2011-11-01Fix the representation of wide strings in the AST and IR so that it uses the ↵Eli Friedman
native representation of integers for the elements. This fixes a bunch of nastiness involving treating wide strings as a series of bytes. Patch by Seth Cantrell. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@143417 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-26Fix pr9614 by not emitting an available_externally function when it callsRafael Espindola

2011-10-25Introduce a placeholder type for "pseudo object"John McCall
expressions: expressions which refer to a logical rather than a physical l-value, where the logical object is actually accessed via custom getter/setter code. A subsequent patch will generalize the AST for these so that arbitrary "implementing" sub-expressions can be provided. Right now the only client is ObjC properties, but this should be generalizable to similar language features, e.g. Managed C++'s __property methods. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142914 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-25Implement support for dependent Microsoft __if_exists/__if_not_existsDouglas Gregor
statements. As noted in the documentation for the AST node, the semantics of __if_exists/__if_not_exists are somewhat different from the way Visual C++ implements them, because our parsed-template representation can't accommodate VC++ semantics without serious contortions. Hopefully this implementation is "good enough". git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142901 91177308-0d34-0410-b5e6-96231b3b80d8
