Question

CS51 Lab 8 1. Assume x goes to Ss0, y goes to $s1, and z goes to Ss2. Convert the following C code to MIPS. Use labels Else, Exit, and Loop when needed MIPS if (x== y) { y=y+z; else z=z-x; while (x < z) ( y=y-z; for (int x=1; x < 5; x++){ Y--i

Answer 1

Below is the MIPS code for the above C code snippets:

C	MIPS
if (x==y) { y=y+z; } else{ z=z-x }	beq $s0, $s1, ELSE add $s1, $s1, $s2 ELSE: sub $s2, $s2, $s1
While(x<z) { y=y-z; x++; }	bge $s0, $s3, DONE sub $s2 $s2, $s3 addi $s1, $s1, 1 DONE:
for (int x=1; x<5;x++){ z=x+y; y--;	# <init> ori $s0,1 # if (<cond>) L1: blez $s0, 5, DONE # <for-body> add $s3, $s0, $s1 addi $s2, $s2, -1 DONE:
