From e961ace331ec961dcec0e2525d7b9142d04b5154 Mon Sep 17 00:00:00 2001 From: msozeau Date: Sun, 27 Apr 2008 11:16:15 +0000 Subject: - Fix bug in unification not taking into account the right meta substitution. Makes unification succeed a bit more often, hence auto works better in some cases. - Backtrack the changes of auto using Hint Unfold to do more delta and add a new tactic "new auto" which does that, for compatibility. The first fix may have a big impact on the contribs, whereas the second should make them compile again... we'll see. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10855 85f007b7-540e-0410-9357-904b9bb8a0f7 --- theories/Sets/Powerset_Classical_facts.v | 1 + 1 file changed, 1 insertion(+) (limited to 'theories/Sets') diff --git a/theories/Sets/Powerset_Classical_facts.v b/theories/Sets/Powerset_Classical_facts.v index ac3664054..8116045b6 100644 --- a/theories/Sets/Powerset_Classical_facts.v +++ b/theories/Sets/Powerset_Classical_facts.v @@ -101,6 +101,7 @@ Section Sets_as_an_algebra. intros X x H'; red in |- *. intros x0 H'0; try assumption. elim (classic (x = x0)); intro K; auto with sets. + elim K; auto with sets.
