2008-04-10Refactored all logic to run the GRSimpleVals and CFRef checker into a commonTed Kremenek
code path in the clang driver. Renamed options --grsimple to -checker-simple and -check-cfref to -checker-cfref. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49500 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-10CFRefCount analysis now properly calls "EmitWarnings" after analyzing a ↵Ted Kremenek
function. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49488 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-10When not emitting path diagnostics in BugReporter::EmitWarning(), use theTed Kremenek
BugReport-specific SourceRanges (when available). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49486 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-10Fixed regressions in error reporting due to copy-paste errors (using the "begin"Ted Kremenek
iterator instead of "end") and not implementing "getDescription()" for Nil argument checks. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49485 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-09Hooked up initial reference-count checks to the BugReporter interface.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49455 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
2008-04-09Added some boilerplate for emitting warnings from the CF-reference count ↵Ted Kremenek
checker. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49414 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-09Added new "BugReporterHelper" class which is used by BugReporter to emitTed Kremenek
checker-specific diagnostics. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49412 91177308-0d34-0410-b5e6-96231b3b80d8

2008-04-03Added investigate patch for an occasionally failing assertion (heisenbug?)Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49193 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-03Better range highlight for undefined-argument checks.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49184 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-03When reporting "bad receiver" warnings, highlight the receiver.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49183 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-03Use "getRanges" in default implementation of "getEndPath" to determineTed Kremenek
the ranges of highlighted elements in the source code. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49181 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-03Hooked up GRSimpleAPICheck and the simple Objective-C Foundation checks to useTed Kremenek
the new BugReporter interface. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49180 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49155 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-03Add back bug name to PathDiagnostic.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49139 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-03When creating PathDiagnostics, created a trimmed graph first and report theTed Kremenek
BFS path to the root. This also avoids problems with loops in the ExplodedGraph. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49133 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-03Created new path-sensitive bug-reporting scheme based on the classesTed Kremenek
"BugReporter" and "BugDescription". BugDescription is used to describe a bug and provide pieces of the PathDiagnostic, and BugReporter creates the actual PathDiagnostic by crawling through the ExplodedGraph. Migrated checks done by GRSimpleVals to be reported using the new BugReporter mechanism. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49127 91177308-0d34-0410-b5e6-96231b3b80d8

2008-04-02Added more PathDiagnostic rendering for terminators: switch, goto, loops.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49119 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
2008-04-02Beginning of some cleanups; start generating path diagnostics using objectsTed Kremenek
that describe a bug. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49086 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-02Added initial hacked support for display path diagnostics withTed Kremenek
GRSimpleVals warnings. Cleaning up, but now we get multiple bubbles (branches are annotated). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49077 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-01Patch by Argiris Kirtzidis: Fix a dangling pointer error!Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49057 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-31Do not prepend the keyword "[CHECKER]" to checker messages when usingTed Kremenek
a PathDiagnosticClient. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48996 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-31Include ranges in GRSimpleVals diagnostics.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48990 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-31Inlined clang/Analysis/Analyses/GRSimpleVals.h into LocalCheckers.h and removedTed Kremenek
GRSimpleVals.h Added a PathDiagnosticClient option to the driver functions for the CFRefCountChecker and the GRSimpleVals analysis. Both analyses now accept a "-o" argument from the driver that specifies where HTML reports should be dumped. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48989 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
2008-03-28Added skeleton checking for NSString's method initWithFormat: (do not pass ↵Ted Kremenek
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". git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48917 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-27Expanded NSString checking to check for nil for a few more methods.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48898 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-27Add line SourceLocation to NSString checks.Ted Kremenek
Added test case to test warning about passing 'nil' to NSString's compare: method. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48896 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
2008-03-27Add creation of BasicObjCFoundationChecks when running GRSimpleVals from the ↵Ted Kremenek
driver. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48886 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
2008-03-27PathDiagnosticPiece no longer contains a vector of strings; just one string.Ted Kremenek
PathDiagnostic no longer contains a diagnostic ID or diagnostic level. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48864 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-27Added classes "PathDiagnosticPiece", "PathDiagnostic", and ↵Ted Kremenek
"PathDiagnosticClient", which encapsulate diagnostic reporting for paths. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48861 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
2008-03-25GRSimple analysis now outputs additional diagnostic warnings aboutTed Kremenek
passing an uninitialized value to a message expresion. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48776 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
2008-03-22Changed merge operation for uninitialized values analysis to "intersect" ↵Ted Kremenek
(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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48689 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
2008-03-20LiveVariables analysis now uses intersect for the merge of block-level ↵Ted Kremenek
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48618 91177308-0d34-0410-b5e6-96231b3b80d8

logic. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48468 91177308-0d34-0410-b5e6-96231b3b80d8
