2009-05-22Cannot type cast @selector expressions.Fariborz Jahanian
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72284 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-22Representation of and template instantiation for memberDouglas Gregor
expressions. This change introduces another AST node, CXXUnresolvedMemberExpr, that captures member references (x->m, x.m) when the base of the expression (the "x") is type-dependent, and we therefore cannot resolve the member reference yet. Note that our parsing of member references for C++ is still quite poor, e.g., we don't handle x->Base::m or x->operator int. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72281 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-19Template instantiation for array subscript expressions. This was farDouglas Gregor

2009-05-16Avoid calling mergeTypes in C++. I think these are the correct C++ Eli Friedman
alternatives, but please correct me if I'm wrong. I eventually plan to assert in mergeTypes that we aren't in C++ mode because composite types are fundamentally not a part of C++. The remaining callers for code in the regression tests are Sema::WarnConflictingTypedMethods and CodeGenFunction::EmitFunctionProlog; I'm not quite sure what the correct approach is for those callers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@71946 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-04Implement support for comparing pointers with <, >, <=, >=, ==, and !=Douglas Gregor
in C++, taking into account conversions to the "composite pointer type" so that we can compare, e.g., a pointer to a derived class to a pointer to a base class. Also, upgrade the "comparing distinct pointer types" from a warning to an error for C++, since this is clearly an error. Turns out that we hadn't gone through and audited this code for C++, ever.

2009-05-02When determining whether an expression refers to a bit-field, lookDouglas Gregor
