libavcodec/lagarith.c:671:16: warning: '#' flag used with ‘%u’ gnu_printf format [-Wformat]

There is no point in populating NuvContext with another DSPContext.

Also split static and dynamic initialization bits to avoid running the

This gets rid of aliasing completely unrelated structs to Picture.

This is in line with how the top-level libavcodec Makefile is structured.

This avoids recalculating the value over and over again.

This allows for a more natural macro usage.

It is not supported by all compilers on FATE. Fixes "some test were
skipped" errors.

This fixes fate-float_dsp-test on RVCT 4.0.

Only enable it for CPUs that support it.
This restores the behavior prior to 7a650caf.

The specification uses lower case most of the time.

Print the UL in code format and in the short format used by the
specification.
