The first patch changes the C++ testsuite to run in C++14 mode as well as
C++98 and C++11.
As a result, specifying { target c++11 } matches c++11 and c++1y mode.
{ target c++1y } matches c++1y only, and { target c++98 } matches c++98 only.
Is that correct ?
Everything is intended to mean "C++XX and up" now. But c++98 isn't
defined, since it would be meaningless. And so it isn't used in tests
either. So for c++98 only you can use c++98_only or { ! c++11 }.
The second patch splits up the running of dg.exp to avoid it running longer
than libstdc++ in parallel testing.
Incidentally, how does it affect testing time ?
On a highly parallel system, it doesn't affect testing time because one
of the chunks of libstdc++ tests still takes longer than any of the
chunks of g++ tests.
