RFC: stop using _ to separate ObjC/C++ class name from method in Typ.Procname.to_string Reviewed By: jvillard Differential Revision: D14736442 fbshipit-source-id: 500df354b

[infer] Translate casting expressions of integer pointers Summary: It enables the translation of casting expression. As of now, it translates only the castings of pointers to integer types, in order to avoid too much of change, which may mess the checkers up.

[tests] record error bucket in expected output Summary: It's useful to test that the bucket a given error is classified as doesn't change over time without notice. This records the bucket for *all* the tests, even though some never produce a bucket. This is to be on the safe size instead of risking to forget adding the bucket information when the test changes, or when copy/pasting from a test that doesn't have buckets to one that does. The implementation is pretty crude: it greps the beginning of the qualifier string for a `[bucket]`. Reviewed By: mbouaziz Differential Revision: D8236393 fbshipit-source-id: b3b1eb9

[frontend] Fix capture init for cpp lambdas Summary: We were missing assignment to captured variables with initializers. Consider the following example: ``` S* update_inside_lambda_capture_and_init(S* s) { S* object = nullptr; auto f = [& o = object](S* s) { o = s; }; f(s); return object; } ``` which was translated to ``` VARIABLE_DECLARED(o:S*&); *&o:S*&=&object *&f =(_fun...lambda..._operator(),([by ref]&o &o:S*&)) ``` However, we want to capture `o` (which is an address of `object`), rather `&o` in closure. After the diff ``` VARIABLE_DECLARED(o:S*&); *&o:S*&=&object n$7=*&o:S*& *&f =(_fun...lambda..._operator(),([by ref]n$7 &o:S*&)) ``` Reviewed By: jvillard Differential Revision: D23567346 fbshipit-source-id: 20f77acc2

[pre-analysis] Add models for `no_return` and handle throw-catch better Summary: - Add `no_return` models for Java's `exit(...)` methods (can be extended further later on) - handle throw-catch better by short-cutting throw nodes to not exit node but to all **catch nodes** that are reachable by the node. If there is no catch node, we short-cut to the exit node as before. This removes a FP from deadstore tests because before we simply were not able to handle CF from throw-> catch nodes at all.

[dead store] Removed special case for constexpr in lambda captures Summary: We had a special case for fixing false positives on constexpr implicitly captured by lambdas. However, we do not report dead stores on constexpr anymore, hence, do not need the special case anymore. Moreover, the special case was not only capturing constexpr in lambdas, but also any variables which type had `const` (see new test `capture_const_bad` which was not being reported before this diff) Reviewed By: mbouaziz Differential Revision: D9654848 fbshipit-source-id: 882fd2804
