Diego Biurrun	39e208f4d4	build: Generalize yasm/nasm-related variable names None of them are specific to the YASM assembler.	8 years ago
Diego Biurrun	6be7944ee2	x86: Add missing colons after assembly labels This fixes many warnings of the sort warning: label alone on a line without a colon might be in error	8 years ago
Diego Biurrun	dc40a70c57	Drop unnecessary libavutil/x86/asm.h #includes	9 years ago
Henrik Gramner	ab43beefab	x86inc: Drop SECTION_TEXT macro The .text section is already 16-byte aligned by default on all supported platforms so `SECTION_TEXT` isn't any different from `SECTION .text`. Signed-off-by: Anton Khirnov <anton@khirnov.net>	9 years ago

James Darnley	b0ef0ae776	yadif: restore speed of the C filtering code Always use the special filter for the first and last 3 columns (only). Changes made in `64ed397` slowed the filter to just under 3/4 of what it was. This commit restores the speed while maintaining identical output. For reference, on my Athlon64: 1733222 decicycles in old 2358563 decicycles in new 1727558 decicycles in this Signed-off-by: Anton Khirnov <anton@khirnov.net>	12 years ago

Diego Biurrun	c1ad70c3cb	x86: Move some conditional code around to avoid unused variable warnings	12 years ago
Clément Bœsch	1ae44c87c9	lavfi/gradfun: remove rounding to match C and SSE code. There is no noticable benefit for such precision. Signed-off-by: Anton Khirnov <anton@khirnov.net>	12 years ago
Clément Bœsch	38a2f88d39	lavfi/gradfun: fix dithering in MMX code. Current dithering only uses the first 4 instead of the whole 8 random values. Signed-off-by: Anton Khirnov <anton@khirnov.net>	12 years ago
Clément Bœsch	2d66fc543b	lavfi/gradfun: fix rounding in MMX code. Current code divides before increasing precision. Also reduce upper bound for strength from 255 to 64. This will prevent an overflow in the SSSE3 and MMX filter_line code: delta is expressed as an u16 being shifted by 2 to the left. If it overflows, having a strength not above 64 will make sure that m is set to 0 (making the mmdelta >> 14 expression void). A value above 64 should not make any sense unless gradfun is used as a blur filter. Signed-off-by: Anton Khirnov <anton@khirnov.net>	12 years ago
Loren Merritt	5b3c1aecb2	hqdn3d: Fix out of array read in LOWPASS CC:libav-stable@libav.org Signed-off-by: Anton Khirnov <anton@khirnov.net>	12 years ago
Anton Khirnov	64ed397635	vf_yadif: fix out-of line reads Some changes in the border pixels, visually indistinguishable.	12 years ago
Anton Khirnov	99162f8d46	vf_yadif: silence a warning. clang says: libavfilter/vf_yadif.c:192:28: warning: incompatible pointer types assigning to 'void ()(uint8_t , uint8_t , uint8_t , uint8_t , int, int, int, int, int)' from 'void (uint16_t , uint16_t , uint16_t , uint16_t *, int, int, int, int, int)'	12 years ago

Daniel Kang	67360ccd51	yadif: x86: fix build for compilers without aligned stack Manually load registers to avoid using 8 registers on x86_32 with compilers that do not align the stack (e.g. MSVC). Signed-off-by: Diego Biurrun <diego@biurrun.de>	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	f6c38c5f4e	avfilter: call x86 init functions under if (ARCH_X86), not if (HAVE_MMX)	12 years ago

Loren Merritt	7a1944b907	vf_hqdn3d: x86 asm 13% faster on penryn, 16% on sandybridge, 15% on bulldozer Not simd; a compiler should have generated this, but gcc didn't.	12 years ago
Martin Storsjö	1d9c2dc89a	Don't include common.h from avutil.h Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Mans Rullgard	480178a295	x86: yadif: fix asm with suncc Under some circumstances, suncc will use a single register for the address of all memory operands, inserting lea instructions loading the correct address prior to each memory operand being used in the code. In the yadif code, the branch in the asm block bypasses such an lea instruction, causing an incorrect address to be used in the following load. This patch replaces the tmpX arrays with a single array and uses a register operand to hold its address. Although this prevents using offsets from the stack pointer to access these locations, the code still builds as 32-bit PIC even with old compilers.

Mans Rullgard	c318626ce2	x86: rename libavutil/x86_cpu.h to libavutil/x86/asm.h This puts x86-specific things in the x86/ subdirectory where they belong. Signed-off-by: Mans Rullgard <mans@mansr.com>	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
Diego Biurrun	d1505db067	x86: yadif: Mark mmxext optimizations as such The yadif mmx optimizations contain the pmaxsw and pmaxub mmxext instructions, causing sigills on CPUs that do not support mmxext.	12 years ago
Ronald S. Bultje	3124886554	lavfi: place x86 inline assembly under HAVE_INLINE_ASM. This allows compiling this code using compilers that do not understand gcc-style inline assembly.	13 years ago
Mans Rullgard	fb93e61e2b	x86: lavfi: fix gradfun/yadif build with mmx/sse disabled These functions are defined conditionally so any uses need to have preprocessor guards. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
