Lynne	605e330310	x86/opusdsp: implement FMA3 accelerated postfilter and deemphasis 58893 decicycles in deemphasis_c, 130548 runs, 524 skips 9475 decicycles in deemphasis_fma3, 130686 runs, 386 skips -> 6.21x speedup 24866 decicycles in postfilter_c, 65386 runs, 150 skips 5268 decicycles in postfilter_fma3, 65505 runs, 31 skips -> 4.72x speedup Total decoder speedup: ~14% Deemphasis SIMD based on the following unrolling: const float c1 = CELT_EMPH_COEFF, c2 = c1c1, c3 = c2c1, c4 = c3c1; float state = coeff; for (int i = 0; i < len; i += 4) { y[0] = x[0] + c1state; y[1] = x[1] + c2state + c1x[0]; y[2] = x[2] + c3state + c1x[1] + c2x[0]; y[3] = x[3] + c4state + c1x[2] + c2x[1] + c3*x[0]; state = y[3]; y += 4; x += 4; }	6 years ago

Mikulas Patocka	fbdd78fa3e	avcodec/fft: fix INTERL macro on 3dnow The commit `b7c16a3f2c` ("x86: fft: Port to cpuflags") breaks the opus decoder in ffmpeg when compiling for 3dnow. The output is audible, but there's a lot of noise. The reason for the breakage is that the commit unintentionally changed the INTERL macro so that it is empty when compiling for 3dnow.

Michael Niedermayer	58cf31cee7	avcodec/x86/mpegvideodsp: Fix signedness bug in need_emu Fixes: out of array read Fixes: 3516/attachment-311488.dat Found-by: Insu Yun, Georgia Tech. Tested-by: wuninsu@gmail.com Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	7 years ago
Thomas Köppe	43171a2a73	Fix missing used attribute for inline assembly variables Variables used in inline assembly need to be marked with attribute((used)). Static constants already were, via the define of DECLARE_ASM_CONST. But DECLARE_ALIGNED does not add this attribute, and some of the variables defined with it are const only used in inline assembly, and therefore appeared dead. This change adds a macro DECLARE_ASM_ALIGNED that marks variables as used. This change makes FFMPEG work with Clang's ThinLTO. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	7 years ago
