operators and strings in MIPS

Question

I'm trying to figure out how to do this in MIPS:

Example:

sum(7,sum(subtraction(0,5),multiplication(division(7,2),3)))

Starting from left to right, where sum , subtraction , multiplication , division are strings that have the same functions of the basic operators. So, to do the first sum you need 2 numbers so the other sum is called. To do the second sum we need to do the subtraction and so on.

I was thinking to do it with labels but how can i assign an operator to a string?

Answer 1

You need to write the following functions that each take two arguments and return a result: sum, subtraction, multiplication, division . Then you need to call the functions in the correct order with the correct arguments.

You should study the MIPS calling convention to see how to write the functions.
