2009-01-06rename tok::annot_qualtypename -> tok::annot_typename, which is bothChris Lattner
shorter and more accurate. The type name might not be qualified. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@61788 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-05PODness and Type TraitsSebastian Redl
Make C++ classes track the POD property (C++ [class]p4) Track the existence of a copy assignment operator. Implicitly declare the copy assignment operator if none is provided. Implement most of the parsing job for the G++ type traits extension. Fully implement the low-hanging fruit of the type traits: __is_pod: Whether a type is a POD. __is_class: Whether a type is a (non-union) class. __is_union: Whether a type is a union. __is_enum: Whether a type is an enum. __is_polymorphic: Whether a type is polymorphic (C++ [class.virtual]p1). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@61746 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-05remove optimization to avoid looking ahead for cases like ::foo. ThisChris Lattner
isn't worth the complexity and the code already does a ton of lookahead. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@61671 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-04sink the call to TryAnnotateTypeOrScopeToken in Chris Lattner

2008-12-23Don't explicitly represent OverloadedFunctionDecls withinDouglas Gregor
DeclContext. Instead, just keep the list of currently-active declarations and only build the OverloadedFunctionDecl when we absolutely need it. This is a half-step toward eliminating the need to explicitly build OverloadedFunctionDecls that store sets of overloaded functions. This was suggested by Argiris a while back, and it's a good thing for several reasons: first, it eliminates the messy logic that currently tries to keep the OverloadedFunctionDecl in sync with the declarations that are being added. Second, it will (eventually) eliminate the need to allocate memory for overload sets, which could help performance. Finally, it helps set us up for when name lookup can return multiple (possibly ambiguous) results, as can happen with lookup of class members in C++. Next steps: make the IdentifierResolver store overloads as separate entries in its list rather than replacing them with an OverloadedFunctionDecl now, then see how far we can go toward eliminating OverloadedFunctionDecl entirely. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@61357 91177308-0d34-0410-b5e6-96231b3b80d8

2008-12-06Add support for calls to dependent names within templates, e.g.,Douglas Gregor
template<typename T> void f(T x) { g(x); // g is a dependent name, so don't even bother to look it up g(); // error: g is not a dependent name } Note that when we see "g(", we build a CXXDependentNameExpr. However, if none of the call arguments are type-dependent, we will force the resolution of the name "g" and replace the CXXDependentNameExpr with its result. GCC actually produces a nice error message when you make this mistake, and even offers to compile your code with -fpermissive. I'll do the former next, but I don't plan to do the latter. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@60618 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-23Convert IdentifierInfo's to be printed the same as DeclarationNames Chris Lattner
with implicit quotes around them. This has a bunch of follow-on effects and requires tweaking to a whole lot of code. This causes a regression in two tests (xfailed) by causing it to emit things like: Line 10: duplicate interface declaration for category 'MyClass1' ('Category1') instead of: Line 10: duplicate interface declaration for category 'MyClass1(Category1)' I will fix this in a follow-up commit. As part of this, I had to start switching stuff to use ->getDeclName() instead of Decl::getName() for consistency. This is good, but I was planning to do this as an independent patch. There will be several follow-on patches to clean up some of the mess, but this patch is already too big. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59917 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-19Added operator overloading for unary operators, post-increment, andDouglas Gregor
post-decrement, including support for generating all of the built-in operator candidates for these operators. C++ and C have different rules for the arguments to the builtin unary '+' and '-'.

2008-11-06Initial, rudimentary implementation of operator overloading for binaryDouglas Gregor
operators. For example, one can now write "x + y" where x or y is a class or enumeration type, and Clang will perform overload resolution for "+" based on the overloaded operators it finds. The other kinds of overloadable operators in C++ will follow this same approach. Three major issues remain: 1) We don't find member operators 2) Since we don't have user-defined conversion operators, we can't call any of the built-in overloaded operators in C++ [over.built]. 3) Once we've done the semantic checks, we drop the overloaded operator on the floor; it doesn't get into the AST at all. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@58821 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-06Parsing, ASTs, and semantic analysis for the declaration of overloadedDouglas Gregor
