Q4: Compile the C-Language statement A[100] = A[0] * 2; into MIPS assembly code using the minimum number of instructions. Assume that register $s2 holds the base of A (an array of integers).

Q5: Assuming A is an integer array with base in $s4 and that the compiler associates the integer variables g, i, and n with the registers $s1, $s2, and $s3, respectively. What is the compiled MIPS assembly code for the following C code segment?

for (i = 0; i < n; i++)

g = g + A[i];

Q6: Assume that argument registers $a0 and $a1 initially contain positive integers a and b, respectively. Assume that $v0 is used for the result.

add $t0, $0, $0

loop beq $a1, $0, exit

add $t0, $t0, $a0

addi $a1, $a1, 1

j loop

exit add $v0, $t0, $0
