From 8cd1b76b7d9e5190b74653c4f40672c2024839a1 Mon Sep 17 00:00:00 2001 From: Neil Roberts Date: Sun, 2 Dec 2018 18:15:52 +0100 Subject: freedreno/ir3: Fix loading half-float immediate vectors Previously the code to load from a constant instruction was always using the u32 pointer. If the constant is actually a 16-bit source this would end up with the wrong values because the pointer would be offset by the wrong size. This fixes it to use the u16 pointer.
