2009-06-18Use more consistent resolution parameters in Program and regular typingmsozeau
and add an optional fail_evar flag to control resolution better in interpretation functions. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12197 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-06-18Fix "unsatisfiable constraints" error messages to include all themsozeau
necessary information. Fix implementation of [split_evars] and use splitting more wisely as it has a big performance impact. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12196 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-06-18Try typeclass resolution in coercion if no solution can be found to amsozeau
conversion problem. TODO: The right fix is to use constraints and backtracking search when solving them. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12195 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-06-17Fallback on not using [fix_proto] if the right imports aren't there, the msozeau
tactics that use it won't be in scope either. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12193 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-06-16Reimplementation of leibniz rewrite to control the instantiation of themsozeau
rewriting lemma more precisely. This should make rewrite properly fail when existentials are around instead of giving an identical goal up to new evars. Also a first step towards adding occurences to the leibniz rewrite. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12192 85f007b7-540e-0410-9357-904b9bb8a0f7

2009-06-11Use a lazy value for the message in FailError, so that it won't bemsozeau
unnecessarily computed when the user won't see it (avoids the costly nf_evar_defs in typeclass errors). Add hook support for mutual definitions in Program.

2009-06-11When typing a non-dependent arrow, do not put the (anonymous) variablemsozeau
in the context to avoid it being abstracted over in potential evars occuring in the codomain, which can prevent unifications. Add [intro] to the typeclasses eauto and fix [make_resolve_hyp] to properly normalize types w.r.t. evars before searching for a class in an hypothesis. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12182 85f007b7-540e-0410-9357-904b9bb8a0f7

2009-06-07- Added two new introduction patterns with the following temptative syntaxes:herbelin
- "*" implements Arthur Charguéraud's "introv" - "**" works as "; intros" (see also "*" in ssreflect). - Simplifying the proof of Z_eq_dec, as suggested by Frédéric Blanqui. - Shy attempt to seize the opportunity to clean Zarith_dec but Coq's library is really going anarchically (see a summary of the various formulations of total order, dichotomy of order and decidability of equality and in stdlib-project.tex in branch V8revised-theories). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12171 85f007b7-540e-0410-9357-904b9bb8a0f7

2009-05-24Temporary fixes in unification:msozeau
- 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
2009-05-24Moved and completed the history of Coq versions from theherbelin
revised-theories branch. The V5.10 period at Lyon is still unclear. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12138 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-05-23A try at using sort variables during unification. Instead of refreshingmsozeau
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
2009-05-20Many fixes in unification:msozeau
- 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
2009-05-20- Fixing declarative mode in presence of high use of Change_evars nodesherbelin
(bug 2092 and decl_mode.v in test suite). - Added a debugging printer for pftreestate. - Fixing American spelling in RefMan-decl.tex. - Optimizing application of tactic validation by removing consistency test in descend. - Fixing printing ambiguity for Hint Rewrite ->/<- in extratactics.ml4. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12134 85f007b7-540e-0410-9357-904b9bb8a0f7
