Daniel Dunbar f3502dbc14 [LLVM up] Update for raw_fd_ostream change. This fixes a FIXME that 
the Backend output should be done in binary mode.
 - I'd appreciate it if someone who has a Windows build could verify
   this.

Ted Kremenek f0673e4eb6 Change implementation of NSError** coding-style check to be invoked at the end of the retain/release analysis. 
llvm-svn: 56312
 2008-09-18 21:25:13 +00:00
Ted Kremenek fc3abeb1e5 Implemented one of the checks requested in PR 2600: 
"Method accepting NSError** argument should have non-void return value to indicate that an error occurred."

Test case written, but the header needs to be delta-debugged reduced.  Will commit shortly.

 2008-08-28 05:02:09 +00:00
Ted Kremenek 266ec3fb4e Automatically execute ubiviz. 
Cleanup ubigraph files when don't drawing the graphs.

Ted Kremenek c8288b408a Ubigraph-rendered ExplodedGraphs now have arrows and are oriented downward. 
llvm-svn: 55446
 2008-08-27 22:46:55 +00:00
Ted Kremenek d461d7ad7e Added Ubigraph visualization for the static analyzer (this is pretty alpha quality).

Ted Kremenek 9898028742 Fix regression when invoking the MissingDealloc analysis: disable this check when in -fobjc-gc-only mode. 
llvm-svn: 54319

Ted Kremenek 3b28f4911c Add prototype implementation of unused ivar check.

Ted Kremenek 1f352db96a Moved registration of basic path-sensitive checks from GRSimpleVals.cpp to GRExprEngineInternalChecks.cpp. 
llvm-svn: 53909
 2008-07-22 16:21:24 +00:00
Ted Kremenek fd7efdf20d Provide an "Analysis Scope" for Analyses so checks can either be run on code declarations (bodies) or Objective-C @implementation blocks. 
llvm-svn: 53584
 2008-07-15 00:46:02 +00:00
Ted Kremenek 3063b73773 Break off declaration of Analysis enum into Analyses.def. The driver options in 
clang.cpp now #include these definitions to create the command line options, and
AnalysisConsumer #includes this file to generate the switch statement to create
actions.

Renamed -check-objc-methodsigs to -warn-objc-methodsigs.

The "missing -dealloc" check is now optional: -warn-objc-missing-dealloc

llvm-svn: 53575
 2008-07-14 23:41:13 +00:00
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.

Ted Kremenek e66ca6f35a For the -dealloc checker, check the LangOptions to determine whether or not the code is compiled with GC.

 2008-07-03 14:35:01 +00:00
Ted Kremenek 1d3c797c90 Have BugReporter::getCFG and BugReporter::getLiveVariables returns pointers instead of references, because they can both fail 
on functions we cannot construct full CFGs for yet.

llvm-svn: 53081
 2008-07-03 05:26:14 +00:00
Ted Kremenek 0e7d25233e Added static analysis check to see if a subclass of NSObject implements -dealloc, and whether or not that implementation calls [super dealloc]. 
llvm-svn: 53075
 2008-07-03 04:29:21 +00:00
Ted Kremenek c7efb536d5 Unify the code path for the Dead Stores checker to always use the BugReporter interface. 
llvm-svn: 53054
 2008-07-02 23:16:33 +00:00
Ted Kremenek b1d0118a1a Refactored some of the BugReporter interface so that data such as the ASTContext&, PathDiagnosticClient*, can be provided by an external source. 
Split BugReporter into BugReporter and GRBugReporter so checkers not based on GRExprEngine can still use the BugReporter mechanism.

llvm-svn: 53048
 2008-07-02 21:24:01 +00:00
Ted Kremenek 125d4a3b2d GRExprEngine now expects the LiveVariables information to be provided by its creator. 
This allows an optimization in AnalysisConsumer where the same LiveVariables information is used between multiple analyses.

llvm-svn: 53046
 2008-07-02 20:13:38 +00:00
Ted Kremenek d8ca1f6dd9 Added version of CheckDeadStores that accepts a client-provided LiveVariables object. 
Modified the DeadStores logic in AnalysisConsumer.cpp to use the LiveVariables object created by the AnalysisManager.

llvm-svn: 53043
 2008-07-02 18:39:20 +00:00
Ted Kremenek f992cfb4ab Moved logic for -dump-cfg and -view-cfg into AnalysisConsumer. 
Renamed -dump-cfg to -cfg-dump, and -view-cfg to -cfg-view.  This naming better matches the same options for asts (e.g. -ast-dump).

llvm-svn: 53041
 2008-07-02 18:23:21 +00:00
Ted Kremenek bdbe6130f4 Move -dump-live-variables logic to AnalysisConsumer. 
llvm-svn: 53039
 2008-07-02 18:11:29 +00:00
Ted Kremenek 71ac83246f Migrate CheckerConsumer diagnostics to the new AnalysisConsumer interface. 
Remove CheckerConsumer.

llvm-svn: 53029

Ted Kremenek becec2cbbc Move logic for "-checker-simple" to the new AnalysisConsumer interface. 
llvm-svn: 53028
 2008-07-02 16:35:50 +00:00
Ted Kremenek 8e631a0267 Migrated driver logic for running the CF retain/release checker over to the new AnalysisConsumer interface. 
llvm-svn: 53002
 2008-07-02 00:44:58 +00:00
Ted Kremenek f0413bfcda Added AnalysisConsumer, a meta-level ASTConsumer class to drive various 
analyses. This potentially is the primordial origins of a Clang-equivalent
"PassManager".

The new AnalysisConsumer interface allows multiple analyses to be run from a
single invocation of Clang.

Migrated the logic of "-warn-dead-stores" and "-warn-uninit-values" to use the
new AnalysisConsumer interface. The new interface results in a significant code
reduction to incorporate an analysis into the Driver.

Updated a test case to (correctly) acknowledge that it contains a dead store
(this check wasn't being performed because it was previously masked by
-warn-uninit-values).
