2013-04-03Don't compute a patched/semantic storage class.Rafael Espindola
For variables and functions clang used to store two storage classes. The one "as written" in the code and a patched one, which, for example, propagates static to the following decls. This apparently is from the days clang lacked linkage computation. It is now redundant and this patch removes it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@178663 91177308-0d34-0410-b5e6-96231b3b80d8

Introduce a new AST Decl node "EmptyDecl" to model empty-declaration.

2013-02-18Ensure that the identifier chains have the most recent declaration after ↵Douglas Gregor
module deserialization. This commit introduces a set of related changes to ensure that the declaration that shows up in the identifier chain after deserializing declarations with a given identifier is, in fact, the most recent declaration. The primary change involves waiting until after we deserialize and wire up redeclaration chains before updating the identifier chains. There is a minor optimization in here to avoid recursively deserializing names as part of looking to see whether top-level declarations for a given name exist. A related change that became suddenly more urgent is to property record a merged declaration when an entity first declared in the current translation unit is later deserialized from a module (that had not been loaded at the time of the original declaration). Since we key off the canonical declaration (which is parsed, not from an AST file) for emitted redeclarations, we simply record this as a merged declaration during AST writing and let the readers merge them. Re-fixes <rdar://problem/13189985>, presumably for good this time. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175447 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-07Fix handling of module imports adding names to a DeclContext after qualifiedRichard Smith
name lookup has been performed in that context (this probably only happens in C++). 1) Whenever we add names to a context, set a flag on it, and if we perform lookup and discover that the context has had a lookup table built but has the flag set, update all entries in the lookup table with additional names from the external source. 2) When marking a DeclContext as having external visible decls, mark the context in which lookup is performed, not the one we are adding. These won't be the same if we're adding another copy of a pre-existing namespace. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174577 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-16Rework the traversal of Objective-C categories and extensions toDouglas Gregor
consider (sub)module visibility. The bulk of this change replaces myriad hand-rolled loops over the linked list of Objective-C categories/extensions attached to an interface declaration with loops using one of the four new category iterator kinds: visible_categories_iterator: Iterates over all visible categories and extensions, hiding any that have their "hidden" bit set. This is by far the most commonly used iterator. known_categories_iterator: Iterates over all categories and extensions, ignoring the "hidden" bit. This tends to be used for redeclaration-like traversals. visible_extensions_iterator: Iterates over all visible extensions, hiding any that have their "hidden" bit set. known_extensions_iterator: Iterates over all extensions, whether they are visible to normal name lookup or not. The effect of this change is that any uses of the visible_ iterators will respect module-import visibility. See the new tests for examples. Note that the old accessors for categories and extensions are gone; there are *Raw() forms for some of them, for those (few) areas of the compiler that have to manipulate the linked list of categories directly. This is generally discouraged. Part two of <rdar://problem/10634711>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172665 91177308-0d34-0410-b5e6-96231b3b80d8

per review discussion in r170365 This does limit these typedefs to being sequences, but no current usage requires them to be contiguous (we could expand this to a more general iterator pair range concept at some point). Also, it'd be nice if SmallVector were constructible directly from an ArrayRef but this is a bit tricky since ArrayRef depends on SmallVectorBaseImpl for the inverse conversion.

2012-12-08Finish implementing 'selected constructor' rules for triviality in C++11. InRichard Smith
the cases where we can't determine whether special members would be trivial while building the class, we eagerly declare those special members. The impact of this is bounded, since it does not trigger implicit declarations of special members in classes which merely *use* those classes. In order to determine whether we need to apply this rule, we also need to eagerly declare move operations and destructors in cases where they might be deleted. If a move operation were supposed to be deleted, it would instead be suppressed, and we could need overload resolution to determine if we fall back to a trivial copy operation. If a destructor were implicitly deleted, it would cause the move constructor of any derived classes to be suppressed. As discussed on cxx-abi-dev, C++11's selected constructor rules are also retroactively applied as a defect resolution in C++03 mode, in order to identify that class B has a non-trivial copy constructor (since it calls A's constructor template, not A's copy constructor): struct A { template<typename T> A(T &); }; struct B { mutable A a; }; git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169673 91177308-0d34-0410-b5e6-96231b3b80d8

2012-11-06[PCH] Write out the ClassTemplateDecl::Common::InjectedClassNameType typeArgyrios Kyrtzidis
reference instead of relying on computing it. In general, if storage is no issue, it is preferable to deserialize info from the PCH instead of trying to recompute it after the PCH was loaded. The incentive to change this now was due to r155303 changing how friend template classes in dependent contexts are handled; such classes can now be chained to a previous template class but the computed InjectedClassNameType may be different due to the extra template parameters from the dependent context. The new handling requires more investigation but, in the meantime, writing out InjectedClassNameType fixes PCH issue in rdar://12627738. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@167425 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-10Rename ObjCMethodDecl::isSynthesized to isPropertyAccessor.Jordan Rose
This more accurately reflects its use: this flag is set when a method matches the getter or setter name for a property in the same class, and does not actually specify whether or not the definition of the method will be synthesized (either implicitly or explicitly with @synthesize). This renames the setter and backing field as well, and changes the (soon-to-be-obsolete?) XML dump format to use 'property_accessor' instead of 'synthesized'. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@165626 91177308-0d34-0410-b5e6-96231b3b80d8
