2009-04-22Remove the serialization code that predates precompiledDouglas Gregor
headers. Future approaches to (de-)serializing ASTs will be based on the PCH infrastructure. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69828 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-18FunctionDecl::getBody() is getting an ASTContext argument for use inDouglas Gregor
lazy PCH deserialization. Propagate that argument wherever it needs to be. No functionality change, except that I've tightened up a few PCH tests in preparation. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69406 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-02Resynchronize Decl/VarDecl serialization code with the structuresDouglas Gregor
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68346 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-29Push DeclGroup much farther throughout the compiler. Now the variousChris Lattner
productions (except the already broken ObjC cases like @class X,Y;) in the parser that can produce more than one Decl return a DeclGroup instead of a Decl, etc. This allows elimination of the Decl::NextDeclarator field, and exposes various clients that should look at all decls in a group, but which were only looking at one (such as the dumper, printer, etc). These have been fixed. Still TODO: 1) there are some FIXME's in the code about potentially using DeclGroup for better location info. 2) ParseObjCAtDirectives should return a DeclGroup due to @class etc. 3) I'm not sure what is going on with StmtIterator.cpp, or if it can be radically simplified now. 4) I put a truly horrible hack in ParseTemplate.cpp. I plan to bring up #3/4 on the mailing list, but don't plan to tackle #1/2 in the short term. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68002 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-05Improve the representation of template type parameters. We nowDouglas Gregor
canonicalize by template parameter depth, index, and name, and the unnamed version of a template parameter serves as the canonical. TemplateTypeParmDecl no longer needs to inherit from TemplateParmPosition, since depth and index information is present within the type. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63899 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-02Add a macro-based enumeration of all of the Decl nodes (like we doDouglas Gregor
with Stmt/Expr nodes), and convert some of the more mundane switch-on-all-decl-kinds uses over to use this new file. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63570 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
2009-01-09Replace DeclContext's vector of ScopedDecl pointers with a linked listDouglas Gregor
of ScopedDecls (using the new ScopedDecl::NextDeclInScope pointer). Performance-wise: - It's a net win in memory utilization, since DeclContext is now one pointer smaller than it used to be (std::vectors are typically 3 pointers; we now use 2 pointers) and - Parsing Cocoa.h with -fsyntax-only (with a Release-Asserts Clang) is about 1.9% faster than before, most likely because we no longer have the memory allocations and copying associated with the std::vector. I'll re-enable serialization of DeclContexts once I've sorted out the NextDeclarator/NextDeclInScope question. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62001 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-07Initial implementation of anonymous unions (and, as a GNU extension,Douglas Gregor
structures and classes) in C++. Covers name lookup and the synthesis and member access for the unnamed objects/fields associated with anonymous unions. Some C++ semantic checks are still missing (anonymous unions can't have function members, static data members, etc.), and there is no support for anonymous structs or unions in C. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@61840 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

2008-12-11Unifies the name-lookup mechanisms used in various parts of the ASTDouglas Gregor
and separates lexical name lookup from qualified name lookup. In particular: * Make DeclContext the central data structure for storing and looking up declarations within existing declarations, e.g., members of structs/unions/classes, enumerators in C++0x enums, members of C++ namespaces, and (later) members of Objective-C interfaces/implementations. DeclContext uses a lazily-constructed data structure optimized for fast lookup (array for small contexts, hash table for larger contexts). * Implement C++ qualified name lookup in terms of lookup into DeclContext. * Implement C++ unqualified name lookup in terms of qualified+unqualified name lookup (since unqualified lookup is not purely lexical in C++!) * Limit the use of the chains of declarations stored in IdentifierInfo to those names declared lexically. * Eliminate CXXFieldDecl, collapsing its behavior into FieldDecl. (FieldDecl is now a ScopedDecl). * Make RecordDecl into a DeclContext and eliminates its Members/NumMembers fields (since one can just iterate through the DeclContext to get the fields). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@60878 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-05Representation of template type parameters and non-type templateDouglas Gregor
parameters, with some semantic analysis: - Template parameters are introduced into template parameter scope - Complain about template parameter shadowing (except in Microsoft mode) Note that we leak template parameter declarations like crazy, a problem we'll remedy once we actually create proper declarations for templates. Next up: dependent types and value-dependent/type-dependent expressions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@60597 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-18Extend DeclarationName to support C++ overloaded operators, e.g.,Douglas Gregor
operator+, directly, using the same mechanism as all other special names. Removed the "special" identifiers for the overloaded operators from the identifier table and IdentifierInfo data structure. IdentifierInfo is back to representing only real identifiers. Added a new Action, ActOnOperatorFunctionIdExpr, that builds an expression from an parsed operator-function-id (e.g., "operator +"). ActOnIdentifierExpr used to do this job, but operator-function-ids are no longer represented by IdentifierInfo's. Extended Declarator to store overloaded operator names. Sema::GetNameForDeclarator now knows how to turn the operator name into a DeclarationName for the overloaded operator. Except for (perhaps) consolidating the functionality of ActOnIdentifier, ActOnOperatorFunctionIdExpr, and ActOnConversionFunctionExpr into a common routine that builds an appropriate DeclRefExpr by looking up a DeclarationName, all of the work on normalizing declaration names should be complete with this commit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59526 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-17Introduction the DeclarationName class, as a single, general method ofDouglas Gregor
representing the names of declarations in the C family of languages. DeclarationName is used in NamedDecl to store the name of the declaration (naturally), and ObjCMethodDecl is now a NamedDecl. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59441 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-09Introduce ScopedDecl::getLexicalDeclContext() which is different from ↵Argyrios Kyrtzidis
ScopedDecl::getDeclContext() when there are nested-names. e.g.: namespace A { void f(); // SemanticDC (getDeclContext) == LexicalDC (getLexicalDeclContext) == 'namespace A' } void A::f(); // SemanticDC == namespace 'A' // LexicalDC == global namespace git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@58948 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-07Properly deserialize ParamInfo of FunctionDecl.Argyrios Kyrtzidis
When allocating an array for ParamInfo, the "decl->getNumParams()" call was used, but this will return 0 since it checks ParamInfo (which isn't yet defined and is null). The result was that ParamInfo got an array of zero length to hold the ParmVarDecls. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@58850 91177308-0d34-0410-b5e6-96231b3b80d8

2008-10-15Simplify handling of struct/union/class tags.Argyrios Kyrtzidis
Instead of using two sets of Decl kinds (Struct/Union/Class and CXXStruct/CXXUnion/CXXClass), use one 'Record' and one 'CXXRecord' Decl kind and make tag kind a property of TagDecl. Cleans up the code a bit and better reflects that Decl class structure. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@57541 91177308-0d34-0410-b5e6-96231b3b80d8

2008-10-08- Add BlockDecl AST node.Steve Naroff
- Modify BlockExpr to reference the BlockDecl. This is "cleanup" necessary to improve our lookup semantics for blocks (to fix <rdar://problem/6272905> clang block rewriter: parameter to function not imported into block?). Still some follow-up work to finish this (forthcoming). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@57298 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-05Remove "NextDecl" from RecordDecl. This change touches many files that ↵Ted Kremenek
where RecordDecl or CXXRecordDecl was constructed, always with an argument of 'NULL' for the previous declaration. The motivation behind this change is that chaining the RecordDecls is simply unnecessary. Once we create multiple RecordDecls for the same struct/union/class, clients that care about all the declarations of the same struct can build a back map by seeing which Decls refer to the same RecordType. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55821 91177308-0d34-0410-b5e6-96231b3b80d8
