* 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>
