2013-02-14objective-C: When implementing custom accessor method forFariborz Jahanian
a property, the -Wdirect-ivar-access should not warn when accessing the property's synthesized instance variable. // rdar://13142820 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175195 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-02This patch makes "&Cls::purevfn" not an odr use. This isn't what the standardNick Lewycky
says, but that's a defect (to be filed). "Cls::purevfn()" is still an odr use. Also fixes a bug that caused us to not mark the function referenced just because we didn't want to mark it odr used. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174242 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-01[Sema][Attr]Fix alignment attribute printing.Michael Han
Remove "IsMSDeclspec" argument from Align attribute since the arguments in Attr.td should only model those appear in source code. Introduce attribute Accessor, and teach TableGen to generate syntax kind accessors for Align attribute, and use those accessors to decide if an alignment attribute is a declspec attribute. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174133 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-24PR14922: when printing an attribute, use the real syntax of the attribute ↵Michael Han
(GNU, C++11, MS Declspec) instead of hardcoded GNU syntax. Introduce a spelling index to Attr class, which is an index into the attribute spelling list of an attribute defined in Attr.td. This index will determine the actual spelling used by an attribute, as it incorporates both the syntax and naming of the attribute. When constructing an attribute AST node, the spelling index is computed based on attribute kind, scope (if it's a C++11 attribute), and name, then passed to Attr that will use the index to print itself. Thanks to Richard Smith for the idea and review. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173358 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-21Eliminate Sema::CompareProperties(), which was walking over a pile ofDouglas Gregor
lexical declarations looking for properties when we could more efficiently check for property mismatches at property declaration time.

copy-list-initialization (and doesn't add an additional copy step): Fill in the ListInitialization bit when creating a CXXConstructExpr. Use it when instantiating initializers in order to correctly handle instantiation of copy-list-initialization.

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

2012-11-29The declaration of a special member can require overload resolution to beRichard Smith
