Subject: st/nine: Compact ff vs constants a bit
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=567be40de9246ff30a337e8c5916dc45ea5664eb;p=mesa.git

st/nine: Compact ff vs constants a bit

There are several holes. This patch reduces
the holes a bit, which reduces the size of
the constant buffer uploaded.
