a. What is the purpose of the stack?

b. Write the sequence of instructions needed to push registers X1 and X2 onto the stack.

c. Using your LEGv8 reference card and textbook as helps, translate the following assembly instruction into its 32-bit machine code, using hexadecimal representation:

LDUR X2, [X17, #8]

d. Implement the following pseudo-code loop into assembly language:

for ( i = 0; i < 10;="" i="i" +1="">

array[i] = i

Assume (1) no restrictions on register use, (2) the array elements are stored a 64-bit integers (8-bytes), and (3) that the label array is defined with the 32-bit memory address, pointing to the first element in the array.
