Gabor Horvath	d1abcf799e	[analyzer] Improve pointer arithmetic checker. This patch is intended to improve pointer arithmetic checker. From now on it only warns when the pointer arithmetic is likely to cause an error. For example when the pointer points to a single object, or an array of derived types. Differential Revision: http://reviews.llvm.org/D14203 llvm-svn: 261632	2016-02-23 12:34:39 +00:00
Anna Zaks	bac964e14f	[analyzer] Use a more generic MemRegion.getAsOffset to evaluate bin operators on MemRegions In addition to enabling more code reuse, this suppresses some false positives by allowing us to compare an element region to its base. See the ptr-arith.cpp test cases for an example. llvm-svn: 182780	2013-05-28 17:31:43 +00:00

In addition to enabling more code reuse, this suppresses some false positives by allowing us to
compare an element region to its base. See the ptr-arith.cpp test cases for an example.
