re PR target/54686 (std::abs (long long) resorts to std::abs (double) if llabs is absent)
2012-10-05 Marc Glisse <marc.glisse@inria.fr>
PR libstdc++/54686
* include/c_global/cstdlib (abs(long long)): Define with
__builtin_llabs when we have long long.
(abs(long)): Use __builtin_labs.
(abs(__int128)): Define when we have __int128.
