Ted Kremenek 91614e6fe6 Renamed deterministic EvalBinOp to DetermEvalBinOpNN. This name mangling is unfortunately needed because virtual methods with the same name can be hidden by subclasses.

2008-07-18 15:27:58 +00:00
Ted Kremenek 8d6b42e096 Created ValueStateSet class to manage the creation of multiple states by a method.
Modified the new EvalBinOpNN to generate states instead of nodes.  This is a much simpler interface and is what clients will want to do.

Argyrios Kyrtzidis ef34aed1f9 Unify ctx_iterator/ctx_begin()/ctx_end() and iterator/begin()/end() so that a single iterator type is used for both traversing decls of the same declaration context *and* of the parent declaration contexts, depending on the value of the bool parameter 'LookInParentCtx' that is passed to IdentifierResolver::begin().

2008-07-16 19:47:39 +00:00
Steve Naroff 8dd1525b9a RewriteObjC::Initialize(): add function decls used by @synchronized.
This fixes <rdar://problem/6040143> clang ObjC rewriter: @synchronized keyword inserts undeclared objc functions.

llvm-svn: 53695
2008-07-16 18:58:11 +00:00
Steve Naroff de7d0f69ba Two fixes:
- Make sure ObjCIvarDecl propagates the bitfield width.
- RewriteObjC::SynthesizeIvarOffsetComputation(): Avoid using the __OFFSETOF__ mumbo jumbo for bitfields (since it isn't legal C). This fixes <rdar://problem/5986079> clang ObjC rewriter: bitfields and ivar access don't mix.

Argyrios Kyrtzidis 7da34d050b When checking for name collision between a tag and a previously defined namespace, the collision occured even when the tag was in a different nested scope.
Fix it by taking into account the scope when checking for namespace-tag name collisions.

Ted Kremenek ae543148bc Fix regression introduced by http://lists.cs.uiuc.edu/pipermail/cfe-commits/Week-of-Mon-20080714/006514.html.
The regression was the casts from integers to pointers where not being handled: they would just return UnknownVal.  This would greatly decrease path-sensitivity.

llvm-svn: 53645
2008-07-15 22:38:34 +00:00
Ted Kremenek 8e3704d35a Added parsing/sema support for __attribute__ ((IBOutlet)), a clang-specific attribute that the static analyzer will use to recognize what ivars are IBOutlets.
llvm-svn: 53644
2008-07-15 22:26:48 +00:00
Ted Kremenek 3879c5f6e4 Added --status-bugs option to scan-build. By default, the exit status of
scan-build is the same as the exit status of the executed build command. With
this option, the exit status of scan-build is 1 if the analyzer flagged any
bugs, and 0 otherwise.

This addresses: <rdar://problem/6075320>

Nate Begeman 191a6b1f1b http://llvm.org/bugs/show_bug.cgi?id=2523
Add some code to handle vector comparisons, which is the language side

Ted Kremenek 3bfb314c25 Add new check: -check-objc-methodsigs. This check scans methods in
ObjCImplementationDecls and sees if a ancestor class defines a method with the
same selector but with a different type signature. Right now it just compares
return types, and mainly looks at differences in primitive values. The checking
will be expanded in the future.
