4. Convert the below C code snippet to LEGv8 assembly code. Base address of x is stored in register X19. Assume variables a, b, and c are stored in registers X20, X21, and X22 respectively. Assume all values are 64-bits. Do not use divide and multiply instructions in your code. Comment your assembly code. (25 Points) x[1] = a + b; x[2] x[2*a] + C; x[c/4] = X[C] + (b 2)
