Andrzej Kotulski 5a07f767bb Handle assignment operations correctly ... Summary: public C++ assignment operation result is lvalue, while in C it was rvalue. This leads to different AST produced by clang for then same code! Use language information from clang (`-x` flag) to distinguish these cases. More specifically, let's look at following code: int r; int f = (r = 3); // type of (r = 3) expression: // C/objC -> int rvalue // C++/objC++ -> int lvalue Existing code did extra dereference because it was rvalue in C and there was no cast afterwards in C++ there will be extra LValueToRvalue cast when neccesary so we don't have to do extra dereference manually Reference: http://en.cppreference.com/w/c/language/value_category (search for 'assignment and compound assignment operators') NOTE: AST output doesn't change when something is hidden behind `extern "C"`, so we should use global language information Reviewed By: ddino Differential Revision: D2549866 fb-gh-sync-id: b193b11		10 years ago
