+From f2c03ce3babe51eecbf03735f726c4028a162857 Mon Sep 17 00:00:00 2001
+From: Julian Seward <jseward@acm.org>
+Date: Wed, 28 Nov 2018 14:15:06 +0100
+Subject: [PATCH] Bug 401112 - LLVM 5.0 generates comparison against partially
+ initialized data.
+
+This generalises the existing spec rules for W of 32 bits:
+
+ W <u 0---(N-1)---0 1 0---0 or
+
+(that is, B/NB after SUBL, where dep2 has the above form), to also cover
+
+ W <=u 0---(N-1)---0 0 1---1
+
+(that is, BE/NBE after SUBL, where dept2 has the specified form).
+
+Patch from Nicolas B. Pierron (nicolas.b.pierron@nbp.name).
