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