* swscale: do not forget to swap data in formats with different endiannessKostya Shishkov2012-10-31
| | | | | | | | Otherwise during scaling it will try to interpret input in the wrong way and that leads to the test results disagreeing on different platforms and with different optimizations. Signed-off-by: Diego Biurrun <diego@biurrun.de>

* x86: yasm: Use complete source path for macro helper %includesDiego Biurrun2012-10-31
| | | | | This is more consistent with the way we handle C #includes and it simplifies the build system.
* x86: include x86inc.asm in x86util.asmDiego Biurrun2012-10-31
| | | | This is necessary to allow refactoring some x86util macros with cpuflags.

* swscale: support gray to 9bit and 10bit formatsLuca Barbato2012-10-30
| | | | With the input of Kostya and Ronald.
* swscale: avoid pointless use of compound literalsMans Rullgard2012-10-23
| | | | | | Some compilers (e.g. old gcc) have trouble with these. Signed-off-by: Mans Rullgard <mans@mansr.com>
* swscale: try to use mmap only if availableMans Rullgard2012-10-15
| | | | | | | | | | | | Some systems, e.g. Minix, have sys/mman.h defining MAP_ANONYMOUS without providing (working) mmap and friends. The mmx filter generation code checks only for MAP_ANONYMOUS, not for availability of mmap itself which leads to build errors on aforementioned systems. This changes the conditional compilation to use mmap only if all the required functions are available. Signed-off-by: Mans Rullgard <mans@mansr.com>

* Give all anonymously typedeffed structs in headers a nameDiego Biurrun2012-10-06
| | | | Anonymous structs cannot be forward declared and have no benefit.
* ppc: swscale: rework yuv2planeX_altivec()Mans Rullgard2012-10-05
| | | | | | | | | 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>
* swscale: Remove two bogus assertsDiego Biurrun2012-09-13

* swscale: Provide the right alignment for external mmx asmMartin Storsjö2012-09-09
| | | | | | | | | | This reverts parts of e0c6cce4472. 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>
* x86: Replace checks for CPU extensions and flags by convenience macrosDiego Biurrun2012-09-08
| | | | | This separates code relying on inline from that relying on external assembly and fixes instances where the coalesced check was incorrect.
* x86: more specific checks for availability of required assembly capabilitiesDiego Biurrun2012-09-07

* yuv2rgb: handle line widths that are not a multiple of 4.Ronald S. Bultje2012-08-28
| | | | | | | 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.

* 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.
