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

2009-07-29[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.

2009-07-24Template instantiation for static data members that are defined out-of-line.Douglas Gregor
Note that this also fixes a bug that affects non-template code, where we were not treating out-of-line static data members are "file-scope" variables, and therefore not checking their initializers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@77002 91177308-0d34-0410-b5e6-96231b3b80d8

Enhance test case to cover 'isa' access on interface types (clang produces an error, GCC produces a warning). Still need back-end CodeGen for ObjCIsaExpr. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76979 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-205 cleanups to ObjCObjectPointerType work:Steve Naroff
- Remove Sema::CheckPointeeTypesForAssignment(), a temporary API I added to ease migration to ObjCObjectPointerType. Convert Sema::CheckAssignmentConstraints() to no longer depend on the temporary API. - Sema::ConvertDeclSpecToType(): Replace a couple FIXME's with an important comment/example. - Sema::GetTypeForDeclarator(): Get the protocol's from the interface, NOT the declspec (to support the following C typedef idiom: "typedef C<P> T; T *obj"). - Sema::ObjCQualifiedIdTypesAreCompatible(): Removed some dead code. - ASTContext::getObjCEncodingForTypeImpl(): Some minor cleanups. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76443 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

2009-07-16Add 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

2009-07-16Avoid crashing for the enclosed test case.Steve Naroff
This is fallout from the recent ObjCObjectPointerType rework. I'll work on fixing this tomorrow. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@75870 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

2009-07-10This 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

2009-07-01Rework Sema::CheckConditionalOperands(). No functionality change.Steve Naroff
This was necessary to simplify some other changes I'm making (wrt ObjC type cleanups). The idea is to separate the constraint checks for block pointers, ObjC pointers, and C pointers (the previous code combined them into one clause). Note: This routine will be further simplified when I integrate the ObjC type cleanups (forthcoming). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74604 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-30When recursively instantiating function templates, keep track of theDouglas Gregor
instantiation stack so that we provide a full instantiation backtrace. Previously, we performed all of the instantiations implied by the recursion, but each looked like a "top-level" instantiation. The included test case tests the previous fix for the instantiation of DeclRefExprs. Note that the "instantiated from" diagnostics still don't tell us which template arguments we're instantiating with. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74540 91177308-0d34-0410-b5e6-96231b3b80d8

Use the "semantic analysis" part when performing template instantiation on a DeclRefExpr, rather than an ad hoc list of rules to construct DeclRefExprs from the instantiation. A test case for this change will come in with a large commit, which illustrates what I was actually trying to work on. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74528 91177308-0d34-0410-b5e6-96231b3b80d8
