Problem 2. This question is about assembly instructions and operand modes. For each of the following descriptions, give a single x8664 assembly instruction and operands to implement the described semantics. Example: Copy the low-order 4 bytes of register \%rdi into the low-order 4 bytes of register \%rdx. movl % edi, % edx a. Load 8 bytes from memory beginning at the address stored in % rdi, into % rax. b. Store the low-order 2 bytes of %rcx into memory 16 bytes past the address stored in %rsi. c. Multiply the 8-byte value in \%rax by 8 . Do not use mul or imul. d. Multiply the 8-byte value in % rdx by 9 , subtract 14 , and put the result in % rsi
