Diego Biurrun	831a118078	Update dsputil- and SIMD-related comments to match reality more closely	11 years ago
Diego Biurrun	7c00e9d8ae	x86: ac3dsp: Remove 3dnow version of ff_ac3_extract_exponents The function requires increasing the fuzz factor for the ac3/eac3 encode tests and even so makes fate fail. It only provides a slight encoding speedup for legacy CPUs that do not support SS2. Thus its benefit is not worth the trouble it creates and fixing it would be a waste of time.	12 years ago
Diego Biurrun	4f56e773fe	x86: ac3: Fix HAVE_MMXEXT condition to only refer to external assembly CC: libav-stable@libav.org	12 years ago
Diego Biurrun	51969a652c	x86: ABS2: port to cpuflags	12 years ago
Diego Biurrun	26301caaa1	x86: mmx2 ---> mmxext in asm constructs	12 years ago
Diego Biurrun	26f01bd106	x86: PMINUB: port to cpuflags	12 years ago
Diego Biurrun	9ce02e14f0	x86: ac3dsp: port to cpuflags	12 years ago
Diego Biurrun	588fafe7f3	x86: MMX2 ---> MMXEXT in macro names	12 years ago
Diego Biurrun	04581c8c77	x86: yasm: Use complete source path for macro helper %includes This is more consistent with the way we handle C #includes and it simplifies the build system.	12 years ago
Diego Biurrun	6860b4081d	x86: include x86inc.asm in x86util.asm This is necessary to allow refactoring some x86util macros with cpuflags.	12 years ago
Diego Biurrun	17337f54c0	x86: Split inline and external assembly #ifdefs	12 years ago
Diego Biurrun	239fdf1b4a	x86: build: replace mmx2 by mmxext Refactoring mmx2/mmxext YASM code with cpuflags will force renames. So switching to a consistent naming scheme beforehand is sensible. The name "mmxext" is more official and widespread and also the name of the CPU flag, as reported e.g. by the Linux kernel.	12 years ago
Justin Ruggles	95a98ab3f0	ac3dsp: simplify x86 versions of ac3_max_msb_abs_int16 Simplifies the code by using cpuflags and a new macro. Also fixes the invalid use of the MMX2 pshufw operation in the MMX-only function.	13 years ago
Justin Ruggles	de7f22ab0c	ac3dsp: call femms/emms at the end of float_to_fixed24() for 3DNow and SSE Fixes ac3-encode and eac3-encode FATE test failures with SSE2 disabled. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Justin Ruggles	d483bb58c3	ac3dsp: do not use pshufb in ac3_extract_exponents_ssse3() We need to do unsigned saturation in order to cover the corner case when the absolute coefficient value is 16777215 (the maximum value). Fixes Bug #216	13 years ago
Ronald S. Bultje	3b15a6d742	config.asm: change %ifdef directives to %if directives. This allows combining multiple conditionals in a single statement.	13 years ago
Dave Yeo	cc73511e8e	Fix NASM include directive Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Ronald S. Bultje	b2c087871d	Move x86util.asm from libavcodec/ to libavutil/. This allows using it in swscale also.	13 years ago
Ronald S. Bultje	3a39195b1d	Move x86inc.asm to libavutil/. This allows using it in libswscale/ also.	13 years ago
Justin Ruggles	f99a5ef92e	ac3dsp: add x86-optimized versions of ac3dsp.extract_exponents().	14 years ago
Justin Ruggles	70bb747a57	ac3dsp: do not use the ff_* prefix when referencing ff_ac3_bap_bits. this should fix the windows builds Signed-off-by: Martin Storsjö <martin@martin.st>	14 years ago
Justin Ruggles	6ca23db9cc	ac3enc: modify mantissa bit counting to keep bap counts for all values of bap instead of just 0 to 4. This does all the actual bit counting as a final step.	14 years ago
Diego Biurrun	888fa31eca	Fix FSF address copy paste error in some license headers.	14 years ago
Mans Rullgard	2912e87a6c	Replace FFmpeg with Libav in licence headers Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Justin Ruggles	0f999cfddb	ac3enc: add float_to_fixed24() with x86-optimized versions to AC3DSPContext and use in scale_coefficients() for the floating-point AC-3 encoder.	14 years ago
Justin Ruggles	f1efbca5e9	ac3enc: add SIMD-optimized shifting functions for use with the fixed-point AC3 encoder.	14 years ago
Justin Ruggles	1f004fc512	ac3dsp: Change punpckhqdq to movhlps in ac3_max_msb_abs_int16(). Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Justin Ruggles	fbb6b49dab	ac3enc: Add x86-optimized function to speed up log2_tab(). AC3DSPContext.ac3_max_msb_abs_int16() finds the maximum MSB of the absolute value of each element in an array of int16_t. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Justin Ruggles	dda3f0ef48	Add x86-optimized versions of exponent_min(). Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
