powerful macros. It can handle arrays in both
code and data space,  pointers and address arithmetic,
and early out operators such as && and ||. It produces
really tight code, with some expressions being reduced
down to single machine instructions. It also works with
16 as well as 8 bit values. Checkout
