2013-06-01avutil/crc: Dont limit CRC32 standard tablesJames Almer
Currently, standard tables like AV_CRC_32_IEEE and such are being generated (or provided in case the user compiles with hardcoded tables) with only 257 elements. We're missing a considerable boost in performance by not making them with a size of 1024 elements instead. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

2013-05-24lavu/opencl: remove semi-colon from macro.Clément Bœsch
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
2013-05-24Move get_logical_cpus() from lavc/pthread to lavu/cpu.Anton Khirnov
It will be useful in lavfi, and could conceivably be useful to the user applications as well.

2013-05-20md5: optimize second round by using 4-operation form of G()Giorgio Vazzana
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>
