From 1dec62ed43fef82b1cafbcc1fc3d63cacd90cad9 Mon Sep 17 00:00:00 2001 From: Nick Lewycky Date: Wed, 26 Dec 2012 22:00:35 +0000 Subject: [PATCH] Remove mid-optimizer warning. This situation should be handled differently, such as by a compiler warning, a check in clang -fsanitizer=undefined, being optimized to unreachable, or a combination of the above.
