* Add a few more tests for casts.Eli Friedman2013-06-201-0/+3

* PR15132: Replace "address expression must be an lvalue or a functionRichard Smith2013-02-021-1/+1
| | | | | | | | | | | | | | designator" diagnostic with more correct and more human-friendly "cannot take address of rvalue of type 'T'". For the case of & &T::f, provide a custom diagnostic, rather than unhelpfully saying "cannot take address of rvalue of type '<overloaded function type>'". For the case of &array_temporary, treat it just like a class temporary (including allowing it as an extension); the existing diagnostic wording for the class temporary case works fine. llvm-svn: 174262
* Implement final piece of DR963 and also DR587:Richard Smith2012-08-081-1/+3
| | | | | | | | | | | A conditional operator between glvalues of types cv1 T and cv2 T produces a glvalue if the expressions are of the same value kind and one of cv1 and cv2 is a subset of the other. A conditional operator between two null pointer constants is permitted if one of them is of type std::nullptr_t. llvm-svn: 161476

| | | | | | | C++11 or just C++17, restrict the set of null pointer constants in C++11 mode back to those which were considered null in C++98. llvm-svn: 150510

* Audit and finish the implementation of C++0x nullptr, fixing twoDouglas Gregor2011-05-211-0/+57
| | | | | | | | | | | | | | minor issues along the way: - Non-type template parameters of type 'std::nullptr_t' were not permitted. - We didn't properly introduce built-in operators for nullptr ==, !=, <, <=, >=, or > as candidate functions . To my knowledge, there's only one (minor but annoying) part of nullptr that hasn't been implemented: catching a thrown 'nullptr' as a pointer or pointer-to-member, per C++0x [except.handle]p4. llvm-svn: 131813

| | | | | | | | small bug fixes in SemaInit, switch over SemaDecl to use it more often, and change a bunch of diagnostics which are different with the new initialization code. llvm-svn: 91767
* Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.Daniel Dunbar2009-12-151-1/+1
| | | | | | | | | - This is designed to make it obvious that %clang_cc1 is a "test variable" which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it can be useful to redefine what gets run as 'clang -cc1' (for example, to set a default target). llvm-svn: 91446
