From: Ilia Mirkin Date: Sun, 30 Nov 2014 00:24:35 +0000 (-0500) Subject: freedreno/a3xx: enable sampling from integer textures X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=82104c19f304a0e953172ad61d149640f0512fa0;p=mesa.git freedreno/a3xx: enable sampling from integer textures We need to produce a u32 destination type on integer sampling instructions, so keep that in a shader key set based on the currently-bound textures.
