From 3d66ba971e984a1c58eda6a938a37f58ba6f8134 Mon Sep 17 00:00:00 2001 From: Rob Clark Date: Thu, 26 May 2016 10:22:33 -0400 Subject: [PATCH] tgsi: fix out of bounds access Not sure why coverity calls this an out-of-bounds read vs out-of-bounds write. CID 1358920 (#1 of 1): Out-of-bounds read (OVERRUN)9. overrun-local: Overrunning array r of 3 16-byte elements at element index 3 (byte offset 48) using index chan (which evaluates to 3).
