2008-04-16Take first step to migrating handling of "stores" to values from GRExprEngineTed Kremenek
to the plug-in GRTransferFuncs object. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49801 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-15Added some comments to GRExprEngine. Reorder some of the method definitionsTed Kremenek
to start logically organizing them. Added initial plug-in transfer function support for Objective-C message expressions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49752 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-15Remove FileVarDecl and BlockVarDecl. They are replaced by ↵Steve Naroff
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). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49748 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-10Fixed some logic errors in the CF ref count checker; we now can detect simpleTed Kremenek
use-after-release errors. Added test case. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49509 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-09Major refactoring/cleanup of GRExprEngine, ExplodedGraph, and BugReporter.Ted Kremenek
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49453 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-02simplify some code by using PointerLikeType.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49101 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-31Added path-sensitive check for return statements that return the addressTed Kremenek
of a stack variable. This is the path-sensitive version of a check that is already done during semantic analysis. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48980 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-27Hooked up initial NSString interface checking to GRSimpleVals.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48895 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-27Added "GRAuditor" and "GRSimpleAPICheck" interface to allow simple stateless ↵Ted Kremenek
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48867 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-26Bug fix: use GetRVal instead of GetLVal (were getting the value of a ↵Ted Kremenek
DeclRefExpr, not it's address). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48846 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-26Bug fix in transfer function for ObjCMessageExpr: Visit the receiver ↵Ted Kremenek
expression as an ordinary expression, not using VisitLVal. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48842 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-25Tweak to transfer function for ObjCMessageExpr: handle both instance methodsTed Kremenek
and message expressions with a specified receiver. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48773 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-25Added logic to check for uninitialized values as the receivers for message ↵Ted Kremenek
expressions and uninitialized values passed-by-value as arguments to message expressions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48760 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-25Added initial transfer function support for ObjCMessageExpr.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48757 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-21Rename "Nodify" to "MakeNode"Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48659 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-17Fix assertion.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48470 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-17Fix integer overflow bug when processing switch statements.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48469 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-17Properly hook up inline asm transfer function logic to the main GRExprEngine ↵Ted Kremenek
logic. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48468 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-17Added initial transfer function support for inline asm.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48466 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-15Make a major restructuring of the clang tree: introduce a top-levelChris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48402 91177308-0d34-0410-b5e6-96231b3b80d8
