* Expose the name of the checker producing each diagnostic message.Alexander Kornienko2014-02-111-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | Summary: In clang-tidy we'd like to know the name of the checker producing each diagnostic message. PathDiagnostic has BugType and Category fields, which are both arbitrary human-readable strings, but we need to know the exact name of the checker in the form that can be used in the CheckersControlList option to enable/disable the specific checker. This patch adds the CheckName field to the CheckerBase class, and sets it in the CheckerManager::registerChecker() method, which gets them from the CheckerRegistry. Checkers that implement multiple checks have to store the names of each check in the respective registerXXXChecker method.

* Replacing calls to getAttr with calls to hasAttr for clarity. No functional ↵Aaron Ballman2013-12-191-1/+1

* [analyzer] Apply the suppression rules to the nil receiver only if the value ↵Anna Zaks2013-03-281-1/+2
| | | | | | | | | | | | | | participates in the computation of the nil we warn about. We should only suppress a bug report if the IDCed or null returned nil value is directly related to the value we are warning about. This was not the case for nil receivers - we would suppress a bug report that had an IDCed nil receiver on the path regardless of how it’s related to the warning. 1) Thread EnableNullFPSuppression parameter through the visitors to differentiate between tracking the value which is directly responsible for the bug and other values that visitors are tracking (ex: general tracking of nil receivers). 2) in trackNullOrUndef specifically address the case when a value of the message send is nil due to the receiver being nil. llvm-svn: 178309

* Change references to 'const ProgramState *' to typedef 'ProgramStateRef'.Ted Kremenek2012-01-261-1/+1
| | | | | | | | At this point this is largely cosmetic, but it opens the door to replace ProgramStateRef with a smart pointer that more eagerly acts in the role of reclaiming unused ProgramState objects. llvm-svn: 149081
* [analyzer] Make the entries in 'Environment' context-sensitive by making ↵Ted Kremenek2012-01-061-1/+2
| | | | | | | | | | | | | | | | | | entries map from (Stmt*,LocationContext*) pairs to SVals instead of Stmt* to SVals. This is needed to support basic IPA via inlining. Without this, we cannot tell if a Stmt* binding is part of the current analysis scope (StackFrameContext) or part of a parent context. This change introduces an uglification of the use of getSVal(), and thus takes two steps forward and one step back. There are also potential performance implications of enlarging the Environment. Both can be addressed going forward by refactoring the APIs and optimizing the internal representation of Environment. This patch mainly introduces the functionality upon when we want to build upon (and clean up). llvm-svn: 147688

And move the parent(BugReporterVisitor) there as well. 2) Remove the registerXXXVisitor functions - the Visitor constructors/getters can be used now to create the object. One exception is registerVarDeclsLastStore(), which registers more then one visitor, so make it static member of FindLastStoreBRVisitor. 3) Modify all the checkers to use the new API. llvm-svn: 138126
