From 3a81c753a3cfdcea215268c00f98ac87a09902e1 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Mon, 31 Dec 2018 11:51:01 -0800 Subject: v3d: Fix segfault when failing to compile a program. We'll still fail at draw time, but this avoids a regression in shader-db execution once I enable TLB writes in precompiles.
