2009-05-31Initial infrastructure for class template partial specialization. HereDouglas Gregor
we have the basics of declaring and storing class template partial specializations, matching class template partial specializations at instantiation time via (limited) template argument deduction, and using the class template partial specialization's pattern for instantiation. This patch is enough to make a simple is_pointer type trait work, but not much else. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72662 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-28Introduced DeclContext::isDependentContext, which determines whether aDouglas Gregor
given DeclContext is dependent on type parameters. Use this to properly determine whether a TagDecl is dependent; previously, we were missing the case where the TagDecl is a local class of a member function of a class template (phew!). Also, make sure that, when we instantiate declarations within a member function of a class template (or a function template, eventually), that we add those declarations to the "instantiated locals" map so that they can be found when instantiating declaration references. Unfortunately, I was not able to write a useful test for this change, although the assert() that fires when uncommenting the FIXME'd line in test/SemaTemplate/instantiate-declref.cpp tells the "experienced user" that we're now doing the right thing. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72526 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-24Eliminate Sema::ObjCImplementations, relying instead on name lookup. What's ↵Douglas Gregor
good for uniformity is good for PCH (or is it the other way around?). As part of this, make ObjCImplDecl inherit from NamedDecl (since ObjCImplementationDecls now need to have names so that they can be found). This brings ObjCImplDecl very, very close to ObjCContainerDecl; we may be able to merge them soon. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69941 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-10Various minor fixes to PCH reading and writing, with generalDouglas Gregor
cleanup. Aside from a minor tweak to the PCH file format, no functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68793 91177308-0d34-0410-b5e6-96231b3b80d8
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

2009-02-25Perform additional semantic checking of class templateDouglas Gregor
specializations. In particular: - Make sure class template specializations have a "template<>" header, and complain if they don't. - Make sure class template specializations are declared/defined within a valid context. (e.g., you can't declare a specialization std::vector<MyType> in the global namespace). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65476 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-20optimize the 'StoredDeclsMap' for the common case where there is Chris Lattner
exactly one decl with a specific name in a specific context. This avoids a bunch of malloc traffic and shrinks StoredDeclsMap to hold one pointer instead of 3 words (for a std::vector). This speeds up -fsyntax-only on cocoa.h with PTH by ~7.3%. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65103 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-17Implement basic parsing and semantic analysis for explicitDouglas Gregor
specialization of class templates, e.g., template<typename T> class X; template<> class X<int> { /* blah */ }; Each specialization is a different *Decl node (naturally), and can have different members. We keep track of forward declarations and definitions as for other class/struct/union types. This is only the basic framework: we still have to deal with checking the template headers properly, improving recovery when there are failures, handling nested name specifiers, etc. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64848 91177308-0d34-0410-b5e6-96231b3b80d8
