2009-06-30De-ASTContext-ify DeclContext.Argyrios Kyrtzidis
Remove ASTContext parameter from DeclContext's methods. This change cascaded down to other Decl's methods and changes to call sites started "escalating". Timings using pre-tokenized "cocoa.h" showed only a ~1% increase in time run between and after this commit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74506 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-25Improved semantic analysis and AST respresentation for functionDouglas Gregor
templates. For example, this now type-checks (but does not instantiate the body of deref<int>): template<typename T> T& deref(T* t) { return *t; } void test(int *ip) { int &ir = deref(ip); } Specific changes/additions: * Template argument deduction from a call to a function template. * Instantiation of a function template specializations (just the declarations) from the template arguments deduced from a call. * FunctionTemplateDecls are stored directly in declaration contexts and found via name lookup (all forms), rather than finding the FunctionDecl and then realizing it is a template. This is responsible for most of the churn, since some of the core declaration matching and lookup code assumes that all functions are FunctionDecls. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74213 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-25Instantiation for member classes of class templates. Note that onlyDouglas Gregor
the declarations of member classes are instantiated when the owning class template is instantiated. The definitions of such member classes are instantiated when a complete type is required. This change also introduces the injected-class-name into a class template specialization. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67707 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-11Eliminate CXXClassVarDecl. It doesn't add anythingDouglas Gregor
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66696 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-03Implement the basics of implicit instantiation of class templates, inDouglas Gregor
response to attempts to diagnose an "incomplete" type. This will force us to use DiagnoseIncompleteType more regularly (rather than looking at isIncompleteType), but that's also a good thing. Implicit instantiation is still very simplistic, and will create a new definition for the class template specialization (as it should) but it only actually instantiates the base classes and attaches those. Actually instantiating class members will follow. Also, instantiate the types of non-type template parameters before checking them, allowing, e.g., template<typename T, T Value> struct Constant; to work properly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65924 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
2009-02-17Added ClassTemplateSpecializationDecl, which is a subclass ofDouglas Gregor
CXXRecordDecl that is used to represent class template specializations. These are canonical declarations that can refer to either an actual class template specialization in the code, e.g., template<> class vector<bool> { }; or to a template instantiation. However, neither of these features is actually implemented yet, so really we're just using (and uniqing) the declarations to make sure that, e.g., A<int> is a different type from A<float>. Note that we carefully distinguish between what the user wrote in the source code (e.g., "A<FLOAT>") and the semantic entity it represents (e.g., "A<float, int>"); the former is in the sugared Type, the latter is an actual Decl. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64716 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-27Remove many references to ASTContext::getAllocator(), replacing them with ↵Steve Naroff
calls to the recently added placement new (which uses ASTContext's allocator for memory). Also added ASTContext::Deallocate(). This will simplify runtime replacement of ASTContext's allocator. Keeping the allocator private (and removing getAllocator() entirely) is also goodness. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63135 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-20Remove ScopedDecl, collapsing all of its functionality into Decl, soDouglas Gregor
that every declaration lives inside a DeclContext. Moved several things that don't have names but were ScopedDecls (and, therefore, NamedDecls) to inherit from Decl rather than NamedDecl, including ObjCImplementationDecl and LinkageSpecDecl. Now, we don't store empty DeclarationNames for these things, nor do we try to insert them into DeclContext's lookup structure. The serialization tests are temporarily disabled. We'll re-enable them once we've sorted out the remaining ownership/serialiazation issues between DeclContexts and TranslationUnion, DeclGroups, etc. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62562 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-08This is a large/messy diff that unifies the ObjC AST's with DeclContext.Steve Naroff
- ObjCContainerDecl's (ObjCInterfaceDecl/ObjCCategoryDecl/ObjCProtocolDecl), ObjCCategoryImpl, & ObjCImplementation are all DeclContexts. - ObjCMethodDecl is now a ScopedDecl (so it can play nicely with DeclContext). - ObjCContainerDecl now does iteration/lookup using DeclContext infrastructure (no more linear search:-) - Removed ASTContext argument to DeclContext::lookup(). It wasn't being used and complicated it's use from an ObjC AST perspective. - Added Sema::ProcessPropertyDecl() and removed Sema::diagnosePropertySetterGetterMismatch(). - Simplified Sema::ActOnAtEnd() considerably. Still more work to do. - Fixed an incorrect casting assumption in Sema::getCurFunctionOrMethodDecl(), now that ObjCMethodDecl is a ScopedDecl. - Removed addPropertyMethods from ObjCInterfaceDecl/ObjCCategoryDecl/ObjCProtocolDecl. This passes all the tests on my machine. Since many of the changes are central to the way ObjC finds it's methods, I expect some fallout (and there are still a handful of FIXME's). Nevertheless, this should be a step in the right direction. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@61929 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-07Finished semantic analysis of anonymous unions in C++.Douglas Gregor
Duplicate-member checking within classes is still a little messy, and anonymous unions are still completely broken in C. We'll need to unify the handling of fields in C and C++ to make this code applicable in both languages. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@61878 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-05PODness and Type TraitsSebastian Redl
Make C++ classes track the POD property (C++ [class]p4) Track the existence of a copy assignment operator. Implicitly declare the copy assignment operator if none is provided. Implement most of the parsing job for the G++ type traits extension. Fully implement the low-hanging fruit of the type traits: __is_pod: Whether a type is a POD. __is_class: Whether a type is a (non-union) class. __is_union: Whether a type is a union. __is_enum: Whether a type is an enum. __is_polymorphic: Whether a type is polymorphic (C++ [class.virtual]p1). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@61746 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-05Introduce support for "transparent" DeclContexts, which areDouglas Gregor
DeclContexts whose members are visible from enclosing DeclContexts up to (and including) the innermost enclosing non-transparent DeclContexts. Transparent DeclContexts unify the mechanism to be used for various language features, including C enumerations, anonymous unions, C++0x inline namespaces, and C++ linkage specifications. Please refer to the documentation in the Clang internals manual for more information. Only enumerations and linkage specifications currently use transparent DeclContexts. Still to do: use transparent DeclContexts to implement anonymous unions and GCC's anonymous structs extension, and, later, the C++0x features. We also need to tighten up the DeclContext/ScopedDecl link to ensure that every ScopedDecl is in a single DeclContext, which will ensure that we can then enforce ownership and reduce the memory footprint of DeclContext. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@61735 91177308-0d34-0410-b5e6-96231b3b80d8
