2009-05-28Ajout d'un printer modulaire pour les constr. C'est-à-dire une fonctionaspiwack
qui permet de changer la façon dont on imprime certains sous-termes sans avoir à réécrire entièrement un printer de constr. Dans le même esprit que les commits sur le parser et le lexer, je cherche à donner une flexibilité aux plugins pour changer l'aspect de Coq pour le plier à d'autres conventions. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12151 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-05-27Fix implicit args code so that declarations are added for allmsozeau
definitions and variables (may increase the vo's size a bit), which in turn fixes discharging with manual implicit args only.

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

2009-05-18Minor unification changes:msozeau
- 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. Move [isEvar_or_Meta] to kernel/term.ml, it's used in two places now. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12131 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-05-17- Allowing multiple calls to tactic fix with automatic generation ofherbelin
function name (instead of failure). - Making descent through conjunctions in apply work on recursive tuples such as Acc. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12129 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-05-16(Tentative to) add Canonical Structure resolution to the regularmsozeau
unification algorithm. Uses the same code to recognize projections (check_conv_record) and the same unification steps on the solution as evar_conv. This required to fold the sigma through unify_* along with the meta and evar substitutions as this can grow during unification. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12128 85f007b7-540e-0410-9357-904b9bb8a0f7

2009-05-10- Addition of "Hint Resolve ->" and "Hint Resolve <-" continued: itherbelin
