FFmpeg/libavcodec/x86/hpeldsp_init.c
Andreas Rheinhardt 947d51f32a avcodec/x86/hpeldsp_vp3: Merge into hpeldsp 
Once upon a time, 413abbe164
added versions of some put_no_rnd_pixels functions for use
in VP3 and Theora (with an explicit check so that they are
only used for VP3 and Theora). When this was moved to hpeldsp
(from dsputil) in 3ced55d51c,
the check was replaced by a check for the bitexact flag
(and a CONFIG_VP3_DECODER compile-time check), so that
these functions were now used for other codecs as well.

Later commit 1dfc3cf89d
split off the "VP3-specific bits into a separate file",
yet these bits were not really VP3-specific bits at all
any more. (The error was repeated in commit
0a39c9ac0bfd7345fe676b4e2707d9cec3cbb553.) This commit
has not been reverted, because this would make future
changes from Libav (from where it originated) harder,
yet Libav is no more, so this commit effectively reverts
1dfc3cf89d.
