Depending on your objectives, you might consider the following. It can yield
portability and tracability to the original assembler, but it ain't pretty:


Declare in C a bunch of ints named R1, R2, R3 ... <number of regs on hardwre>
Declare an array of ints to correspond to memory
Define a macro for each machine instruction (the "Load Address(1,2,3)"
    macro might expand to R1 := R2+3, for example. Pardon my syntax.
Make global changes to munge the assembly syntax into C, if required
Keep the assembly source, with comments, and optimize, optimize, optimize.


Like I said, not pretty, but ...
