Subject: i965/fs: Perform CSE on sends-from-GRF rather than textures.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=1d97212007ccaea3e98ef5485faeea130776522a;p=mesa.git

i965/fs: Perform CSE on sends-from-GRF rather than textures.

Should potentially allow a few more cases, while avoiding doing CSE on
texture operations on Gen <= 6 with the MRF.
