Siddhesh Poyarekar 1e3803454e Revert configurable mantissa patch
Reverts d22ca8cdfb

since it is severely broken on 32-bit.
2013-03-15 23:18:51 +05:30
Siddhesh Poyarekar d22ca8cdfb Make mantissa type configurable
This allows the default mantissa to be integral, with powerpc
overriding it to take advantage of its FPUs.

Tulio Magno Quites Machado Filho d7d08bdede Direct __ppc_get_timebase to __builtin_ppc_get_timebase for GCC 4.8+.
Adapts __ppc_get_timebase to the upcoming GCC 4.8 that provides
__builtin_ppc_get_timebase.  Building applicationns with previous
versions of GCC will continue to use the internal implementation.

Will Schmidt 15d0da8cb3 Add versions of wcscpy, wcschr, wcsrchr for power6/power7.
Initially based on the versions found in wcsmbs/* ; these files have
been changed by hand unrolling, and adding some additional variables
to allow some read-ahead to occur, which then relieves some of the
wait-for-increment/wait-for-load/wait-for-compare-results pressure
that was slowing down every iteration through the while-loop.

For 64-bit Power7, These changes give an approx 20% throughput boost
for the wcschr and wcsrchr functions; and approx 40% boost for the
wcscpy function.  32-bit improvements appear to be slightly better
with ~ %30 and ~ %45 respectively.  Results for Power6 closely match
those for power7.
