From 7c47db359e193f21be796df3a7b5d037dd42b28f Mon Sep 17 00:00:00 2001 From: Samuel Pitoiset Date: Sat, 9 Apr 2016 17:08:56 +0200 Subject: [PATCH] nv50/ir: add OP_BUFQ for buffers query TGSI RESQ allows both images and buffers but we have to make a distinction between these two type of resources in our lowering pass. Introducing OP_BUFQ which is a fake operand will allow to implement OP_SUQ for surfaces.
