3. (10 p.) Suppose that the target assembly language for a compiler has these 5 instructions (same as in the book on page 62).

push address

add

sub

mul

pop address

Each arithmetic instruction pops an integer into the right operand, then pops an integer into the left operand and pushes the result of the operation on the stack. Translate the following assignments. Standard precedence and associativity rules apply. Process the variables in the same order as they appear in the assignments.

(a) total := a + b c + d

(b) result a b + (c d)
