| | | | | | | | | | | | | | | | | | This gets rid of the variable-length scratch buffer by filtering 16 pixels at a time and writing directly to the destination. The extra loads this requires to load the source values are compensated by not doing a round-trip to memory before shifting. Signed-off-by: Mans Rullgard <mans@mansr.com>

| * x86: swscale: fix fragile memory accessesMans Rullgard2012-08-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* | Optimized unscaled yuvp9/yuvp10 -> yuvp16 conversion.Reimar Döffinger2012-08-12
| | | | | | | | | | | | | | | | | | | | | | | | 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>
