1. LEGv8 coding

(a) Find at least five different ways to assign 0 to register X4.

(b) For the following C statement, write the corresponding LEGv8 assembly code. Assume that the C variables a, b, and c, have already been placed in registers X0, X1, and X2 respectively. Use a minimal number of LEGv8 assembly instructions.

a = (b + c) 15;

(c) For the following C statement, write a minimal sequence of LEGv8 assembly instructions that performs the identical operation. Assume X8 = A, and X12 is the base address of the array C.

A = C[2] << 2;
