You are given the following information. A function with prototype

void decode$1($long $*$xp$,$ long $*$yp$,$ long $*$zp$)$;

is compiled into assembly code, yielding the following:

# void decode$1($long $*$xp$,$ long $*$yp$,$ long $*$zp$)$

# xp in $\%$rdi, yp in $\%$rsi, zp in $\%$rdx

decode$1$:

movq $(\%$rdi$),\%$r$8$

movq $(\%$rsi$),\%$rcx

movq $(\%$rdx$),\%$rax

movq $\%$r$8,(\%$rsi$)$

movq $\%$rcx$,(\%$rdx$)$

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

ret

Parameters xp$,$ yp$,$ and zp are stored in registers $\%$rdi, $\%$rsi, and $\%$rdx$,$ respectively.
