+=== 0001-Use-Value_Range-when-applying-inferred-ranges.patch ===
+From 69a233610f6b27cd4283561569d8ce0f35044dc4 Mon Sep 17 00:00:00 2001
+From: Andrew MacLeod <amacleod@redhat.com>
+Date: Wed, 19 Oct 2022 09:21:22 -0400
+Subject: [PATCH] Use Value_Range when applying inferred ranges.
+
+Applying an inferred range is using int_range_ma as the
+temporary rather than the general purpose Value_Range.  This causes it
+to trap if we have a non-integral inferred range.
+
+	* gimple-range-cache.cc (ranger_cache::range_from_dom): Use
+	  Value_Range not int_range_max.
