Add some more PS4 driver settings related to rtti and exceptions. Summary: The PS4 defaults to -fno-rtti, and has to have rtti enabled when enabling exceptions. This commit makes clang add the -fno-rtti by default on the PS4, unless -frtti was passed in. It also diagnoses misuses for the PS4: - Exceptions need rtti. Warn and enable rtti if no rtti flag was passed, error if -fno-rtti was passed. I also added a more general warning for when -fno-rtti is the default (currently it's only on the PS4) and the vptr sanitizer is on. Fixed a few tests, due to different flag order when passing cc1 arguments. Reviewers: chandlerc Subscribers: cfe-commits Differential Revision: http://reviews.llvm.org/D7250 llvm-svn: 227518
