From 4cc4e14d6e34752c613d6701e5378708b219b242 Mon Sep 17 00:00:00 2001 From: msozeau Date: Sun, 6 Dec 2009 00:20:53 +0000 Subject: Fix anomaly when using typeclass resolution with filtered hyps in evars. Make setoid_rewrite-through-rewrite's selection of occurences more robust: do not try unification with reduction if not needed. This changes a few scripts that were using reduction in a far from obvious way and could break more. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12562 85f007b7-540e-0410-9357-904b9bb8a0f7 --- theories/Numbers/Cyclic/Int31/Cyclic31.v | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'theories/Numbers/Cyclic') diff --git a/theories/Numbers/Cyclic/Int31/Cyclic31.v b/theories/Numbers/Cyclic/Int31/Cyclic31.v index 7d795cf50..5d6ed9abe 100644 --- a/theories/Numbers/Cyclic/Int31/Cyclic31.v +++ b/theories/Numbers/Cyclic/Int31/Cyclic31.v @@ -2029,7 +2029,7 @@ Section Int31_Spec.
