From 4b38c5c783e8858f362bb1ff6cf651875bd0bbc5 Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Mon, 30 Mar 2015 05:17:56 -0700 Subject: [PATCH] nir: In prog->nir, don't wrap dot products with ptn_channel(..., X). ptn_move_dest and nir_fadd already take care of replicating the last channel out, so we can just use a scalar and skip splatting it.
