At one point, -fexceptions was a synonym for -fcxx-exceptions. While the driver options still enables cxx-exceptions by default, the cc1 flag is purely about exception tables and this doesn't account for objective C exceptions. Because of this, checking for the cxx_exceptions feature in objective C++ often gives the wrong answer. The cxx_exceptions feature should be based on the -fcxx-exceptions cc1 flag, not -fexceptions. Furthermore, at some point the tests were changed to use cc1 even though they were testing the driver behaviour. We're better off testing both the driver and cc1 here. llvm-svn: 206352
