Zhongxing Xu b166712d02 Add undefined array subscript checker.

Zhongxing Xu 4f7759a339 Reimplement out-of-bound array access checker with the new checker interface.
Now only one test case is XFAIL'ed.

Ted Kremenek 4325315935 Remove public headers for UndefinedArgChecker, AttrNonNullChecker, and BadCallChecker, making their implementations completely private.

Ted Kremenek 5e1f78aeb1 Refactor DereferenceChecker to use only the new Checker API instead of
the old builder API.  This percolated a bunch of changes up to the
Checker class (where CheckLocation has been renamed VisitLocation) and
GRExprEngine.  ProgramPoint now has the notion of a "LocationCheck"
point (with PreLoad and PreStore respectively), and a bunch of the old
ProgramPoints that are no longer used have been removed.

Zhongxing Xu ab0e27ff0c Add check for pointer arithmetic on non-array variables.

2009-11-09 13:23:31 +00:00
Zhongxing Xu f06c684a33 Add checker for CWE-588: Attempt to Access Child of a Non-structure Pointer.

2009-11-09 08:07:38 +00:00
Zhongxing Xu 6c306c8b89 Add checker for CWE-587: Assignment of a Fixed Address to a Pointer.

Zhongxing Xu 86b1e01c13 Add checker for CWE-469: Use of Pointer Subtraction to Determine Size. This
checker does not build sink nodes. Because svaluator computes an unknown value
for the subtraction now.

Ted Kremenek 795c611cfa Make the VLASizeChecker implementation private, and its creation only known to GRExprEngineInternalChecks.cpp.

Ted Kremenek 53a70c055d Make the implementation of DivZeroChecker private.

Zhongxing Xu 167bce9cf1 Add a checker for CWE-466: Return of Pointer Value Outside of Expected Range.

2009-11-06 13:30:44 +00:00
Ted Kremenek bee01e5b61 static analyzer: refactor checking logic for returning the address of a stack variable or a garbage
value into their own respective subclasses of Checker (and put them in .cpp files where their
implementation details are hidden from GRExprEngine).
