Chapter 2, Problem 2.34E

Explanation of Solution

Corresponding MIPS instruction:

The corresponding MIPS instruction for the given C code is as follows:

#$sp = $sp -4

f:addi $sp, $sp, -4

#store the value

sw $ra, 0($sp)

#call the function

jal func

#$a0 = $v0 + $0

add $a0, $v0, $0

#$a1 = $a2 + $a3

add $a1, $a2, $a3

#call the function

jal func

#load the value

lw $ra, 0($sp)

#$sp = $sp + 4

addi $sp, $sp, 4

#return to caller
