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>	12 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>	12 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>	12 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>	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

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.
