Consider the following code, in which we have omitted the expression being computed:

short scale$3($short x$,$ short y$,$ short z$)\{$

short t $=\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_$ ;

return t;

$\}$

Compiling the actual function with gcc yields the following assembly code:

short scale$3($short x$,$ short y$,$ short z$)$

x in $\%$rdi, y in $\%$rsi, z in $\%$rdx

scale$3$:

leaq $(\%$rdi,$\%$rsi,$5),\%$rax

leaq $9(\%$rdx$,\%$rsi,$3),\%$rdx

leaq $(\%$rax,$\%$rdx$,7),\%$rdx
