* New API to set default thread attributesSiddhesh Poyarekar2013-06-151-0/+23
| | | | | | | This patch introduces two new convenience functions to set the default thread attributes used for creating threads. This allows a programmer to set the default thread attributes just once in a process and then run pthread_create without additional attributes.
* Set fast unaligned load flag for new Intel microarchitectureLiubov Dmitrieva2013-06-141-0/+5
| | | | | | | | | I have small patch for new Intel Silvermont machines. http://newsroom.intel.com/community/intel_newsroom/blog/2013/05/06/intel-launches-low-power-high-performance-silvermont-microarchitecture I checked this on my machine and see that strcpy, ... unaligned versions are faster than ssse3 versions.
* Add rtld-memset.S for x86_64Siddhesh Poyarekar2013-06-151-0/+7
| | | | | | Resolves: BZ #15627 Add an assembler version of rtld-memset to avoid using SSE registers.

* Improve precision of clock() function on LinuxSiddhesh Poyarekar2013-06-131-0/+6
| | | | | | | Resolves #12515. Use CLOCK_PROCESS_CPUTIME_ID instead of times to get better precision in the value returned by clock.
* Fix unsafe compiler optimizationAdhemerval Zanella2013-06-121-0/+8
| | | | | | | | GCC 4.8 enables -ftree-loop-distribute-patterns at -O3 by default and this optimization may transform loops into memset/memmove calls. Without proper handling this may generate unexpected PLT calls on GLIBC. This patch fixes by create memset/memmove alias to internal GLIBC __GI_memset/__GI_memmove symbols.
* Make more libm tests condition exceptions tests with math-tests.h.Joseph Myers2013-06-121-0/+12

* Set/restore rounding mode only when neededSiddhesh Poyarekar2013-06-121-0/+49
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The most common use case of math functions is with default rounding mode, i.e. rounding to nearest. Setting and restoring rounding mode is an unnecessary overhead for this, so I've added support for a context, which does the set/restore only if the FP status needs a change. The code is written such that only x86 uses these. Other architectures should be unaffected by it, but would definitely benefit if the set/restore has as much overhead relative to the rest of the code, as the x86 bits do. Here's a summary of the performance improvement due to these improvements; I've only mentioned functions that use the set/restore and have benchmark inputs for x86_64: Before: cos(): ITERS:4.69335e+08: TOTAL:28884.6Mcy, MAX:4080.28cy, MIN:57.562cy, 16248.6 calls/Mcy exp(): ITERS:4.47604e+08: TOTAL:28796.2Mcy, MAX:207.721cy, MIN:62.385cy, 15543.9 calls/Mcy pow(): ITERS:1.63485e+08: TOTAL:28879.9Mcy, MAX:362.255cy, MIN:172.469cy, 5660.86 calls/Mcy sin(): ITERS:3.89578e+08: TOTAL:28900Mcy, MAX:704.859cy, MIN:47.583cy, 13480.2 calls/Mcy tan(): ITERS:7.0971e+07: TOTAL:28902.2Mcy, MAX:1357.79cy, MIN:388.58cy, 2455.55 calls/Mcy After: cos(): ITERS:6.0014e+08: TOTAL:28875.9Mcy, MAX:364.283cy, MIN:45.716cy, 20783.4 calls/Mcy exp(): ITERS:5.48578e+08: TOTAL:28764.9Mcy, MAX:191.617cy, MIN:51.011cy, 19071.1 calls/Mcy pow(): ITERS:1.70013e+08: TOTAL:28873.6Mcy, MAX:689.522cy, MIN:163.989cy, 5888.18 calls/Mcy sin(): ITERS:4.64079e+08: TOTAL:28891.5Mcy, MAX:6959.3cy, MIN:36.189cy, 16062.8 calls/Mcy tan(): ITERS:7.2354e+07: TOTAL:28898.9Mcy, MAX:1295.57cy, MIN:380.698cy, 2503.7 calls/Mcy So the improvements are: cos: 27.9089% exp: 22.6919% pow: 4.01564% sin: 19.1585% tan: 1.96086% The downside of the change is that it will have an adverse performance impact on non-default rounding modes, but I think the tradeoff is justified.
* Convert iso-639.def to utf-8Siddhesh Poyarekar2013-06-111-0/+4

* Add exception information to math-tests.h and use it in libm-test.inc.Joseph Myers2013-06-111-0/+9
|
* Port remaining string benchmarksSiddhesh Poyarekar2013-06-111-0/+12
| | | | | There were a few more string benchmarks (strcpy_chk and stpcpy_check) in the debug directory that needed to be ported over.

* Remove performance-related bits from string testsSiddhesh Poyarekar2013-06-111-0/+53
|
* Copy over string performance tests into benchtestsSiddhesh Poyarekar2013-06-111-0/+62
| | | | | Copy over already existing string performance tests into benchtests. Bits not related to performance measurements have been omitted.
* Begin porting string performance tests to benchtestsSiddhesh Poyarekar2013-06-111-0/+13
| | | | | | | | | | | | | | This is the initial support for string function performance tests, along with copying tests for memcpy and memcpy-ifunc as proof of concept. The string function benchmarks perform operations at different alignments and for different sizes and compare performance between plain operations and the optimized string operations. Due to this their output is incompatible with the function benchmarks where we're interested in fastest time, throughput, etc. In future, the correctness checks in the benchmark tests can be removed. Same goes for the performance measurements in the string/test-*.

* Update Chinese (traditional) translation from translation projectAndreas Jaeger2013-06-111-0/+5
|
* Fix symbol definitions for __clock_* functionsSiddhesh Poyarekar2013-06-111-0/+22
| | | | | | __clock_gettime and other __clock_* functions could result in an extra PLT reference within libc.so if it actually gets used. None of the code currently uses them, which is why this probably went unnoticed.

|
* Avoid overwriting earlier flags in CPPFLAGS-nonlib in benchtestsSiddhesh Poyarekar2013-06-101-0/+5
| | | | | | When setting BENCH_DURATION in CPPFLAGS-nonlib, append to the variable instead of assigning to it, to avoid overwriting earlier set flags, notably the -DNOT_IN_libc=1 flag.
