Ted Kremenek fabfb4677d Do not highlight bogus ranges for leaks.

Ted Kremenek f20e2285c9 More cleanups with ObjCQualifiedIdType in the static analyzer.

Ted Kremenek 20d8006e93 Teach more of the static analyzer about ObjCQualifiedIdType.

Ted Kremenek 575f24ef73 Gracefully handle when the receiver of a message expression is not a pointer type.

Ted Kremenek 31484b2477 Generalize caching mechanism for bugs reports. Now individual BugTypes 
can decide the policy on how to cache related bugs.  This allows us to
properly to handle warning about multiple leaks in the same location in the
ref count checker (not yet done).

Ted Kremenek cffe635699 Simplified internal logic of BugReporter, consolidating EmitWarning and 
EmitPathWarning into one method.  We now properly handle emitting warnings
without a PathDiagnosticClient when the warning does not involve a particular
statement.

Ted Kremenek 7e15130dc9 Hooked up the dead-store checker to the BugReporter interface. Now dead-store 
warnings are emitted as part of the warnings registered by GRSimpleVals.

Ted Kremenek 83744ddbd9 Fixed regressions in error reporting due to copy-paste errors (using the "begin" 
iterator instead of "end") and not implementing "getDescription()" for Nil
argument checks.

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.

Ted Kremenek d1a2efadba Added investigate patch for an occasionally failing assertion (heisenbug?) 
llvm-svn: 49193
 2008-04-03 21:44:24 +00:00
Ted Kremenek cb2dc8eca5 Hooked up GRSimpleAPICheck and the simple Objective-C Foundation checks to use 
the new BugReporter interface.

 2008-04-03 17:57:38 +00:00
Ted Kremenek c719424caa 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".

llvm-svn: 48917
 2008-03-28 16:09:38 +00:00
Ted Kremenek 276278e5d2 Expanded NSString checking to check for nil for a few more methods. 
llvm-svn: 48898
 2008-03-27 22:05:32 +00:00
Ted Kremenek 2e4e7ccb22 Add line SourceLocation to NSString checks. 
Added test case to test warning about passing 'nil' to NSString's compare: method.

llvm-svn: 48896
 2008-03-27 21:23:57 +00:00
Ted Kremenek 27156c8c9f Hooked up initial NSString interface checking to GRSimpleVals. 
llvm-svn: 48895
 2008-03-27 21:15:17 +00:00
Ted Kremenek a4d60b6de3 Add creation of BasicObjCFoundationChecks when running GRSimpleVals from the driver. 
llvm-svn: 48886
 2008-03-27 17:17:22 +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.
