| | | | | | 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.

* Add versions of wcscpy, wcschr, wcsrchr for power6/power7.Will Schmidt2012-08-226-0/+283
| | | | | | | | | | | | | | 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.
* [Powerpc] Tune/optimize powerpc{32,64}/power7/memchr.S.Will Schmidt2012-08-212-44/+119
| | | | | | | | | | | | 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.

* Manual for platform-specific features and new __ppc_get_timebase inline.Tulio Magno Quites Machado Filho2012-06-043-0/+98
| | | | | | | | | [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.

* [PowerPC] Remove -ftree-loop-linear from MakefilesTulio Magno Quites Machado Filho2012-05-184-6/+6
| | | | | | | | | | | | | | | | In the past the "-ftree-loop-linear" switch provided a measurable improvement in performance for certain functions. At some point it was assigned as the responsibility of Graphite in GCC. It has been found that even with Graphite enabled these flags no longer perform any appreciable improvement over the baseline. Graphite now has some open bugs which need to be fixed in order for it to provide measurable performance improvements but it lacks active development. As a result some compiler distributors may disable Graphite. If Graphite is disabled then building GLIBC will fail if the "-ftree-loop-linear" switch is used. This patch removes the use of "-ftree-loop-linear" as unnecessary.
