Martin Storsjö	d7320ca3ed	arm: Avoid using .dn register aliases clang now (in the upcoming 5.0 version) is capable of building our arm assembly without relying on gas-preprocessor, although clang/LLVM doesn't support .dn register aliases. The VC1 MC assembly was only built and used if the chosen assembler supported the .dn directives though. This was supported as long as gas-preprocessor was used. This means that VC1 decoding got a speed regression on clang 5.0, unless the user manually chose using gas-preprocessor again. By avoiding using the .dn register aliases, we can build the VC1 MC assembly with the latest clang version. Support for the .dn/.qn directives in clang/LLVM isn't actively planned, see https://bugs.llvm.org/show_bug.cgi?id=18199. This partially reverts `896a5bff64`.

Diego Biurrun	e4a94d8b36	h264chroma: Change type of stride parameters to ptrdiff_t This avoids SIMD-optimized functions having to sign-extend their stride argument manually to be able to do pointer arithmetic.	8 years ago

Janne Grunau	896a5bff64	arm: check if AS supports .dn Move the GNU as check before the arch specific asm checks since the .dn check requires gas compatible assembler. Disable the VC-1 motion compensation NEON asm which is the only part using that directive. The integrated assembler in the upcoming clang 3.5 does not support .dn/.qn without plans to change that. Too much effort to implement it while it is rarely used. http://llvm.org/bugs/show_bug.cgi?id=18199.	11 years ago
Michael Niedermayer	af89a685c4	avcodec/arm/vc1dsp_init_neon: fix code so it compiles and passes fate-vc1 The original patch seems to be missing a 16x16 function though Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Christophe Gisquet	319235c67c	vc1dsp: introduce cases for 8x8 and 16x16 This allows further unrolling the DSP implementation where possible. x86 and ARM DSP modified by simply moving the multiple calls from vc1dec to the DSP code. Decoding improvements should only occurs because of the compiler actually able to unroll more. Decoding time: ~8.80s -> 8.64s (ie around 2%) Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
