Suppose we want to generate assembly code for the following C function:

long shift(unsigned x, unsigned y){

return (x>>4 & y<<2);

}

The code below is a portion of the assembly code that performs the actual shifts and leaves the final value in register %rax. Two instructions have been omitted. Parameters x and y are stored in registers %rdi and %rsi respectively.

shift_right_left:

movl %edi, %eax

---------------------

movl %esi, %ecx

---------------------

---------------------

ret

Fill in the missing instructions where the dashed lines are.
