Subject: i965/fs: Add missing register allocation for 3rd sources.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=a1bfafc5a96012c14db9b0d28223ab54feae131c;p=mesa.git

i965/fs: Add missing register allocation for 3rd sources.

Our only instruction with a 3rd source so far was linterp, and that
value was never register-allocated.
