2012-08-22Add versions of wcscpy, wcschr, wcsrchr for power6/power7.Will Schmidt
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.
2012-08-21[Powerpc] Tune/optimize powerpc{32,64}/power7/memchr.S.Will Schmidt
Assorted tweaking, twisting and tuning to squeeze a few additional cycles out of the memchr code. Changes include bypassing the shift pairs (sld,srd) when they are not required, and unrolling the small_loop that handles short and trailing strings. Per scrollpipe data measuring aligned strings for 64-bit, these changes save between five and eight cycles (9-13% overall) for short strings (<32), Longer aligned strings see slight improvement of 1-3% due to bypassing the shifts and the instruction rearranging.

2012-06-04Manual for platform-specific features and new __ppc_get_timebase inline.Tulio Magno Quites Machado Filho
[BZ #13743] A new class of installed headers has been documented for low-level platform-specific functionality. PowerPC added the first instance with a function to provide time base register access (__ppc_get_timebase). This is required for applications that measure time at high frequencies with high precision that can't afford a syscall.
