2012-12-28Reject overloading of two static extern C functions.Rafael Espindola
This patch moves hasCLanguageLinkage to be VarDecl and FunctionDecl methods so that they can be used from SemaOverload.cpp and then fixes the logic in Sema::IsOverload. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171193 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-25Add 171048 back but invalidate the cache of all redeclarations when settingRafael Espindola
the body of a functions. The problem was that hasBody looks at the entire chain and causes problems to -fvisibility-inlines-hidden if the cache was not invalidated. Original message: Cache visibility of decls. This unifies the linkage and visibility caching. I first implemented this when working on pr13844, but the previous fixes removed the performance advantage of this one. This is still a step in the right direction for making linkage and visibility cheap to use. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171053 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-18Merge storage classes even when contexts don't match.Rafael Espindola
This fixes the storage class of extern decls that are merged with file level statics. The patch also fixes the linkage computation so that they are considered internal. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@170406 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-17Fix isThisDeclarationADefinition for extern following tentative.Rafael Espindola
An extern declaration following a tentative definition should not itself be considered a tentative definition. Fixes pr14614. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@170377 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-08Properly compute triviality for explicitly-defaulted or deleted special members.Richard Smith
Remove pre-standard restriction on explicitly-defaulted copy constructors with 'incorrect' parameter types, and instead just make those special members non-trivial as the standard requires. This required making CXXRecordDecl correctly handle classes which have both a trivial and a non-trivial special member of the same kind. This also fixes PR13217 by reimplementing DiagnoseNontrivial in terms of the new triviality computation technology. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169667 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-04Sort all of Clang's files under 'lib', and fix up the broken headersChandler Carruth
uncovered. This required manually correcting all of the incorrect main-module headers I could find, and running the new llvm/utils/sort_includes.py script over the files. I also manually added quite a few missing headers that were uncovered by shuffling the order or moving headers up to be main-module-headers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169237 91177308-0d34-0410-b5e6-96231b3b80d8

2012-11-14Provide the correct mangling and linkage for certain unnamed nested classes.David Blaikie
This corrects the mangling and linkage of classes (& their member functions) in cases like this: struct foo { struct { void func() { ... } } x; }; we were accidentally giving this nested unnamed struct 'no' linkage where it should've had the linkage of the outer class. The mangling was incorrecty too, mangling as TU-wide unnamed type mangling of $_X rather than class-scoped mangling of UtX_. This also fixes -Wunused-member-function which would incorrectly diagnose 'func' as unused due to it having no linkage & thus appearing to be TU-local when in fact it might be correctly used in another TU. Similar mangling should be applied to function local classes in similar cases but I've deferred that for a subsequent patch.

of the initializer is valid before using it. Fixes rdar://12455002&12449015 where local variables of objc objects in ARC mode were not annotated because of the ImplicitValueInitExpr initializer having invalid source range, resulting in the SourceRange of the VarDecl having invalid end location. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@165456 91177308-0d34-0410-b5e6-96231b3b80d8
2012-09-26Fix the AST representation for non-type template arguments to encodeEli Friedman

2012-06-08PR13051: If a constructor is explicitly defaulted, it isn't marked as beingRichard Smith
constexpr until we get to the end of the class definition. When that happens, be sure to remember that the class actually does have a constexpr constructor. This is a stopgap solution, which still doesn't cover the case of a class with multiple copy constructors (only some of which are constexpr). We should be performing constructor lookup when implicitly defining a constructor in order to determine whether all constructors it invokes are constexpr. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158228 91177308-0d34-0410-b5e6-96231b3b80d8
