You are right, this conditional is not needed. I'm going to remove it
for the second version of the series.

This is a mistake. I'm going to remove it.

This if isn't needed.  If you want the assertion, an "assert not
f.is_normalized" would be ok, but I don't see the need given the continues
above.

Why are we doing UINT_TO_FLOAT here?  If these are for non-normalied
functions, shouldn't we just be clampping the floating-point value to the
maximum range for the integer?

[Mesa-dev] [PATCH 13/20] mesa: Add _mesa_pack_uint_rgba_row() format conversion function

2014-11-18 Thread Iago Toral Quiroga
From: Samuel Iglesias Gonsalvez 

We will use this later on to handle uint conversion scenarios in a master
convert function.
