Diego Biurrun	e4cbf7529b	Give all anonymously typedeffed structs in headers a name Anonymous structs cannot be forward declared and have no benefit.	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
Diego Biurrun	b9141aa346	swscale: Remove two bogus asserts	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
Diego Biurrun	e0c6cce447	x86: Replace checks for CPU extensions and flags by convenience macros This separates code relying on inline from that relying on external assembly and fixes instances where the coalesced check was incorrect.	12 years ago
Diego Biurrun	1169f0d0af	x86: more specific checks for availability of required assembly capabilities	12 years ago
Martin Storsjö	e6153f173a	avopt: Store defaults for AV_OPT_TYPE_INT in the i64 union member Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago

Diego Biurrun	a886b279a0	x86: cosmetics: Comment some #endifs for better readability	13 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.	13 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>	13 years ago
Mans Rullgard	10b83cb653	x86: swscale: remove disabled code This code has been disabled since 2003. Nobody will ever look at it again. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 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>	13 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.	13 years ago
