ARM LEGv8 assembly code

For the following C statement, write the corresponding LEGv8 assembly code.

a. Assume that the variables i is assigned to register X3 respectively. Assume that the base address of the arrays A, B and C are assigned to registers X0 .. X2 respectively. Assume that the elements of both arrays are 8-byte words.

C[i] = A[i] + B[i]

b. Assume that the variables f, g, and h, have already been placed in registers X0 .. X2 respectively. Assume that the elements of both arrays are 8-byte words. Use a minimal number of LEGv8 assembly instructions.

f = (g 3) (h + 5);
