From: Samuel Pitoiset Date: Wed, 17 May 2017 08:51:59 +0000 (+0200) Subject: tgsi: store the sampler view type directly in the instruction X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=5cb2eee5573b69311da95454be1431e536212fbb;p=mesa.git tgsi: store the sampler view type directly in the instruction RadeonSI needs to do a special lowering for Gather4 with integer formats, but with bindless samplers we just can't access the index. Instead, store the return type in the instruction like the target.
