From: Jason Ekstrand Date: Sat, 16 Apr 2016 20:25:24 +0000 (-0700) Subject: i965/surface_state: Use libisl functions for image format lowering X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=541e6c05000b87cee02d5f8e1adc7973c2a2deea;p=mesa.git i965/surface_state: Use libisl functions for image format lowering This lets us delete some redundant code and keep all of the image_load_store format lowering logic in one place: libisl.
