* 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>

* x86: rename libavutil/x86_cpu.h to libavutil/x86/asm.hMans Rullgard2012-08-09

* 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.

* Revert two swscale commits.Ronald S. Bultje2012-02-19
| | | | | | | | | | | Revert "swscale: update context offsets after removal of AlpMmxFilter." (commit a95e3fa90b4190381b65d180eec5a4027075e2da) and Revert "swscale: Remove some write-only variables related to alpha handling." (commit 9d03cb9fc5ddf914920ab0dbe13f19a34c754966). They broke alpha handling - it's the evil inline asm that still uses that variable, so it's not truely write-only.
* swscale: make access to filter data conditional on filter type.Ronald S. Bultje2012-02-17
