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
