Not to forget that Charles Li did a pile of work over the past year or so
to tidy up a lot of the tests.  Given that the PS4 target already defaults
to C++11, I should hope there would be little left to do.

Right, and indeed we have buildbots that test that a C++11 default works.
So the remaining cleanups would be for C++14-specific issues, which should
be minimal in comparison to the great work Charles did.

I'll see what I can do tomorrow. Hopefully I can at least get some
numbers here by the end of the day. Possibly patches; what's our
preferred solution to failures: fix the code (within reason), or
-std=c++98?



If the difference is interesting, test it in both modes. If the test is
C++98-specific or has uninteresting diagnostic differences, -std=c++98.
