Ronald S. Bultje	70d418c7e6	Revert "PPC64: Add versions of functions in libswscale/input.c optimized for POWER8 VSX SIMD." This reverts commit `1df908f33f`. The expected performance improvements are essentially non-existent.	9 years ago
Dan Parrot	1df908f33f	PPC64: Add versions of functions in libswscale/input.c optimized for POWER8 VSX SIMD. This patch addresses Trac ticket #5570. The optimized functions are in file libswscale/ppc/input_vsx.c. Each optimized function name is a concatenation of the corresponding name in libswscale/input.c with suffix _vsx.
