Ted Kremenek 90c7cb6810 Hook up "EvalStore" from GRTransferFuncs to GRExprEngine. 
llvm-svn: 49804
 2008-04-16 18:39:06 +00:00
Ted Kremenek 2044a5183d Take first step to migrating handling of "stores" to values from GRExprEngine 
to the plug-in GRTransferFuncs object.

Ted Kremenek 667cacb2ff Added some comments to GRExprEngine. Reorder some of the method definitions 
to start logically organizing them.

Added initial plug-in transfer function support for Objective-C message expressions.

Steve Naroff 08899ff85d Remove FileVarDecl and BlockVarDecl. They are replaced by VarDecl::isBlockVarDecl() and VarDecl::isFileVarDecl(). 
This is a fairly mechanical/large change. As a result, I avoided making any changes/simplifications that weren't directly related. I did break two Analysis tests. I also have a couple FIXME's in UninitializedValues.cpp. Ted, can you take a look? If the bug isn't obvious, I am happy to dig in and fix it (since I broke it).

Ted Kremenek 4b77209694 Fixed some logic errors in the CF ref count checker; we now can detect simple 
use-after-release errors.  Added test case.

Ted Kremenek 7acc3a36ef Major refactoring/cleanup of GRExprEngine, ExplodedGraph, and BugReporter. 
Bugs are now reported using a combination of "BugType" (previously
BugDescription) and Bug "BugReport" objects, which are fed to BugReporter (which
generates PathDiagnostics). This provides a far more modular way of registering
bug types and plugging in diagnostics.

GRExprEngine now owns its copy of GRCoreEngine, and is not owned by the
ExplodedGraph.

ExplodedGraph is no longer templated on the "checker", but instead on the state
contained in the nodes.

Chris Lattner 182f660d8d simplify some code by using PointerLikeType.

Ted Kremenek f646774f32 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.

Ted Kremenek 27156c8c9f Hooked up initial NSString interface checking to GRSimpleVals.

 2008-03-27 21:15:17 +00:00
Ted Kremenek c04149299c 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.

Ted Kremenek ea128437b3 Bug fix: use GetRVal instead of GetLVal (were getting the value of a DeclRefExpr, not it's address).

Ted Kremenek cb047289a8 Bug fix in transfer function for ObjCMessageExpr: Visit the receiver expression as an ordinary expression, not using VisitLVal. 
llvm-svn: 48842
 2008-03-26 21:36:08 +00:00
Ted Kremenek 3335120f69 Tweak to transfer function for ObjCMessageExpr: handle both instance methods 
and message expressions with a specified receiver.

 2008-03-25 16:07:41 +00:00
Ted Kremenek 945a246ad8 Added logic to check for uninitialized values as the receivers for message expressions 
and uninitialized values passed-by-value as arguments to message expressions.

Ted Kremenek 58021a617b Properly hook up inline asm transfer function logic to the main GRExprEngine logic.

Chris Lattner 7a51313d8a 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.
