Hey Asma,
yes, in older versions of gcc generator tools like flex/bison were used to parse the source code, but this was changed with newer versions. Now, GCC uses hand-written lexer and parsers (recursive descent parser). So for C, you need to look for gcc-x.y.z/gcc/c-parser.c.
Hope that helps,
Andi

Subject: gcc analyze tools
Hello,
to analyze the source code, I thought that gcc uses flex and bison. but I red
yesterday in a presentation done on 2008 that gcc did not use those old tools.
I tried to verify and I find that for c++ in the cp directory there is lex.c it
means that gcc still use flex bison to parse source code;
did someone has as better knowledges about gcc analysis and can give me a
better idea about which tools are used by gcc to parse source code?
thank you very much.
Asma
