2009-04-09Implementation of pre-compiled headers (PCH) based on lazyDouglas Gregor
de-serialization of abstract syntax trees. PCH support serializes the contents of the abstract syntax tree (AST) to a bitstream. When the PCH file is read, declarations are serialized as-needed. For example, a declaration of a variable "x" will be deserialized only when its VarDecl can be found by a client, e.g., based on name lookup for "x" or traversing the entire contents of the owner of "x". This commit provides the framework for serialization and (lazy) deserialization, along with support for variable and typedef declarations (along with several kinds of types). More declarations/types, along with important auxiliary structures (source manager, preprocessor, etc.), will follow. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68732 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-31Fix a problem in ASTContext::addRecordToClass handling forward declarations.Chris Lattner
In a case like: @class foo; foo *P; addRecordToClass was making an empty shadow struct for the foo interface and completing it. Later when an: @interface foo ... @endif foo *Q; was seen, ASTContext::addRecordToClass would think that foo was already laid out and not lay out the definition. This fixes it to create a forward declared struct the first time around, then complete it when the definition is seen. Note that this causes two tests to regress, because something is trying to get the size of the forward declared structs returned by this. Previously, this would end up getting a size of zero but now it properly dies. I'm not sure what the right solution is for this, so I xfailed the tests. Fariborz, please take a look at this. The testcase in rdar://6676794 now gets farther, but dies later because the objc ivar is not assigned a field number. As an aside, I really don't like the fact that the objc front-end is creating shadow C structs for ObjC types. This seems like an implementation detail of the code generator that could be fixed by better factoring of the extant code. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68106 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-31Parsing and AST representation for dependent template names that occurDouglas Gregor
within nested-name-specifiers, e.g., for the "apply" in typename MetaFun::template apply<T1, T2>::type At present, we can't instantiate these nested-name-specifiers, so our testing is sketchy. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68081 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-30Improve the representation of template names in the AST. ThisDouglas Gregor
representation handles the various ways in which one can name a template, including unqualified references ("vector"), qualified references ("std::vector"), and dependent template names ("MetaFun::template apply"). One immediate effect of this change is that the representation of nested-name-specifiers in type names for class template specializations (e.g., std::vector<int>) is more accurate. Rather than representing std::vector<int> as std::(vector<int>) we represent it as (std::vector)<int> which more closely follows the C++ grammar. Additionally, templates are no longer represented as declarations (DeclPtrTy) in Parse-Sema interactions. Instead, I've introduced a new OpaquePtr type (TemplateTy) that holds the representation of a TemplateName. This will simplify the handling of dependent template-names, once we get there. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68074 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-27Initial implementation of parsing, semantic analysis, and templateDouglas Gregor
instantiation for C++ typename-specifiers such as typename T::type The parsing of typename-specifiers is relatively easy thanks to annotation tokens. When we see the "typename", we parse the typename-specifier and produce a typename annotation token. There are only a few places where we need to handle this. We currently parse the typename-specifier form that terminates in an identifier, but not the simple-template-id form, e.g., typename T::template apply<U, V> Parsing of nested-name-specifiers has a similar problem, since at this point we don't have any representation of a class template specialization whose template-name is unknown. Semantic analysis is only partially complete, with some support for template instantiation that works for simple examples. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67875 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-26Revamp our representation of C++ nested-name-specifiers. We now have aDouglas Gregor
uniqued representation that should both save some memory and make it far easier to properly build canonical types for types involving dependent nested-name-specifiers, e.g., "typename T::Nested::type". This approach will greatly simplify the representation of CXXScopeSpec. That'll be next. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67799 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-19Introduce a representation for types that we referred to via aDouglas Gregor
qualified name, e.g., foo::x so that we retain the nested-name-specifier as written in the source code and can reproduce that qualified name when printing the types back (e.g., in diagnostics). This is PR3493, which won't be complete until finished the other tasks mentioned near the end of this commit. The parser's representation of nested-name-specifiers, CXXScopeSpec, is now a bit fatter, because it needs to contain the scopes that precede each '::' and keep track of whether the global scoping operator '::' was at the beginning. For example, we need to keep track of the leading '::', 'foo', and 'bar' in ::foo::bar::x The Action's CXXScopeTy * is no longer a DeclContext *. It's now the opaque version of the new NestedNameSpecifier, which contains a single component of a nested-name-specifier (either a DeclContext * or a Type *, bitmangled). The new sugar type QualifiedNameType composes a sequence of NestedNameSpecifiers with a representation of the type we're actually referring to. At present, we only build QualifiedNameType nodes within Sema::getTypeName. This will be extended to other type-constructing actions (e.g., ActOnClassTemplateId). Also on the way: QualifiedDeclRefExprs will also store a sequence of NestedNameSpecifiers, so that we can print out the property nested-name-specifier. I expect to also use this for handling dependent names like Fibonacci<I - 1>::value. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67265 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-09Implement template instantiation for ClassTemplateSpecializationTypes,Douglas Gregor
such as replacing 'T' in vector<T>. There are a few aspects to this: - Extend TemplateArgument to allow arbitrary expressions (an Expr*), and switch ClassTemplateSpecializationType to store TemplateArguments rather than it's own type-or-expression representation. - ClassTemplateSpecializationType can now store dependent types. In that case, the canonical type is another ClassTemplateSpecializationType (with default template arguments expanded) rather than a declaration (we don't build Decls for dependent types). - Split ActOnClassTemplateId into ActOnClassTemplateId (called from the parser) and CheckClassTemplateId (called from ActOnClassTemplateId and InstantiateType). They're smart enough to handle dependent types, now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66509 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-26Create a new TypeNodes.def file that enumerates all of the types,Douglas Gregor
giving them rough classifications (normal types, never-canonical types, always-dependent types, abstract type representations) and making it far easier to make sure that we've hit all of the cases when decoding types. Switched some switch() statements on the type class over to using this mechanism, and filtering out those things we don't care about. For example, CodeGen should never see always-dependent or non-canonical types, while debug info generation should never see always-dependent types. More switch() statements on the type class need to be moved over to using this approach, so that we'll get warnings when we add a new type then fail to account for it somewhere in the compiler. As part of this, some types have been renamed: TypeOfExpr -> TypeOfExprType FunctionTypeProto -> FunctionProtoType FunctionTypeNoProto -> FunctionNoProtoType There shouldn't be any functionality change... git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65591 91177308-0d34-0410-b5e6-96231b3b80d8
