Consider five global integer variables a, b, and c are defined in a C program as follow. int a, b, c, d, e; The size of int is 4 bytes and the base address is placed in the global pointer register ($gp). As a result, a, b, c, d, and e are available at $gp, $gp+4, and so on. Translate the following statements from C to MIPS. (a) a = b + c; (b) a = (b - c) + (d - e); Tips: (1) each statement may need multiple MIPS instructions. (2) use load and store instructions to move the variables between memory and registers.
