Semantic Analysis

Semantic Analysis. Chapter 4. Role of Semantic Analysis. Following parsing, the next two phases of the "typical" compiler are semantic analysis (intermediate) code generation The principal job of the semantic analyzer is to enforce static semantic rules

Abstract Syntax Tree (AST)

Abstract Syntax Tree (AST). The parse tree contains too much detail e.g. unnecessary terminals such as parentheses depends heavily on the structure of the grammar e.g. intermediate non-terminals Idea: strip the unnecessary parts of the tree, simplify it.

Attribute Grammar Professor Yihjia Tsai Tamkang University

Attribute Grammar Professor Yihjia Tsai Tamkang University. Beyond syntax analysis. An identifier named x has been recognized. Is x a scalar, array or function? How big is x? If x is a function, how many and what type of arguments does it take? Is x declared before being used?

Static semantics

Static semantics. Semantic checking which can be done at compile-time Type-compatibility int can be assigned to double (type coercion) double cannot be assigned to int without explicit type cast Can be captured in grammar, but only at expense of larger, more complex grammar.
