Using the following structure definition and declarations:

struct foo$\{$

int $*$ptr$\_$x;

int b;

$\}$;

struct foo s$0$;

Show the MIPS instruction sequence needed to implement this C statement:

s$0.$b $=*($s$0.$ptr$\_$x$)+4$;

You may assume that all s# variables refer to the corresponding MIPS registers and that the variables and parts of the struct are placed on word boundries.

Note, you can assume that the s$0.$ptr$\_$x has been set to the legal address of an int.

You may use other t# registers if your solutions needs them.

Don't forget the restrictions on the use of pseudo$-$instructions!
