Ben Avison	89135716fd	truehd: add hand-scheduled ARM asm version of ff_mlp_rematrix_channel. ... Profiling results for overall audio decode and the rematrix_channels function in particular are as follows: Before After Mean StdDev Mean StdDev Confidence Change 6:2 total 370.8 17.0 348.8 20.1 99.9% +6.3% 6:2 function 46.4 8.4 45.8 6.6 18.0% +1.2% (insignificant) 8:2 total 343.2 19.0 339.1 15.4 54.7% +1.2% (insignificant) 8:2 function 38.9 3.9 40.2 6.9 52.4% -3.2% (insignificant) 6:6 total 658.4 15.7 604.6 20.8 100.0% +8.9% 6:6 function 109.0 8.7 59.5 5.4 100.0% +83.3% 8:8 total 896.2 24.5 766.4 17.6 100.0% +16.9% 8:8 function 223.4 12.8 93.8 5.0 100.0% +138.3% 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.
