2008-06-21Various improvements in handling of evars in general and typingmsozeau
constraints in Program: - normalize types and defs of local fixpoints before checking the guardness condition to avoid having to give type annotations, e.g: << Definition fold (A B : Set) (f : B -> A -> B) : B -> tree A -> B := fix aux acc t := match t with | Leaf x => f acc x | Node l => fold_left aux l acc end. >> - add new inh_coerce_to_prod to allow coercion of the typing constraint to a product before trying to split it. It's a noop in standard mode, and forgets subsets in Program. Allows to typecheck: << (λ x, x) : { f : nat -> nat | ... } >>. - Better handling of the "abstract" typing constraints in Program. - Correctly normalize w.r.t. evars. the tycon given by users in Program. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11156 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-06-17Cleanup in subtac_cases, preparing to use improvements on return predicatemsozeau
inference. Little improvement un subtac_obligations: do not retry to solve all obligations when finishing to solve one obligation nobody depends on. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11133 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-02-08Backport code from command.ml to subtac_command.ml for defininingmsozeau
recursive definitions. Now program accepts cofixpoints and uses the new way infer structurally decreasing arguments. Also, checks for correct recursive calls before giving the definition to the obligations machine (solves part 1 of bug #1784). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10529 85f007b7-540e-0410-9357-904b9bb8a0f7

2006-05-29The "clean integration of subtac" patch.msozeau
Adds a new kind of casts (CastCoerce) for coercing an object to its base type (e.g. inductive). The new cast_type type subsumes usual casts ConvCasts. Much of the patch is just adding ConvCasts where needed. The Pretyping module has been adapted to this change, although it doesn't change anything yet, but this construct could have a use with current coercions also. Pretyping is also cleaned from the "Use type constraints under lambdas" patch which is not yet ready for wide use. It has been transferred to a copy of the Pretyping Functor in subtac_pretyping_F.ml. Subtac is now working as well as I demonstrated at TYPES. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@8875 85f007b7-540e-0410-9357-904b9bb8a0f7
