* truehd: add hand-scheduled ARM asm version of mlp_filter_channel.Ben Avison2014-03-26
| | | | | | | | | | | | | | | | | | | | | | | | | Profiling results for overall audio decode and the mlp_filter_channel(_arm) function in particular are as follows: Before After Mean StdDev Mean StdDev Confidence Change 6:2 total 380.4 22.0 370.8 17.0 87.4% +2.6% (insignificant) 6:2 function 60.7 7.2 36.6 8.1 100.0% +65.8% 8:2 total 357.0 17.5 343.2 19.0 97.8% +4.0% (insignificant) 8:2 function 60.3 8.8 37.3 3.8 100.0% +61.8% 6:6 total 717.2 23.2 658.4 15.7 100.0% +8.9% 6:6 function 140.4 12.9 81.5 9.2 100.0% +72.4% 8:8 total 981.9 16.2 896.2 24.5 100.0% +9.6% 8:8 function 193.4 15.0 103.3 11.5 100.0% +87.2% Experiments with adding preload instructions to this function yielded no useful benefit, so these have not been included. The assembly version has also been tested with a fuzz tester to ensure that any combinations of inputs not exercised by my available test streams still generate mathematically identical results to the C version.

* Revert part of r18903:Ramiro Polla2009-05-23
| | | | | | | | | | | | MLP DSP functions x86-optimized. 12.59% overall speedup in x86_32 9.98% overall speedup in x86_64 compared to gcc 4.3.3 It breaks on x86_64 with PIC because the MANGLE macro appends (%%rip), which is not wanted for labels.
