5aeaab7c6d C++: As response to the review comments this commit adds a reference-to-pointer state to AddressFlow. A call to an unwrapper function now adds a pointer -> reference-to-pointer transition, and a ReferenceDereference adds a reference-to-pointer -> pointer transition. 2021-04-12 16:01:01 +02:00

0a86642056 C++: Refactor some side effect generation code 
This change was necessary for my upcoming changes to introduce side effect instructions for indirections of smart pointers. The code to decide which parameters have which side effects appeared in both the IPA constructor for `TTranslatedSideEffect` and in `TranslatedCall`. These two versions didn't quite agree, especially once the `SideEffectFunction` model provides its own side effects instead of the defaults.
The relevant code has now been factored out into `SideEffects.qll`. This queries the model if one exists, and provides default side effects if no model exists. This fixes at least one existing issue, where we were emitting a buffer read side effect for `*this` instead of an indirect read side effect. This accounts for all of the IR diffs in the tests.
