2013-04-09[analyzer] Replace isIntegerType() with isIntegerOrEnumerationType().Jordan Rose
Previously, the analyzer used isIntegerType() everywhere, which uses the C definition of "integer". The C++ predicate with the same behavior is isIntegerOrUnscopedEnumerationType(). However, the analyzer is /really/ using this to ask if it's some sort of "integrally representable" type, i.e. it should include C++11 scoped enumerations as well. hasIntegerRepresentation() sounds like the right predicate, but that includes vectors, which the analyzer represents by its elements. This commit audits all uses of isIntegerType() and replaces them with the general isIntegerOrEnumerationType(), except in some specific cases where it makes sense to exclude scoped enumerations, or any enumerations. These cases now use isIntegerOrUnscopedEnumerationType() and getAs<BuiltinType>() plus BuiltinType::isInteger(). isIntegerType() is hereby banned in the analyzer - lib/StaticAnalysis and include/clang/StaticAnalysis. :-) Fixes real assertion failures.

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 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.
