Q$5.$ Compile the following C code snippet.

struct test$\_$t $\{$

short int $x$;

short int $y$;

$\}$;

int foo$3($int $*$list$,$ struct test$\_$t $t)\{$

int ret;

ret $=t.x$;

unsigned int $i$;

for $($int $i=0$; $i<mn\; id="EditorElement\_197752">8</mn>$; $i++)\{$

ret $=$ ret $+$ list $[i]+$ t$.$y;

$\}$

return ret;

$\}$

a$)$ How many registers are used for the function arguments?

b$)$ If t$.$x $=02264$ and t$.$y $=0267a,$ how is the argument $t$ stored in the

parameter register$($s$)?($Hint: Compile with $O1$ and examine how $t$ is accessed$)$

c$)$ In $O2,$ how many loop iterations do the assembly code perform?
