From 71572ebb32e5a460e5039fb27903f60b3b89e037 Mon Sep 17 00:00:00 2001 From: Iago Toral Quiroga Date: Tue, 4 Aug 2020 11:18:46 +0200 Subject: [PATCH] nir/lower_tex: skip lower_tex_packing for the texture samples query MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Similar to other skips for texture queries that don't actually sample the texture and which results are not packed. We can't use nir_tex_instr_is_query() here to skip the lowering for all queries since that causes regressions in Piglit. Apparently, we do want to lower some of the query results. In particularly, the LOD query.
