Three-Address Statements Binary Operator: op y,z,result or result :=y op z where op is a binary arithmetic or logical operator.This binary operator is applied to y and z,and the result of the operation is stored in result. Ex: add a,b,c gt a,b,c addr a,b,c addi a,b,c Unary Operator: op y,,result or result :op y where op is a unary arithmetic or logical operator.This unary operator is applied to y, and the result of the operation is stored in result. Ex: uminus ar c not arc inttoreal a,,c CS308 Compiler Theory 4Three-Address Statements Binary Operator: op y,z,result or result := y op z w here op i bi ith ti l i l t Thi bi t i li d t is a binary arithmetic or logica l opera tor.
