Jules Villard 0f1bdf664d [clang] static data members are external globals unless defined in the file ... Summary: The issue is with classes defining static data members: ``` $ cat foo.h struct A { static int foo; }; $ cat foo.cpp #include "foo.h" int A::foo = 12; int f() { return A::foo; // should see A::foo as defined in this translation unit $ cat bar.cpp #include "foo.h" void g() { return A::foo; // should see A::foo defined externally ``` Previously, both foo.cpp and bar.cpp would see `A::foo` as defined within their translation unit, because it comes from the header. This is wrong, and static data members should be treated as extern unless they're defined in the same file. This doesn't change much except for frontend tests. SIOF FP fix in the next diff. update-submodule: facebook-clang-plugins Reviewed By: da319 Differential Revision: D6221744 fbshipit-source-id: bef88fd		7 years ago
