* Merge commit '2a6eaeaa85d17b27ee0dd449183ec197c35c9675'Michael Niedermayer2013-05-24
|\ | | | | | | | | | | | | | | | | | | | | | | | | | | * commit '2a6eaeaa85d17b27ee0dd449183ec197c35c9675': Move get_logical_cpus() from lavc/pthread to lavu/cpu. Conflicts: doc/APIchanges libavcodec/pthread.c libavutil/cpu.c libavutil/cpu.h libavutil/version.h Merged-by: Michael Niedermayer <michaelni@gmx.at>
| * Move get_logical_cpus() from lavc/pthread to lavu/cpu.Anton Khirnov2013-05-24
| | | | | | | | | | It will be useful in lavfi, and could conceivably be useful to the user applications as well.
| * pixdesc: mark gray8 as pseudopalAnton Khirnov2013-05-22
| | | | | | | | | | | | | | Many functions treat it as such already. Fixes Bug 499. CC:libav-stable@libav.org
* | lavu/opencl: remove semi-colon from macro.Clément Bœsch2013-05-24
| | | | | | | | | | | | | | | | Fixes compilation when the macros are empty and the label above ends up containing no statement. Also makes usage of these macro consistent (some already have a semi colon, some others don't). Fixes Ticket #2603

* | md5: optimize second round by using 4-operation form of G()Giorgio Vazzana2013-05-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 4-operation form is preferred over 3-operation because it breaks a long dependency chain, thus allowing a superscalar processor to execute more operations in parallel. The idea was taken from: http://www.zorinaq.com/papers/md5-amd64.html AMD Athlon(tm) II X3 450 Processor, x86_64 $ for i in $(seq 1 4); do ./avutil_md5_test2; done size: 1048576 runs: 1024 time: 5.821 +- 0.019 size: 1048576 runs: 1024 time: 5.822 +- 0.019 size: 1048576 runs: 1024 time: 5.841 +- 0.018 size: 1048576 runs: 1024 time: 5.821 +- 0.018 $ for i in $(seq 1 4); do ./avutil_md5_test2; done size: 1048576 runs: 1024 time: 5.646 +- 0.019 size: 1048576 runs: 1024 time: 5.646 +- 0.018 size: 1048576 runs: 1024 time: 5.642 +- 0.019 size: 1048576 runs: 1024 time: 5.641 +- 0.019 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
