Michael Niedermayer	920dd84bf1	sws/x86: remove 8bit rgb2yuv coefficient case for rgb24toyv12 special converter This simplifies the code and improves quality at the expense of a slight slowdown of a rarely used function (no fate test uses it).

Michael Niedermayer	a37fd7f957	sws: Update rgb24toyv12_c() to user supplied rgb2yuv tables As the function arguments change, we also change the function name to ensure that anyone using this (non public) function doesnt end with hard to debug crashes. The new name also has a proper prefix. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 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>	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
