2 Compiler Slide Pdf Parsing Reserved Word The document discusses the role of the lexical analyzer as the first phase of a compiler. it reads input characters, groups them into lexemes, and produces tokens. the tokens are passed to the parser for syntax analysis. the lexical analyzer identifies identifiers and enters them into the symbol table. it interacts with the parser by returning the next token upon request. the lexical analyzer. Acknowledgement these slides borrow liberal portions of text verbatim from antony l. hosking @ purdue, jens palsberg @ ucla and the dragon book.
Compiler Pdf Parsing Compiler This tutorial explains how to fix uncaught syntaxerror: unexpected reserved word 'await' in javascript. The parser also provides a structuring mechanism that divides the task of code generation into bits and pieces determined by the individual nonterminals and produc tion rules.

The document is a lab manual for compiler design, detailing experiments on implementing a lexical analyzer, predictive parser, generating three address code, and designing an slr(1) bottom up parser. each experiment includes problem statements, aims, algorithms, source code, and expected outputs, along with viva questions for assessment. the manual serves as a practical guide for students to. This improves compiler efficiency, as specialized techniques can be used for each task separately. compiler portability is enhanced because the lexical analyzer can handle device specific input peculiarities, isolating them from the main parsing logic, making the compiler easier to adapt to different systems. 7 f tokens, patterns & lexemes.
