* ppc: Restrict some Altivec implementations to Big EndianLuca Barbato2015-05-31
| | | | | In Little Endian the vec_ld/vec_st operations work as expected only for byte-vectors.

* ppc: reduce overreads when loading 8 pixels in altivec dsp functionsJanne Grunau2014-02-14
| | | | | | | | | | | Altivec can only load naturally aligned vectors. To handle possibly unaligned data a second vector is loaded from an offset of the original location and the data is recovered through a vector permutation. Overreads are minimal if the offset for second load points to the last element of data. This is 7 for loading eight 8-bit pixels and overreads are reduced from 16 bytes to 8 bytes if the pixels are 64-bit aligned. For unaligned pixels the overread is reduced from 23 bytes to 15 bytes in the worst case.
