Martin Storsjö	be7952b5c3	arm: Only output eabi attributes if building for ELF This matches the other eabi attribute in the same file. This is required in order to build for arm/hardfloat with other object file formats than ELF. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago

Clément Bœsch	cf6ed1f129	lavu/opencl: remove semi-colon from macro. 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	12 years ago
Anton Khirnov	2a6eaeaa85	Move get_logical_cpus() from lavc/pthread to lavu/cpu. It will be useful in lavfi, and could conceivably be useful to the user applications as well.	12 years ago

Giorgio Vazzana	d0a34aeedf	md5: optimize second round by using 4-operation form of G() 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>	12 years ago
