A compiler designing project built using flex(lex file) and bison(yacc file). - FaiasPromit/Personal-language-Compiler-design-Project
Jonathan's Optimizing and Extensible C Compiler (pronounced "joke"), called as such because the name, just like any attempt to use the compiler in place of an industrial strength one like gcc or clang, is a poorly written joke. c bison flex compiler optimization ast lex control-flow lexical...
Each utility is explained in a chapter that covers basic usage and simple, stand-alone applications. You'll learn how to implement a full SQL grammar, with full sample code. Major MS-DOS and Unix versions of lex and yacc are explored in depth. Also covers Bison and Flex. lex & yacc ...
* * If the compilergenerates a YYPARSERNAMEerror thenyou have not declared * the name of theparser.The easiest way to do this is to use a name * declaration. This is placed inthe declarations of your YACC * source file and is introduced with the %name keyword For instance,...
make tinylex compatible with flex/lex. (Tinylex is only subset of flex/lex now. And many auxiliary functions or flags aren't supported, such as yywrap/yymore/yyrestart) 3. support multi-line accept action string (Maybe I need a internal C parser.) 4. support recursive macro definition +...
