Diego Biurrun	88bd7fdc82	Drop DCTELEM typedef It does not help as an abstraction and adds dsputil dependencies. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	12 years ago
Ronald S. Bultje	ce58642ed0	x86inc: support stack mem allocation and re-alignment in PROLOGUE. Use this in VP8/H264-8bit loopfilter functions so they can be used if there is no aligned stack (e.g. MSVC 32bit or ICC 10.x). Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	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

Ronald S. Bultje	45549339bc	vp8: disable mmx functions with sse/sse2 counterparts on x86-64. x86-64 is guaranteed to have at least SSE2, therefore the MMX/MMX2 functions will never be used in practice.	13 years ago

Dave Yeo	cc73511e8e	Fix NASM include directive Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Ronald S. Bultje	b2c087871d	Move x86util.asm from libavcodec/ to libavutil/. This allows using it in swscale also.	14 years ago
Ronald S. Bultje	3a39195b1d	Move x86inc.asm to libavutil/. This allows using it in libswscale/ also.	14 years ago
Daniel Kang	d0005d347d	Modify x86util.asm to ease transitioning to 10-bit H.264 assembly. Arguments for variable size instructions are added to many macros, along with other various changes. The x86util.asm code was ported from x264. Signed-off-by: Diego Biurrun <diego@biurrun.de>	14 years ago

Mans Rullgard	2912e87a6c	Replace FFmpeg with Libav in licence headers Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Reimar Döffinger	b1c32fb5e5	Use "d" suffix for general-purpose registers used with movd. This increases compatibilty with nasm and is also more consistent, e.g. with h264_intrapred.asm and h264_chromamc.asm that already do it that way. Originally committed as revision 25042 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Ronald S. Bultje	3611c45ab7	Mark xmm registers as clobbered in simple loopfilter. Should fix the last two VP8-related fate failures on Win64. Originally committed as revision 24908 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Ronald S. Bultje	684d608bde	Fix segfaults in VP8 SIMD code on Win64 (and FATE/win64 failures). Originally committed as revision 24871 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	827d43bb9d	VP8: move zeroing of luma DC block into the WHT Lets us do the zeroing in asm instead of C. Also makes it consistent with the way the regular iDCT code does it. Originally committed as revision 24668 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Ronald S. Bultje	6341838f3c	Use word-writing instead of dword-writing (with two cached but otherwise unchanged bytes) in the horizontal simple loopfilter. This makes the filter quite a bit faster in itself (~30 cycles less on Core1), probably mostly because we don't need a complex 4x4 transpose, but only a simple byte interleave. Also allows using pextrw on SSE4, which speeds up even more (e.g. 25% faster on Core i7). Originally committed as revision 24638 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Ronald S. Bultje	ab4d031889	Use pmaddubsw for the mbedge_filter (>=ssse3), 6-10 cycles faster. Originally committed as revision 24514 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	e25dee602f	VP8: Much faster SSE2 MC 5-10% faster or more on Phenom, Athlon 64, and some others. Helps some on pre-SSSE3 Intel chips as well, but not as much. Originally committed as revision 24513 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Ronald S. Bultje	48adb7e7a4	Enable no-loop memory/register saving for ssse3/sse4 also. Originally committed as revision 24511 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Ronald S. Bultje	2a180c69ea	Save a register (or regsize of stackspace for x86-32) for the no-loop mbedge loopfilter functions, by re-using space that holds a variable that we no longer need. Originally committed as revision 24510 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Ronald S. Bultje	bcd4aa6498	Use nested ifs instead of &&, which appears to not work with %ifidn (i.e. this construct was always enabled, even for <ssse3 versions). Originally committed as revision 24509 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Ronald S. Bultje	2208053bd3	Split pextrw macro-spaghetti into several opt-specific macros, this will make future new optimizations (imagine a sse5) much easier. Also fix a bug where we used the direction (%2) rather than optimization (%1) to enable this, which means it wasn't ever actually used... Originally committed as revision 24507 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Ronald S. Bultje	6de5b7c6b8	Fix obvious bug in assignment. Somehow, the test vectors don't test this... Originally committed as revision 24489 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Ronald S. Bultje	e3f7bf774c	Fix SPLATB_REG mess. Used to be a if/elseif/elseif/elseif spaghetti, so this splits it into small optimization-specific macros which are selected for each DSP function. The advantage of this approach is that the sse4 functions now use the ssse3 codepath also without needing an explicit sse4 codepath. Originally committed as revision 24487 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	3ae079a3c8	VP8: optimize DC-only chroma case in the same way as luma. Add MMX idct_dc_add4uv function for this case. ~40% faster chroma idct. Originally committed as revision 24455 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	51c9156438	VP8 asm: cosmetics (spacing) Originally committed as revision 24453 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	8a467b2d44	VP8: 30% faster idct_mb Take shortcuts based on statistically common situations. Add 4-at-a-time idct_dc function (mmx and sse2) since rows of 4 DC-only DCT blocks are common. TODO: tie this more directly into the MB mode, since the DC-level transform is only used for non-splitmv blocks? Originally committed as revision 24452 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	c25c776708	VP8: clear DCT blocks in iDCT instead of using clear_blocks. ~0.3% faster overall. Originally committed as revision 24448 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Ronald S. Bultje	dc5eec8085	Use pextrw for SSE4 mbedge filter result writing, speedup 5-10cycles on CPUs supporting it. Originally committed as revision 24437 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Ronald S. Bultje	003243c3c2	Fix and enable horizontal >=SSE2 mbedge loopfilter. Originally committed as revision 24409 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	8731dbd890	Eliminate one instruction in VP8 dc_add_sse4 Originally committed as revision 24405 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	7dd224a42d	Various VP8 x86 deblocking speedups SSSE3 versions, improve SSE2 versions a bit. SSE2/SSSE3 mbedge h functions are currently broken, so explicitly disable them. Originally committed as revision 24403 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	b8b231b5dc	Make mmx VP8 WHT faster Avoid pextrw, since it's slow on many older CPUs. Now it doesn't require mmxext either. Originally committed as revision 24397 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Ronald S. Bultje	e9e456d850	VP8 MBedge loopfilter MMX/MMX2/SSE2 functions for both luma (width=16) and chroma (width=8). Originally committed as revision 24378 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
