2009-01-10Allow multiple Microsoft calling-convention keywords. Fixes ↵Douglas Gregor
rdar://problem/6486133 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62018 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-09When we see a reference to a struct, class, or union like "struct X"Douglas Gregor
that is neither a definition nor a forward declaration and where X has not yet been declared as a tag, introduce a declaration into the appropriate scope (which is likely *not* to be the current scope). The rules for the placement of the declaration differ slightly in C and C++, so we implement both and test the various corner cases. This implementation isn't 100% correct due to some lingering issues with the function prototype scope (for a function parameter list) not being the same scope as the scope of the function definition. Testcase is FIXME'd; this probably isn't an important issue. Addresses <rdar://problem/6484805>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62014 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-08Unify the code for defining tags in C and C++, so that we alwaysDouglas Gregor
introduce a Scope for the body of a tag. This reduces the number of semantic differences between C and C++ structs and unions, and will help with other features (e.g., anonymous unions) in C. Some important points: - Fields are now in the "member" namespace (IDNS_Member), to keep them separate from tags and ordinary names in C. See the new test in Sema/member-reference.c for an example of why this matters. In C++, ordinary and member name lookup will find members in both the ordinary and member namespace, so the difference between IDNS_Member and IDNS_Ordinary is erased by Sema::LookupDecl (but only in C++!). - We always introduce a Scope and push a DeclContext when we're defining a tag, in both C and C++. Previously, we had different actions and different Scope/CurContext behavior for enums, C structs/unions, and C++ structs/unions/classes. Now, it's one pair of actions. (Yay!) There's still some fuzziness in the handling of struct/union/enum definitions within other struct/union/enum definitions in C. We'll need to do some more cleanup to eliminate some reliance on CurContext before we can solve this issue for real. What we want is for something like this: struct X { struct T { int x; } t; }; to introduce T into translation unit scope (placing it at the appropriate point in the IdentifierResolver chain, too), but it should still have struct X as its lexical declaration context. PushOnScopeChains isn't smart enough to do that yet, though, so there's a FIXME test in nested-redef.c git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@61940 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

2008-12-24Correct the order in which we cope with end-of-class-definitionDouglas Gregor
semantics and improve our handling of default arguments. Specifically, we follow this order: - As soon as the see the '}' in the class definition, the class is complete and we add any implicit declarations (default constructor, copy constructor, etc.) to the class. - If there are any default function arguments, parse them - If there were any inline member function definitions, parse them As part of this change, we now keep track of the the fact that we've seen unparsed default function arguments within the AST. See the new ParmVarDecl::hasUnparsedDefaultArg member. This allows us to properly cope with calls inside default function arguments to other functions where we're making use of the default arguments. Made some C++ error messages regarding failed initializations more specific. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@61406 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

2008-11-23Convert IdentifierInfo's to be printed the same as DeclarationNames Chris Lattner
with implicit quotes around them. This has a bunch of follow-on effects and requires tweaking to a whole lot of code. This causes a regression in two tests (xfailed) by causing it to emit things like: Line 10: duplicate interface declaration for category 'MyClass1' ('Category1') instead of: Line 10: duplicate interface declaration for category 'MyClass1(Category1)' I will fix this in a follow-up commit. As part of this, I had to start switching stuff to use ->getDeclName() instead of Decl::getName() for consistency. This is good, but I was planning to do this as an independent patch. There will be several follow-on patches to clean up some of the mess, but this patch is already too big. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59917 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

2008-11-12Don't build identifiers for C++ constructors, destructors, orDouglas Gregor
conversion functions. Instead, we just use a placeholder identifier for these (e.g., "<constructor>") and override NamedDecl::getName() to provide a human-readable name. This is one potential solution to the problem; another solution would be to replace the use of IdentifierInfo* in NamedDecl with a different class that deals with identifiers better.
