[cfe-dev] variability-aware lexer/parser

[riya khanna via cfe-dev]

Hi,

Is it possible to make the lexer and parser in clang a variability-aware?
For example, if a C/C++ program contains a #ifdef, #else, #endif sequence,
can clang generate AST with conditional nodes? How much effort would be
needed?

Thanks,
-Riya
