a, b, and c are indexed from 1 to n in
each dimension. You may use MIPS assembly language notation in place
of the book's three-address intermediate code notation, if you are
more comfortable with that. You should assume (in this case) that
scalar variables live in registers. You can assume the existence of
labels a, b, and c at the base of each array, and
use the notation
(a-4) to indicate the (constant) address four bytes before the start of
a, etc.
Even if you use the book's three-address intermediate code format, I
would prefer that you not use the bracket notation, but rather did the
address addition explicitly. If you use MIPS assembly language
notation in place of the three-address intermediate code, you can skip
parts b and h, which call for generating ``target-machine code.'' If,
on the other hand, you use three-address intermediate code, then go
ahead and do parts b and h but using the MIPS as your target machine,
rather than the one defined in the book.
Also, briefly describe any major opportunities for optimizing this routine that are not covered by the exercise.
