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.	2016-09-29 14:48:04 +02:00
Diego Biurrun	2ec9fa5ec6	idct: Change type of array stride parameters to ptrdiff_t ... ptrdiff_t is the correct type for array strides and similar.	2016-09-29 14:48:03 +02:00
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.	2014-06-03 14:23:03 +02:00
