In writing clang-tidy checks, I've had to do re-lexing a number of times and personally I find it to be a complete PITA and very easy to get wrong, plus it results in many review iterations because of all the ways that StringRef enters the picture, whether you're using the plain lexer or the raw lexer, SourceRange or CharSourceRange, yadda yadda yadda. I thought the whole point of the AST was to do this work **once** and store the results of the work for tools. http://reviews.llvm.org/D16012 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
