Added path-sensitive check for return statements that return the address
...
of a stack variable. This is the path-sensitive version of a check that
is already done during semantic analysis.

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".

Expanded NSString checking to check for nil for a few more methods.

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.

PathDiagnosticPiece no longer contains a vector of strings; just one string.

PathDiagnostic no longer contains a diagnostic ID or diagnostic level.

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

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

GRSimple analysis now outputs additional diagnostic warnings about

passing an uninitialized value to a message expresion.

Tweak to transfer function for ObjCMessageExpr: handle both instance methods
...
and message expressions with a specified receiver.
llvm-svn: 48773

Added logic to check for uninitialized values as the receivers for message expressions
...
and uninitialized values passed-by-value as arguments to message expressions.

Changed merge operation for uninitialized values analysis to "intersect" (previous union).
...
The effect is that if a variable is uninitialized along a branch (but initialized along another), at merge points it is considered uninitialized. Previously we had the opposite behavior. The new behavior is more conservative, and more in line with gcc's behavior.

LiveVariables analysis now uses intersect for the merge of block-level expression liveness information.
...
The rationale is that a block-level expression cannot be live in a parent block unless it is live in all of the successor blocks.

Make a major restructuring of the clang tree: introduce a top-level
...
lib dir and move all the libraries into it. This follows the main
llvm tree, and allows the libraries to be built in parallel. The
top level now enforces that all the libs are built before Driver,
but we don't care what order the libs are built in. This speeds
up parallel builds, particularly incremental ones.
