Abstract syntax trees are data structures widely used in compilers to represent the structure of program code An ast is usually the result of the syntax analysis phase of a compiler It often serves as an intermediate representation of the program through several stages that the compiler requires, and has a strong affect on the final output of the compiler. It also manages the symbol table, a data structure mapping each symbol in the source code to associated information such as location, type and scope While the frontend can be a single monolithic function or program, as in a scannerless parser, it was traditionally implemented and analyzed as several phases, which may execute sequentially or. Principles, techniques, and tools[1] is a computer science textbook by alfred v
Lam, ravi sethi, and jeffrey d Ullman about compiler construction for programming languages First published in 1986, it is widely regarded as the classic definitive compiler technology text [2] it is known as the dragon book to generations of computer scientists [3][4] as its cover.
