From: Claudio Sacerdoti Coen Date: Tue, 11 Mar 2008 22:02:58 +0000 (+0000) Subject: Very experimental commit: the type of the source is now required in LetIns X-Git-Tag: make_still_working~5538 X-Git-Url: http://matita.cs.unibo.it/gitweb/?a=commitdiff_plain;h=cc23f034c9419186602d9250456241f2eba90d7c;p=helm.git Very experimental commit: the type of the source is now required in LetIns and Defs. This is a back-porting from the new generation kernel. TODO: a) debug some failing examples (paramodulation) b) port the code by Ferruccio c) do something for Coq files (that are now rejected) --- diff --git a/helm/software/components/acic_content/acic2content.ml b/helm/software/components/acic_content/acic2content.ml index 69a1f632d..b10464bda 100644 --- a/helm/software/components/acic_content/acic2content.ml +++ b/helm/software/components/acic_content/acic2content.ml @@ -78,7 +78,7 @@ let rec occur uri = | C.Prod (_,s,t) -> (occur uri s) or (occur uri t) | C.Cast (te,ty) -> (occur uri te) | C.Lambda (_,s,t) -> (occur uri s) or (occur uri t) (* or false ?? *) -
