git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@89734 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-23Clean up the Checker API a little more, resolving some hidden bugsTed Kremenek
along the way. Important changes: 1) To generate a sink node, use GenerateSink(); GenerateNode() is for generating regular transitions. This makes the API clearer and also allows us to use the 'bool' option to GenerateNode() for a different purpose. 2) GenerateNode() now automatically adds the generated node to the destination ExplodedNodeSet (autotransition) unless the client specifies otherwise with a bool flag. Several checkers did not call 'addTransition()' after calling 'GenerateNode()', causing the simulation path to be prematurely culled when a non-fail stop bug was encountered. 3) Add variants of GenerateNode()/GenerateSink() that take neither a Stmt* or a GRState*; most callers of GenerateNode() just pass in the same Stmt* as provided when the CheckerContext object is created; we can just use that the majority of the time. This cleanup also allows us to potentially coelesce the APIs for evaluating branches and end-of-paths (which currently directly use builders). 4) addTransition() no longer needs to be called except for a few cases. We now have a variant of addTransition() that takes a GRState*; this allows one to propagate the updated state without caring about generating a new node explicitly. This nicely cleaned up a bunch of cases that called autoTransition() with a bunch of conditional logic surround the call (that common logic has now been swallowed up by addTransition() itself). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@89707 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-21Pull BadCallChecker int UndefinedArgChecker, and have UndefinedArgChecker ↵Ted Kremenek
also handled undefined receivers in message expressions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@89524 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-21More checker refactoring. Passing undefined values in a message expression ↵Ted Kremenek
is now handled by UndefinedArgChecker. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@89519 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-14Change *BugReport constructors to take StringRefs.Benjamin Kramer
- Eliminates many calls to std::string.c_str() - Fixes an invalid read in ReturnStackAddressChecker due to an unsafe call to StringRef.data() which doesn't guarantee null-termination. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@88779 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-11Remove public headers for UndefinedArgChecker, AttrNonNullChecker, and ↵Ted Kremenek
BadCallChecker, making their implementations completely private. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86809 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-06Minor cleanup: use BuiltinBug (which will soon be renamed) for ↵Ted Kremenek
DeferenceChecker and friends so that they always report the same bug type. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86208 91177308-0d34-0410-b5e6-96231b3b80d8
