2013-04-08<rdar://problem/13584715> Converted constant expressions are expected to ↵Douglas Gregor
have integral values. We were assuming that any expression used as a converted constant expression would either not have a folded constant value or would be an integer, which is not the case for some ill-formed constant expressions. Because converted constant expressions are only used where integral values are expected, we can simply treat this as an error path. If that ever changes, we'll need to widen the interface of Sema::CheckConvertedConstantExpression() anyway. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@179068 91177308-0d34-0410-b5e6-96231b3b80d8

This fixes a regression I introduced in r178136, where we would not consider the using directives from the semantic declaration contexts that aren't represented by the lexical scopes (Scope) when performing unqualified name lookup. This lead to horribly funny diagnostics like "no identifier named 'foo'; did you mean 'foo'?". git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@179067 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-08<rdar://problem/12806802> Propagate access specifiers for conversion ↵Douglas Gregor
functions to the conversion function set eagerly. This slightly propagates an existing hack that delays when we provide access specifiers for the visible conversion functions of a class by copying the available access specifier early. The only client this affects is LLDB, which tends to discover and add conversion functions after the class is technically "complete". As such, the only observable difference is in LLDB, so the testing will go there. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@179029 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-06[analyzer] When creating a trimmed graph, preserve whether a node is a sink.Jordan Rose
This is important because sometimes two nodes are identical, except the second one is a sink. This bug has probably been around for a while, but it wouldn't have been an issue in the old report graph algorithm. I'm ashamed to say I actually looked at this the first time around and thought it would never be a problem...and then didn't include an assertion to back that up.

2013-04-06Rework how ObjC method inherit deprecated/availability.Ted Kremenek
New rule: - Method decls in @implementation are considered "redeclarations" and inherit deprecated/availability from the @interface. - All other cases are consider overrides, which do not inherit deprecated/availability. For example: (a) @interface redeclares a method in an adopted protocol. (b) A subclass redeclares a method in a superclass. (c) A protocol redeclares a method from another protocol it adopts. The idea is that API authors should have the ability to easily move availability/deprecated up and down a class/protocol hierarchy. A redeclaration means that the availability/deprecation is a blank slate.
