Below is a MIPS assembly function called foo with some test code preceding it. .data_a: .word 2, 1, 3, 4, 0 .text .globl mainmain: … la $a0,_a # $a0 = &a; li $a1,3 # $a1 = 3; jal foo # call foo; … jr $ra # return;foo: li $v0,-1 move $t2,$zeroL1: lw $t1,0($a0) beq $t1,$zero,L3 beq $t1,$a1,L2 addiu $a0,$a0,4 addiu $t2,$t2,1 j L1L2: move $v0,$t2L3: jr $ra (a) Cut and past the assembly code of the function foo() in your answer and place meaningful comments by each of the assembly instructions. This is required and will help you understand the function. (b) What is the value returned from foo() in $v0 when called from the test code? (c) In general, what does foo() do? (d) Is there any potential issue when this program is loaded to the memory and executes? If it does, describe the problem.
