* Temporary fixes in unification:Gravatar msozeau2009-05-24
| | | | | | | | | | | | | | - Solve meta type equations in the order they appeared during unification: it's sensible because we do an [hnf_constr] on these types, introducing a bit of delta even when it's not allowed by the flags, and some code relies on it. A definite solution would involve an nf variant of hnf_constr or allowing delta-reduction of closed terms when unifying types. - Do a bit of betaiota reduction on types in [check_types] while we haven't got a sort-variable aware [is_trans_fconv] test. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12140 85f007b7-540e-0410-9357-904b9bb8a0f7

* A try at using sort variables during unification. Instead of refreshingGravatar msozeau2009-05-23
| | | | | | | | | | | | | universes as usual, we add the new universes to the sort constraints and do unification modulo those ([constr_unify_with_sorts]): this allows to instanciate Type i with Prop for example and keep track of it. The sort constraints are thrown away at the end of unification for the moment, but we can detect inconsistencies during unification. Make unification more symmetric as well w.r.t. substitution of defined metas. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12137 85f007b7-540e-0410-9357-904b9bb8a0f7
* Many fixes in unification:Gravatar msozeau2009-05-20
| | | | | | | | | | | | | | | | | - Restore failure when types don't unify in [unify_types] (undoing r12075) but try to be more clever about cumulativity using the meta's [instance_status] information. - Fix second-order abstraction when K is not allowed to ensure that we don't unify twice with the same subterm in [w_unify_to_subterm_list]. A more elaborate solution would be give the list to [w_unify_to_subterm] so that it keeps going when it finds an already-found instantiation. - Two "obvious" errors fixed: taking the wrong instance status when unifying with a meta on the right and forgoting type equations in [w_merge]. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12136 85f007b7-540e-0410-9357-904b9bb8a0f7

* Minor unification changes:Gravatar msozeau2009-05-18
| | | | | | | | | | | | | - Primitive setup for firing typeclass resolution on-demand: add a flag to control resolution of remaining evars (e.g. typeclasses) during unification. - Prevent canonical projection resolution when no delta is allowed during unification (fixes incompatibility found in ssreflect). - Correctly check types when the head is an evar _or_ a meta in w_unify.
