The following three problems in this Exercise refer to a function f that calls another function func. The code for C function func is already compiled in another module using the MIPS calling convention from Figure 2.14. The function declaration for func is “int func(int a, int b);”. The code for function f is as follows:

Figure 2.14

Translate function f into MIPS assembly language, also using the MIPS calling convention from Figure 2.14. If you need to use registers $t0 through $t7, use the lower-numbered registers first.
