I've been on holidays last week, as far I can read in:
Matt Turner is working on a new version of the vec4 register coalescing.
This makes me wonder if it makes sense to consider now the patches I am
sending, because first, the code is going to change soon, and second, it
could be that Matt is already tackling the saturation errors in the new
register coalesce version.
