2011-05-06When checking for a prior declaration of the name of a namespace, skipDouglas Gregor
any names that aren't in the appropriate identifier namespaces. Fixes an embarrassing bug where we give a redefinition error due to an Objective-C category (<rdar://problem/9388207>). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@131036 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@131018 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-06Modify some deleted function methods to better reflect reality:Sean Hunt
- New isDefined() function checks for deletedness - isThisDeclarationADefinition checks for deletedness - New doesThisDeclarationHaveABody() does what isThisDeclarationADefinition() used to do - The IsDeleted bit is not propagated across redeclarations - isDeleted() now checks the canoncial declaration - New isDeletedAsWritten() does what it says on the tin. - isUserProvided() now correct (thanks Richard!) This fixes the bug that we weren't catching void foo() = delete; void foo() {} as being a redefinition. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@131013 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-06Do defaulted constructors properly.Sean Hunt
Explictly defaultedness is correctly reflected on the AST, but there are no changes to how that affects the definition of functions or much else really. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@130974 91177308-0d34-0410-b5e6-96231b3b80d8

2011-05-04there i fixed itSean Hunt
Increase robustness of the delegating constructor cycle detection mechanism. No more infinite loops on invalid or logic errors leading to false results. Ensure that this is maintained correctly accross serialization. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@130887 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-04Implement a better version of delegating constructor cycle detection.Sean Hunt
This is more efficient as it's all done at once at the end of the TU. This could still get expensive, so a flag is provided to disable it. As an added bonus, the diagnostics will now print out a cycle. The PCH test is XFAILed because we currently can't deal with a note emitted in the header and I, being tired, see no other way to verify the serialization of delegating constructors. We should probably address this problem /somehow/ but no good solution comes to mind. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@130836 91177308-0d34-0410-b5e6-96231b3b80d8

2011-05-03Ensure that destructors are properly inovked when an exception leavesSean Hunt
the body of a delegating constructor call. This means that the delegating constructor implementation should be complete and correct, though there are some rough edges (diagnostic quality with the cycle detection and using a deleted destructor). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@130803 91177308-0d34-0410-b5e6-96231b3b80d8

2011-05-01Fully implement delegating constructors!Sean Hunt
As far as I know, this implementation is complete but might be missing a few optimizations. Exceptions and virtual bases are handled correctly. Because I'm an optimist, the web page has appropriately been updated. If I'm wrong, feel free to downgrade its support categories. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@130642 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-24Synthesizing the definition of an implicit member is an AST modification, so ↵Sebastian Redl
notify any mutation listeners of it. This fixes a crasher in chained PCH, where an implicit destructor in a PCH gets a definition in a chained PCH, which is then lost. However, any further use of the destructor would cause its definition to be regenerated in the final file, hiding the bug. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@130103 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-22At the end of the translation unit, defining a vtable can introduceDouglas Gregor
new templates that need to be instantiated and vice-versa. Iterate until we've instantiated all required templates and defined all required vtables. Fixed PR9325 / <rdar://problem/9055177>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@130023 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-22Add -fdelayed-template-parsing option. Using this option all templated ↵Francois Pichet
function definitions are parsed at the end of the translation unit only if it is required by an actual instantiation. As such all the symbols of the TU are available during name lookup. Using this flag is necessary for compatibility with Microsoft template code. This also provides some parsing speed improvement. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@130022 91177308-0d34-0410-b5e6-96231b3b80d8

2011-04-08Use ExprResult& instead of Expr *& in SemaJohn Wiegley
This patch authored by Eric Niebler. Many methods on the Sema class (e.g. ConvertPropertyForRValue) take Expr pointers as in/out parameters (Expr *&). This is especially true for the routines that apply implicit conversions to nodes in-place. This design is workable only as long as those conversions cannot fail. If they are allowed to fail, they need a way to report their failures. The typical way of doing this in clang is to use an ExprResult, which has an extra bit to signal a valid/invalid state. Returning ExprResult is de riguour elsewhere in the Sema interface. We suggest changing the Expr *& parameters in the Sema interface to ExprResult &. This increases interface consistency and maintainability. This interface change is important for work supporting MS-style C++ properties. For reasons explained here <http://lists.cs.uiuc.edu/pipermail/cfe-dev/2011-February/013180.html>, seemingly trivial operations like rvalue/lvalue conversions that formerly could not fail now can. (The reason is that given the semantics of the feature, getter/setter method lookup cannot happen until the point of use, at which point it may be found that the method does not exist, or it may have the wrong type, or overload resolution may fail, or it may be inaccessible.) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@129143 91177308-0d34-0410-b5e6-96231b3b80d8
