Subject: i965/fs: Allow source mods on gen7+ math.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=9156d0cba1090c4bcc3a6c0c7b2ad8921a295be4;p=mesa.git

i965/fs: Allow source mods on gen7+ math.

This gen6 restriction was removed in gen7 as the mathbox merge to act
more like a normal instruction was finished in the hardware.
