out of Sema, since it was only there as a historical artifact. Patch by

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.
llvm-svn: 79392
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.

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.

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.

for those extra-esoteric cases. Not that any two given C++ compilers
agree on this test case, but this change gives us a strong definition
of equivalent types.
llvm-svn: 77664
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.

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. This removes
an unspeakable hack in Sema::isTemplateName.
llvm-svn: 77488
template arguments, as in template specialization types. This permits
matching out-of-line definitions of members for class templates that
involve non-type template parameters.
llvm-svn: 77462
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.

- 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.

an interface/category with its implementation (if one exists).
- Introduce ObjCInterfaceDecl::get/setImplementation() and ObjCCategoryDecl::get/setImplementation() that use the above methods.
- Add a compiler error for when a category is reimplemented.
llvm-svn: 76508
- 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.

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.
llvm-svn: 76193
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>.
llvm-svn: 76098
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.
