Handout written by maggie Johnson and revised by me Three address code Three-address code(tac) will be the intermediate representation used in our Decaf compiler. It is

Semantic analysis Parsing only verifies that the program consists of tokens arranged in a syntactically-valid combination, we now move on to semantic analysis, where we delve deeper to check whether they form a sensible set of instructions in the programming language

TAC Three address code Three-address code (tac) will be the intermediate representation used in our Decaf compiler. It is essentially a generic assembly language that falls in the lower-end of the mid-level IRs. Many compilers use an IR similar to TAC. It is a sequence of instructions, each of which can have at
