Jules Villard c6812df1eb fix infinitely-expanding types in the backend Summary: Simple instance of the problem: analyzing the following program times out. ``` #include <tuple> void foo() { std::tuple<std::tuple<int>> x; } ``` Replacing `std::tuple<std::tuple<int>>` by `std::tuple<int>` makes the analysis terminate. In the AST, both tuple<tuple<int>> and tuple<int> have the same template specialization type: "Pack" (which means we're supposed to go look into the arguments of the template to get their values). This is not information enough and that's the plugin fault. On the backend side, this means that two types have the same Typ.Name.t, namely "std::tuple<_>", so they collide in the tenv. The definition of tuple<tuple<int>> is the one making it into the tenv. One of the fields of the corresponding CxxRecord is of type "tuple<int>", which we see as the same "tuple<_>", which causes the loop. update-submodule: facebook-clang-plugins Reviewed By: mbouaziz Differential Revision: D5775840 fbshipit-source-id: 0528604		7 years ago
