Consider the following y86 code:

.pos 0
irmovq list, %rcx
irmovq 8, %rsi
xorq %rdx, %rdx
loop: mrmovq (%rcx), %rax
andq %rax, %rax
je done
addq %rax, %rdx
addq %rsi, %rcx
jmp loop
done: halt
.align 8
list: .quad 0xa
.quad 0xb0
.quad 0xc00
.quad 0xd000
.quad 0

what is stored in register %rdx when the halt statement is reached? give your answer in hex without the leading 0x.
