Fix objc ivar lookup.  Ivar lookup should occur between lookup
of method-local values and lookup of globals.  Emulate this with
some logic in the handling of Sema::ActOnIdentifierExpr.

Two todo's left:
 1) sema shouldn't turn a bare reference to an ivar into "self->ivar"
    in the AST.  This is a hack.
 2) The new ScopedDecl::isDefinedOutsideFunctionOrMethod method does
    not correctly handle typedefs and enum constants yet.

remaining open issues I've communicated to him:

1) self can be assigned to, and his patch didn't handle it correctly.
2) CollectObjCIvarTypes is N^2 (because each subclass reprocesses
   all parent class ivars) and flattens classes.  If A derives from B, 
   and both have an int, I'd expect to get { {i32}, i32}, not { i32, i32}.

David, please review.

Added skeleton checking for NSString's method initWithFormat: (do not pass nil).  This won't be useful in most cases right now
because the analyzer isn't tracking expected types for an object, and [NSString alloc] just runs "id".

Fix a couple bozo bugs in the rewriter.

Added test case to test warning about passing 'nil' to NSString's compare: method.

Bug fix in EscapeText (for std::string) where spaces were not properly emitted.

For HTMLDiagnostics, when emitting the name of the directory, substitute the current working directory for "."

Added AnnotatedPath.h, GRAuditor.h, GRSimpleAPICheck.h and BasicObjCFoundationChecks.cpp to Xcode project.

llvm-svn: 48868

Added "GRAuditor" and "GRSimpleAPICheck" interface to allow simple stateless checkers to be injected into the analyzer.
Added "AnnotatedPath" class to record an annotated path that will be useful for inspecting paths.
Added some boilerplate code for simple checks of Apple's Foundation API.

so that all diagnostics can be piped to HTML files instead of as text diagnostics using --html-diags.

llvm-svn: 48865

PathDiagnostic no longer contains a diagnostic ID or diagnostic level.

llvm-svn: 48864

llvm-svn: 48863

llvm-svn: 48862

Added classes "PathDiagnosticPiece", "PathDiagnostic", and "PathDiagnosticClient", which encapsulate diagnostic reporting for paths.

In ObjCMessageExpr: getSelector() const should just return "Selector", not "const Selector&" because Selector is just a smart pointer.

Fix rewriter tests to work with new output file logic. This changes forces the output to standard out (rather than generate a .cpp file, which is the new default for the rewriter).

llvm-svn: 48847

Bug fix: use GetRVal instead of GetLVal (were getting the value of a DeclRefExpr, not it's address).

llvm-svn: 48846

Added test case for static analysis to warn about passing uninitialized values as arguments (not the receiver) in message expressions.

llvm-svn: 48845

Added test case for static analyzer to detect uses of uninitialized pointers as receivers in Objective-C message expressions.
Added test case directory "Analysis-Apple" which is only run on Apple (darwin) machines.

llvm-svn: 48844

Bug fix in transfer function for ObjCMessageExpr: Visit the receiver expression as an ordinary expression, not using VisitLVal.
