2013-02-20Add a new 'type_visibility' attribute to allow users toJohn McCall
control the visibility of a type for the purposes of RTTI and template argument restrictions independently of how visibility propagates to its non-type member declarations. Also fix r175326 to not ignore template argument visibility on a template explicit instantiation when a member has an explicit attribute but the instantiation does not.

2013-02-19Add support for -fvisibility-ms-compat.John McCall
We treat this as an alternative to -fvisibility=<?> which changes the default value visibility to "hidden" and the default type visibility to "default". Expose a -cc1 option for changing the default type visibility, repurposing -fvisibility as the default value visibility option (also setting type visibility from it in the absence of a specific option). rdar://13079314 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175480 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-18Replace TypeLoc llvm::cast support to be well-defined.David Blaikie
The TypeLoc hierarchy used the llvm::cast machinery to perform undefined behavior by casting pointers/references to TypeLoc objects to derived types and then using the derived copy constructors (or even returning pointers to derived types that actually point to the original TypeLoc object). Some context is in this thread: http://lists.cs.uiuc.edu/pipermail/llvmdev/2012-December/056804.html Though it's spread over a few months which can be hard to read in the mail archive. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175462 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-16Rework the visibility computation algorithm in preparationJohn McCall
for distinguishing type vs. value visibility. The changes to the visibility of explicit specializations are intentional. The change to the "ugly" test case is a consequence of a sensible implementation, and I am happy to argue that this is better behavior. Other changes may or may not be intended; it is quite difficult to divine intent from some of the code I altered. I've left behind a comment which I hope explains the philosophy behind visibility computation. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175326 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-14merge hasCLanguageLinkage and isExternC. Keep the shorter name.Rafael Espindola
I added hasCLanguageLinkage while fixing some language linkage bugs some time ago so that I wouldn't have to check all users of isExternC. It turned out to be a much longer detour than expected, but this patch finally merges the two again. The isExternC function now implements just the standard notion of having C language linkage. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175119 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-14Add a getLanguageLinkage method to VarDecls and FunctionDecls. Use it to fixRafael Espindola
some cases where functions with no language linkage were being treated as having C language linkage. In particular, don't warn in extern "C" { static NonPod foo(); } Since getLanguageLinkage checks the language linkage, the linkage computation cannot use the language linkage. Break the loop by checking just the context in the linkage computation. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175117 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-09Ensure that type definitions present in just-loaded modules areDouglas Gregor
visible. The basic problem here is that a given translation unit can use forward declarations to form pointers to a given type, say, class X; X *x; and then import a module that includes a definition of X: import XDef; We will then fail when attempting to access a member of X, e.g., x->method() because the AST reader did not know to look for a default of a class named X within the new module. This implementation is a bit of a C-centric hack, because the only definitions that can have this property are enums, structs, unions, Objective-C classes, and Objective-C protocols, and all of those are either visible at the top-level or can't be defined later. Hence, we can use the out-of-date-ness of the name and the identifier-update mechanism to force the update. In C++, we will not be so lucky, and will need a more advanced solution, because the definitions could be in namespaces defined in two different modules, e.g., // module 1 namespace N { struct X; } // module 2 namespace N { struct X { /* ... */ }; } One possible implementation here is for C++ to extend the information associated with each identifier table to include the declaration IDs of any definitions associated with that name, regardless of context. We would have to eagerly load those definitions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174794 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-08Fix stack overflow and improve performance when a module contains manyRichard Smith
overloads of a name by claiming that there are no lookup results for that name in modules while loading the names from the module. Lookups in deserialization really don't want to find names which they themselves are in the process of introducing. This also has the pleasant side-effect of automatically caching PCH lookups which found no names. The runtime here is still quadratic in the number of overloads, but the constant is lower. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174685 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
2013-02-07Simplify FindExternalVisibleDeclsByName by making it return a bool indicatingRichard Smith
if it found any decls, rather than returning a list of found decls. This removes a returning-ArrayRef-to-deleted-storage bug from MultiplexExternalSemaSource (in code not exercised by any of the clang binaries), reduces the work required in the found-no-decls case with PCH, and importantly removes the need for DeclContext::lookup to be reentrant.
