* PPC: Move types_altivec.h and util_altivec.h from libavcodec to libavutilJustin Ruggles2012-06-08
| | | | | This will allow for easier implementation of Altivec functions in libraries other than libavcodec.
* ppc: dsputil: do unaligned block accesses correctlyMans Rullgard2012-05-01
| | | | | | | | | | | | To load unaligned vector data in the usual way, explicit vec_ld() should be used rather than dereferencing a pointer to a vector type. When the VSX extension is enabled, gcc may compile vector pointer dereferences using the VSX lxvw4x instruction instead of the lvx instruction typically used with Altivec/VMX. As the behaviour of these instructions with unaligned addresses differs, it is important that only lvx is used here. Signed-off-by: Mans Rullgard <mans@mansr.com>

* Adds 8-, 9- and 10-bit versions of some of the functions used by the h264 ↵Oskar Arvidsson2011-05-10
| | | | | | | | | | | | | | | | | decoder. This patch lets e.g. dsputil_init chose dsp functions with respect to the bit depth to decode. The naming scheme of bit depth dependent functions is <base name>_<bit depth>[_<prefix>] (i.e. the old clear_blocks_c is now named clear_blocks_8_c). Note: Some of the functions for high bit depth is not dependent on the bit depth, but only on the pixel size. This leaves some room for optimizing binary size. Preparatory patch for high bit depth h264 decoding support. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>

* PPC: move prototypes to headers and make some functions staticMåns Rullgård2010-03-06

* PPC: remove unnecessary alignment on local variablesMåns Rullgård2009-08-24
| | | | | | | | | Storing a single element from a vector where all elements have the same value does not require an aligned destination. Which element is stored depends on the alignment of the destination address, but since they all have the same value, the result is the same regardless of the alignment.

* Remove AltiVec vector declaration compiler compatibility macros.Diego Biurrun2008-07-24
| | | | | | | | | | The original problem was that FSF and Apple gcc used a different syntax for vector declarations, i.e. {} vs. (). Nowadays Apple gcc versions support the standard {} syntax and versions that support {} are available on all relevant Mac OS X versions. Thus the greater compatibility is no longer worth cluttering the code with macros. Originally committed as revision 14366 to svn://svn.ffmpeg.org/ffmpeg/trunk
