From a87c0c4f0f47f5dc4b4d7050b15713a9f7a52757 Mon Sep 17 00:00:00 2001 From: Michael Brown Date: Fri, 20 Jul 2012 18:32:58 +0100 Subject: [PATCH] [isa] Avoid spurious compiler warning on gcc 4.7 gcc 4.7 produces a spurious warning about an array subscript being out of bounds. Use a pointer dereference instead of an array lookup to inhibit this spurious warning.
