* x86inc: Drop SECTION_TEXT macroHenrik Gramner2015-08-11
| | | | | | | 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>

* yadif: restore speed of the C filtering codeJames Darnley2013-05-14
| | | | | | | | | | | | | | 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>

* lavfi/gradfun: remove rounding to match C and SSE code.Clément Bœsch2013-03-28
| | | | | | There is no noticable benefit for such precision. Signed-off-by: Anton Khirnov <anton@khirnov.net>
* lavfi/gradfun: fix dithering in MMX code.Clément Bœsch2013-03-28
| | | | | | Current dithering only uses the first 4 instead of the whole 8 random values. Signed-off-by: Anton Khirnov <anton@khirnov.net>
* lavfi/gradfun: fix rounding in MMX code.Clément Bœsch2013-03-28
| | | | | | | | | | | | | | | 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 m*m*delta >> 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>

* vf_yadif: silence a warning.Anton Khirnov2013-02-06
| | | | | | | 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)'

* yadif: x86: fix build for compilers without aligned stackDaniel Kang2013-01-14
| | | | | | | 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>

|
* x86: yasm: Use complete source path for macro helper %includesDiego Biurrun2012-10-31
| | | | | This is more consistent with the way we handle C #includes and it simplifies the build system.
* x86: include x86inc.asm in x86util.asmDiego Biurrun2012-10-31
| | | | This is necessary to allow refactoring some x86util macros with cpuflags.

| | | | | 13% faster on penryn, 16% on sandybridge, 15% on bulldozer Not simd; a compiler should have generated this, but gcc didn't.

* x86: yadif: fix asm with sunccMans Rullgard2012-08-13
| | | | | | | | | | | | | | | | 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. Signed-off-by: Mans Rullgard <mans@mansr.com>
* x86: rename libavutil/x86_cpu.h to libavutil/x86/asm.hMans Rullgard2012-08-09
| | | | | | | This puts x86-specific things in the x86/ subdirectory where they belong. Signed-off-by: Mans Rullgard <mans@mansr.com>
* x86: build: replace mmx2 by mmxextDiego Biurrun2012-08-03
| | | | | | | 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.
* x86: yadif: Mark mmxext optimizations as suchDiego Biurrun2012-07-31
| | | | | The yadif mmx optimizations contain the pmaxsw and pmaxub mmxext instructions, causing sigills on CPUs that do not support mmxext.
* lavfi: place x86 inline assembly under HAVE_INLINE_ASM.Ronald S. Bultje2012-07-22
| | | | | This allows compiling this code using compilers that do not understand gcc-style inline assembly.
* x86: lavfi: fix gradfun/yadif build with mmx/sse disabledMans Rullgard2012-07-03
| | | | | | | These functions are defined conditionally so any uses need to have preprocessor guards. Signed-off-by: Mans Rullgard <mans@mansr.com>
