Compiler Construction Using Flex And Bison

Yacc and Bison are tools for generating parsers: programs which recognize
the structure grammatical structure of programs. Bison is a faster version
of Yacc. In this chapter, Yacc/Bison refers to either of these tools. The
sections on Yacc/Bison are a condensation and extension of the document
“BISON the Yacc-compatible Parser Generator” by Charles Donnelly and
Richard Stallman.
