This problem is about operand modes, in particular about memory addressing using

the operand modes described in lecture and the textbook. The following shows the contents of a

portion of the program memory $($locations $0$x$10000$ through $0$x$10040$higher addresses are at the

top$),$ and certain registers. All contents are $64-$bit quantities.

For each of the following instructions, say what value ends up in the destination register. Each

instruction starts with the state shown above, i$.$e$.,$ the effects do not accumulate.

a$.$ movq $(\%$rdi$),\%$rax

b$.$ movq $(\%$rdi,$\%$rsi$),\%$rax

c$.$ movq $8(\%$rdi,$\%$rcx$,4)\%$r$8$

d$.$ movq $-8(\%$rdi,$\%$rsi$),\%$rbx
