2009-09-24Refactor the representation of qualifiers to bring ExtQualType out of theJohn McCall
Type hierarchy. Demote 'volatile' to extended-qualifier status. Audit our use of qualifiers and fix a few places that weren't dealing with qualifiers quite right; many more remain. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82705 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-21Change all the Type::getAsFoo() methods to specializations of Type::getAs().John McCall
Several of the existing methods were identical to their respective specializations, and so have been removed entirely. Several more 'leaf' optimizations were introduced. The getAsFoo() methods which imposed extra conditions, like getAsObjCInterfacePointerType(), have been left in place. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82501 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-09Initial stab at implement dependent member references to memberDouglas Gregor
templates, e.g., x.template get<T> We can now parse these, represent them within an UnresolvedMemberExpr expression, then instantiate that expression node in simple cases. This allows us to stumble through parsing LLVM's Casting.h. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@81300 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-05Basic support for representing elaborated type specifiersJohn McCall
directly in the AST. The current thinking is to create these only in C++ mode for efficiency. But for now, they're not being created at all; patch to follow. This will let us do things like verify that tags match during template instantation, as well as signal that an elaborated type specifier was used for clients that actually care. Optimally, the TypeLoc hierarchy should be adjusted to carry tag location information as well. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@81057 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-29Improve instantiation of UnresolvedUsingDecls.Anders Carlsson
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@80434 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-25Improve support for out-of-line definitions of nested templates andDouglas Gregor
their members, including member class template, member function templates, and member classes and functions of member templates. To actually parse the nested-name-specifiers that qualify the name of an out-of-line definition of a member template, e.g., template<typename X> template<typename Y> X Outer<X>::Inner1<Y>::foo(Y) { return X(); } we need to look for the template names (e.g., "Inner1") as a member of the current instantiation (Outer<X>), even before we have entered the scope of the current instantiation. Since we can't do this in general (i.e., we should not be looking into all dependent nested-name-specifiers as if they were the current instantiation), we rely on the parser to tell us when it is parsing a declaration specifier sequence, and, therefore, when we should consider the current scope specifier to be a current instantiation. Printing of complicated, dependent nested-name-specifiers may be somewhat broken by this commit; I'll add tests for this issue and fix the problem (if it still exists) in a subsequent commit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@80044 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-19Introduce DeclaratorDecl and pass DeclaratorInfo through the Decl/Sema ↵Argyrios Kyrtzidis
interfaces. DeclaratorDecl contains a DeclaratorInfo* to keep type source info. Subclasses of DeclaratorDecl are FieldDecl, FunctionDecl, and VarDecl. EnumConstantDecl still inherits from ValueDecl since it has no need for DeclaratorInfo. Decl/Sema interfaces accept a DeclaratorInfo as parameter but no DeclaratorInfo is created yet. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@79392 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-19Introduce DeclaratorInfo and TypeLoc, intended to be used for storing and ↵Argyrios Kyrtzidis
reading source information for types. DeclaratorInfo will contain a flat memory block for source information about a type that came out of a declarator. TypeLoc and its subclasses will be used by clients as wrappers to "traverse" the memory block and read the information. Both DeclaratorInfo and TypeLoc are not utilized in this commit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@79391 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-17Initial patch to support definitions of id and Class from headers in ↵David Chisnall
Objective-C code. This currently breaks test/SemaObjC/id-isa-ref.m and issues some spurious warnings when you attempt to assign a struct objc_class* value to a Class variable. The test case probably should fail as it's written, because without the definition of Class the compiler should not assume struct objc_class* is a valid receiver type, but it's left broken because it would be nice if we could get that passing too for the special case of isa. Approved by snaroff. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@79248 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-15Fix for PR4721: adjust CodeGen and ASTContext so that we have a Eli Friedman
consistent model for handling size expressions for VLAs. The model is essentially as follows: VLA types own their associated expression. In some cases, we need to create multiple VLA types to represent a given VLA (for canonical types, or qualifiers on array types, or type merging). If we need to create multiple types based off of the same VLA declaration, we use the new refcounting functionality so they can all own the expression. The VLASizeMap in CodeGenFunction then uses the size expression to identify the group of VLA types based off of the same original declaration. I'm not particularly attached to the VLA types owning the expression, but we're stuck with at least until someone comes up with a way to walk the VLA expressions for a declaration. I did the parallel fix in ASTContext for DependentSizedArrayType, but I haven't really looked closely at it, so there might still be issues there. I'll clean up the code duplication in ASTContext in a followup commit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@79071 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-29[llvm up]Douglas Gregor
A template name can refer to a set of overloaded function templates. Model this in TemplateName, which can now refer to an OverloadedFunctionDecl that contains function templates.
