| 2013-06-24 | PowerPC: Enable POWER8 platform sans hwcap bits. | Ryan S. Arnold | |
| 2013-06-07 | Avoid use of "register" as optimization hint. | Joseph Myers | |
| 2013-06-06 | Fix leading whitespaces. | Ondrej Bilka | |
| 2013-06-05 | Remove trailing whitespace. | Joseph Myers | |
| 2013-05-29 | Avoid crashing in LD_DEBUG when program name is unavailable | Siddhesh Poyarekar | |
| Resolves: #15465 The program name may be unavailable if the user application tampers with argc and argv[]. Some parts of the dynamic linker caters for this while others don't, so this patch consolidates the check and fallback into a single macro and updates all users. | |||
| 2013-04-26 | PowerPC: modf optimization fix | Adhemerval Zanella | |
| This patch fix the 3c0265394d9ffedff2b0de508602dc52e077ce5c commits by correctly setting minimum architecture for modf PPC optimization to power5+ instead of power5 (since only on power5+ round/ceil will be inline to inline assembly). | |||
| 2013-04-23 | PowerPC: modf optimization | Adhemerval Zanella | |
| This patch implements modf/modff optimization for POWER by focus on FP operations instead of relying in integer ones. | |||
| 2013-04-01 | PowerPC: remove branch prediction from rint implementation | Adhemerval Zanella | |
| The branch prediction hints is actually hurts performance in this case. The assembly implementation make two assumptions: 1. 'fabs (x) < 2^52' is unlikely and 2. 'x > 0.0' is unlike (if 1. is true). Since it a general floating point function, expected input is not bounded and then it is better to let the hardware handle the branches. | |||
| 2013-03-28 | PowerPC: .eh_frame info in crt1.o isn't useful and triggers gold bug 14675. | Alan Modra | |
| The .eh_frame info in crt1.o isn't useful and this patch prevents it from being generated on PowerPC. It triggers the following gold bug: http://sourceware.org/bugzilla/show_bug.cgi?id=14675 | |||

| 2013-01-04 | Fix build failure on power4 processors | Siddhesh Poyarekar | |
| The power4-specific mpa.c depended on some global variables that were removed by earlier patches. Also, it did not define mpone and mptwo. | |||
| 2013-01-02 | Update copyright notices with scripts/update-copyrights. | Joseph Myers | |
| 2013-01-01 | Add script to update copyright notices and reformat some to facilitate its use. | Joseph Myers | |
| 2012-11-01 | Put __NO_FPRS__ around floating point opcodes in powerpc32/dl-trampoline.S. | Sebastan Andrzej Siewior | |
| 2012-10-09 | Add missing magic to GLIBC_PROVIDES. | Roland McGrath | |
| 2012-08-22 | Add 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. | |||
