2. (10 p.) Suppose that the target assembly language for a compiler has these 5 instructions (same as in the book on page 61). load address, reg add reg, reg, reg sub reg, reg, reg mul reg, reg, reg store reg, address There are three registers r1, r2, r3, each arithmetic instructions takes the left operand from the first register, the right operand from the second register, and places the result in the third register (same as in the book). 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 +bc+d (b) result:= a*b + (C-d)
