[cfe-dev] preprocessor hacking

[Nikola Smiljanic]

If you invoke clang as a driver (as in clang test.c) it will spawn a new
process for the frontend (that lexes, preprocesses, parses etc.) and a new
process for linker and assembler. To debug the frontend itself (and not the
driver) pass -cc1 (as in clang -cc1 test.c).

Not sure where you'd like to break, but have a look at Lexer.cpp and
Preprocessor.cpp and pick a method. Constructor might be a good place to
start...
