Diego Biurrun	ef5d41a553	x86inc: Rename "program_name" to "private_prefix" The new name is more descriptive and will allow defining a separate public prefix for externally visible library symbols. Signed-off-by: Diego Biurrun <diego@biurrun.de>	12 years ago
Xi Wang	f73f76fd20	swscale: fix NULL checking in sws_alloc_context() sws_getCachedContext() and sws_getContext() expect sws_alloc_context() to return NULL when out of memory, as follows. if (!(context = sws_alloc_context())) return NULL; This patch fixes sws_alloc_context() to return NULL in that case.

Kostya Shishkov	38fdf72580	swscale: do not forget to swap data in formats with different endianness 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.

Diego Biurrun	04581c8c77	x86: yasm: Use complete source path for macro helper %includes This is more consistent with the way we handle C #includes and it simplifies the build system.	12 years ago
Diego Biurrun	6860b4081d	x86: include x86inc.asm in x86util.asm This is necessary to allow refactoring some x86util macros with cpuflags.	12 years ago

Mans Rullgard	a805cefd8b	swscale: avoid pointless use of compound literals Some compilers (e.g. old gcc) have trouble with these. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Mans Rullgard	95cd815c36	swscale: try to use mmap only if available 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>	12 years ago

Mans Rullgard	07eb7e20af	ppc: swscale: rework yuv2planeX_altivec() 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>	12 years ago

Martin Storsjö	75c37c5ace	swscale: Provide the right alignment for external mmx asm This reverts parts of `e0c6cce447`. 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>	12 years ago

Ronald S. Bultje	b64a72e1b2	yuv2rgb: handle line widths that are not a multiple of 4. 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.	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
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
