2009-08-15Don't perform integer promotions on the operand to a cast; this Eli Friedman
simplifies the AST, and can matter in some rare cases involving casts to vector types. Patch by Enea Zaffanella. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@79126 91177308-0d34-0410-b5e6-96231b3b80d8

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

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

2009-07-15Implement 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
