2013-02-02PR15132: Replace "address expression must be an lvalue or a functionRichard Smith
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174262 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-08Implement final piece of DR963 and also DR587:Richard Smith
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@161476 91177308-0d34-0410-b5e6-96231b3b80d8

2011-05-21Audit and finish the implementation of C++0x nullptr, fixing twoDouglas Gregor
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@131813 91177308-0d34-0410-b5e6-96231b3b80d8

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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91767 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-15Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.Daniel Dunbar
- 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). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91446 91177308-0d34-0410-b5e6-96231b3b80d8
