Question $1$: RISC$-$V Caller$-$Callee Conventions $(30$ points$)$

a$)[15$ points$]$ Assume you are given the following code block. Write corresponding RISC$-$V

assembly code, considering the caller$-$callee conventions. You may take a look at the name of the

registers from the table given below.

int foo$()\{$

$...$

int a $=2$ ;

int b $=3$;

int c $=$ bar$($a$,$ b$)$;

return c;

$\}$

int bar$($int x$,$ int y$)\{$

return x $*$ y;

$\}$
