Artem Dergachev	eb71c0c961	[analyzer] SmartPtrModeling: Fix a null dereference. Don't crash when trying to model a call in which the callee is unknown in compile time, eg. a pointer-to-member call. Differential Revision: https://reviews.llvm.org/D61285 llvm-svn: 359530	2019-04-30 03:00:57 +00:00
Artem Dergachev	8c6119a442	[analyzer] PR41269: Add a bit of C++ smart pointer modeling. Implement cplusplus.SmartPtrModeling, a new checker that doesn't emit any warnings but models methods of smart pointers more precisely. For now the only thing it does is make `(bool) P` return false when `P` is a freshly moved pointer. This addresses a false positive in the use-after-move-checker.

Don't crash when trying to model a call in which the callee is unknown
in compile time, eg. a pointer-to-member call.

Implement cplusplus.SmartPtrModeling, a new checker that doesn't
emit any warnings but models methods of smart pointers more precisely.

For now the only thing it does is make `(bool) P` return false when `P`
is a freshly moved pointer. This addresses a false positive in the
