2009-08-24Try to complete a type before looking for conversion functions withinDouglas Gregor
that type. Note that we do not produce a diagnostic if the type is incomplete; rather, we just don't look for conversion functions. Fixes PR4660. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@79919 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-21Implement support for calling member function templates, which involves:Douglas Gregor
- Allowing one to name a member function template within a class template and on the right-hand side of a member access expression. - Template argument deduction for calls to member function templates. - Registering specializations of member function templates (and finding them later). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@79581 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-29Change uses of:Ted Kremenek
Type::getAsReferenceType() -> Type::getAs<ReferenceType>() Type::getAsRecordType() -> Type::getAs<RecordType>() Type::getAsPointerType() -> Type::getAs<PointerType>() Type::getAsBlockPointerType() -> Type::getAs<BlockPointerType>() Type::getAsLValueReferenceType() -> Type::getAs<LValueReferenceType>() Type::getAsRValueReferenceType() -> Type::getAs<RValueReferenceType>() Type::getAsMemberPointerType() -> Type::getAs<MemberPointerType>() Type::getAsReferenceType() -> Type::getAs<ReferenceType>() Type::getAsTagType() -> Type::getAs<TagType>() And remove Type::getAsReferenceType(), etc. This change is similar to one I made a couple weeks ago, but that was partly reverted pending some additional design discussion. With Doug's pending smart pointer changes for Types, it seemed natural to take this approach. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@77510 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-25Implement C++ semantics for C-style and functional-style casts. This ↵Sebastian Redl
regresses Clang extension conversions, like vectors, but allows conversions via constructors and conversion operators. Add custom conversions to static_cast. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@77076 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-23Remove a bunch of FIXME's related to ObjC type checking.Steve Naroff
- Move Sema::ObjCQualifiedIdTypesAreCompatible(), Sema::QualifiedIdConformsQualifiedId(), and a couple helper functions to ASTContext. - Change ASTContext::canAssignObjCInterfaces() to use ASTContext:: ObjCQualifiedIdTypesAreCompatible(). - Tweak several test cases to accommodate the new/improved type checking. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76830 91177308-0d34-0410-b5e6-96231b3b80d8

place. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76274 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-17Per offline discussion with Steve Naroff, add back Type::getAsXXXType() methodsTed Kremenek
until Doug Gregor's Type smart pointer code lands (or more discussion occurs). These methods just call the new Type::getAs<XXX> methods, so we still have reduced implementation redundancy. Having explicit getAsXXXType() methods makes it easier to set breakpoints in the debugger. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76193 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-17Replaced Type::getAsLValueReferenceType(), Type::getAsRValueReferenceType(), ↵Ted Kremenek

2009-07-17Replace Type::getAsReferenceType() with Type::getAs<ReferenceType>().Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76132 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-16Add member template 'Type::getAs<T>', which converts a Type* to a respective T*.Ted Kremenek
This method is intended to eventually replace the individual Type::getAsXXXType<> methods. The motivation behind this change is twofold: 1) Reduce redundant implementations of Type::getAsXXXType() methods. Most of them are basically copy-and-paste. 2) By centralizing the implementation of the getAs<Type> logic we can more smoothly move over to Doug Gregor's proposed canonical type smart pointer scheme. Along with this patch: a) Removed 'Type::getAsPointerType()'; now clients use getAs<PointerType>. b) Removed 'Type::getAsBlockPointerTypE()'; now clients use getAs<BlockPointerType>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76098 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-16Remove ASTContext::isObjCObjectPointerType().Steve Naroff
Convert all clients to use the new predicate on Type. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76076 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-15Implement the ObjC pseudo built-in types as clang "BuiltinType's". I say ↵Steve Naroff
pseudo built-in types, since Sema still injects a typedef for recognition (i.e. they aren't truly built-ins from a parser perspective). This removes the static data/methods on ObjCObjectPointerType while preserving the nice API (no need to fiddle with ASTContext:-). This patch also adds Type::isObjCBuiltinType(). This should be the last fairly large patch related to recrafting the ObjC type system. The follow-on patches should be fairly small. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@75808 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-14For C++ overloaded operator calls, set the source location of the ↵Argyrios Kyrtzidis
DeclRefExpr to the location of the operator. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@75600 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-10This patch includes a conceptually simple, but very intrusive/pervasive change. Steve Naroff
The idea is to segregate Objective-C "object" pointers from general C pointers (utilizing the recently added ObjCObjectPointerType). The fun starts in Sema::GetTypeForDeclarator(), where "SomeInterface *" is now represented by a single AST node (rather than a PointerType whose Pointee is an ObjCInterfaceType). Since a significant amount of code assumed ObjC object pointers where based on C pointers/structs, this patch is very tedious. It should also explain why it is hard to accomplish this in smaller, self-contained patches. This patch does most of the "heavy lifting" related to moving from PointerType->ObjCObjectPointerType. It doesn't include all potential "cleanups". The good news is additional cleanups can be done later (some are noted in the code). This patch is so large that I didn't want to include any changes that are purely aesthetic. By making the ObjC types truly built-in, they are much easier to work with (and require fewer "hacks"). For example, there is no need for ASTContext::isObjCIdStructType() or ASTContext::isObjCClassStructType()! We believe this change (and the follow-up cleanups) will pay dividends over time. Given the amount of code change, I do expect some fallout from this change (though it does pass all of the clang tests). If you notice any problems, please let us know asap! Thanks. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@75314 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-08Implement template argument deduction when taking the address of aDouglas Gregor
