Michael Niedermayer	ef912134f0	x86/swscale: use unsigned to build SIMD values to avoid signed overflow Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	14de55784d	sws/output: use unsigned variables where harmless overflows are expected. signed overflow is undefined in C ... Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Martin Storsjö	75c37c5ace	swscale: Provide the right alignment for external mmx asm This reverts parts of `e0c6cce447`. There is external mmx asm that requires this alignment. This fixes crashes when using swscale in builds with external mmx, without inline assembly. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Diego Biurrun	e0c6cce447	x86: Replace checks for CPU extensions and flags by convenience macros This separates code relying on inline from that relying on external assembly and fixes instances where the coalesced check was incorrect.	12 years ago

Ronald S. Bultje	b64a72e1b2	yuv2rgb: handle line widths that are not a multiple of 4. This introduces support for width%4==2 in addition to width%4==0. For odd widths, some more checks are needed, since the current code always handles two luma items in a row, thus there is a possibility of an overread by one.	13 years ago

Mans Rullgard	90540c2d5a	x86: swscale: fix fragile memory accesses To access data at multiple fixed offsets from a base address, this code uses a single "m" operand and code of the form "32%0", relying on the memory operand instantiation having no displacement, giving a final result of the form "32(%rax)". If the compiler uses a register and displacement, e.g. "64(%rax)", the end result becomes "3264(%rax)", which obviously does not work. Replacing the "m" operands with "r" operands allows safe addition of a displacement. In theory, multiple memory operands could use a shared base register with different index registers, "(%rax,%rbx)", potentially making more efficient use of registers. In the cases at hand, no such sharing is possible since the addresses involved are entirely unrelated. After this change, the code somewhat rudely accesses memory without using a corresponding memory operand, which in some cases can lead to unwanted "optimisations" of surrounding code. However, the original code also accesses memory not covered by a memory operand, so this is not adding any defect not already present. It is also hightly unlikely that any such optimisations could be performed here since the memory locations in questions are not accessed elsewhere in the same functions. This fixes crashes with suncc. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	10b83cb653	x86: swscale: remove disabled code This code has been disabled since 2003. Nobody will ever look at it again. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Reimar Döffinger	118bd609f0	Optimized unscaled yuvp9/yuvp10 -> yuvp16 conversion. About 30% faster on 32 bit Atom, 120% faster on 64 bit Phenom2. This is interesting because supporting P16 is easier in e.g. OpenGL (can misuse support for any 2-component 8 bit format), whereas supporting p9/p10 without conversion needs a texture format with at least 14 bits actual precision. The shiftonly == 0 case is not optimized since the code is more complex and the speed gain less obvious. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago
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>	13 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.	13 years ago

Pavel Koshevoy	665100c2f1	Fix destination row striding in altivec_yuv2_bgr24. Misaligned row artifacts showed up when a 624x352 frame was converted to BGR24 format. When advancing to the next row the destination linesize was added to the last output pointer position which was not linesize aligned, resulting in a distorted picture.
