* commit '896a5bff64264f4d01ed98eacc97a67260c1e17e': arm: check if AS supports .dn Conflicts: configure libavcodec/arm/vc1dsp_init_neon.c Merged-by: Michael Niedermayer <michaelni@gmx.at>
2014-06-03arm: check if AS supports .dnJanne Grunau
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.

This should reduce the frequency with which the offsets need to be updated.
2014-04-25vc-1: Add platform-specific start code search routine to VC1DSPContext.Ben Avison
Initialise VC1DSPContext for parser as well as for decoder. Note, the VC-1 code doesn't actually use the function pointer yet. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

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>
