19a0729b4c
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>

If you notice errors in the align stuff, need more alignment for some ASM code

for some CPU or need to use a function with less aligned data then send a mail
|
|
to the ffmpeg-devel mailing list, ...
|
|
|
|
!warning These alignments might not match reality, (missing attribute((align))
|
|
stuff somewhere possible).
|
|
I (Michael) did not check them, these are just the alignments which I think
|
|
could be reached easily ...
|
|
|

!future video codecs might need functions with less strict alignment
