Subject: radv: spir-v allows texture size query with and without lod.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b1340fd708bb873617b8a529ac45cbc9507bd6c4;p=mesa.git

radv: spir-v allows texture size query with and without lod.

The translation to llvm was failing here due to required lod.

This fixes some new  SteamVR shaders.
