From 9ac5ec2f90f8b6b2c0e67039b1ae7590374be872 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Wed, 17 Apr 2019 10:09:14 -0700 Subject: [PATCH] nir: Fix deref offset calculation for structs. We were calcuating the offset for the field within the struct, and just dropping it on the floor. Fixes a regression in KHR-GLES3.shaders.struct.local.nested_struct_array_dynamic_index_fragment and a few of its friends since the scratch lowering commit.
