2009-03-17- gros commit sur ring et field: passage des arguments simplifiebarras

2009-03-16Cleaning/improving the use of the "in" clause (e.g. "unfold foo in H at 4"herbelin
now works correctly, "unfold foo at 4 in H at 3" now fails correctly, etc.). The terminology for clauses (though I don't find the term "clause" very intuitive after all) is mostly preserved except for "simple_clause" which becomes a light form of "clause" instead of being an atom of clause (what played the role of "simple_clause" is now called "goal_location" - better names are welcome). Main changes are in tacticals.ml and tactics.ml. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11981 85f007b7-540e-0410-9357-904b9bb8a0f7

2009-03-04Backtrack sur la mémoïsation de nf_evar.aspiwack
L'expérience prouve que ce n'est pas franchement concluant. On peut se risquer à une explication : - nf_evar, version mémoïsée n'est pas tail recursive - On retarde la substitution des hypothèses de l'evar en échange de faire moins de substitutions d'evars. Intuitivement c'est intéressant seulement si il y a plus de substitutions d'evar dupliquées que d'hypothèses dupliquées. Ce qui ne doit pas être le cas (ne serait-ce que parce que dupliquer une evar duplique aussi ses variables libres). This reverts commit 066a564021788e995eb166ad6ed6e55611d6f593. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11958 85f007b7-540e-0410-9357-904b9bb8a0f7

2009-02-19On remplace evar_map par evar_defs (seul evar_defs est désormais exporté aspiwack
par Evd). Ça s'accompagne de quelques autres modifications de l'interface (certaines fonctions étaient des doublons, ou des conversions entre evar_map et evar_defs). J'ai modifié un peu la structure de evd.ml aussi, pour éviter des fonctions redéfinies deux fois (i.e. définies trois fois !), j'ai introduit des sous-modules pour les différentes couches. Il y a à l'heure actuelle une pénalité en performance assez sévère (due principalement à la nouvelle mouture de Evd.merge, si mon diagnostique est correct). Mais fera l'objet de plusieurs optimisations dans les commits à venir. Un peu plus ennuyeux, la test-suite du mode déclaratif ne passe plus. Un appel de Decl_proof_instr.mark_as_done visiblement, je suis pour l'instant incapable de comprendre ce qui cause cette erreur. J'espère qu'on pourra le déterminer rapidement. Ce commit est le tout premier commit dans le trunk en rapport avec les évolution futures de la machine de preuve, en vue en particulier d'obtenir un "vrai refine". git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11939 85f007b7-540e-0410-9357-904b9bb8a0f7

2009-01-23Petit nettoyage faisant suite au commit #11847 .aspiwack
Quelques modifications autour (géographiquement) de Util.list_split_at Util.list_split_at devient Util.list_split_when (dénomination inventée arbitrairement par moi-même, mais qui ne devrait pas déranger grand monde vu qu'il semble n'y avoir que deux occurences de cette fonction). Pour laisser la place à la fonction suivante : Introduction de Util.list_split_at: qui sépare la liste à une position donnée (alors que la nouvellement nommé list_split_when sépare à la première occurence "vrai" d'un prédicat). Ajout de quelques commentaires dans util.ml (pas le mli) sur ces deux fonctions. Suppression de Impargs.list_split_at (appel à Util). Suppression de Subtac_pretyping.list_split_at (qui était du code mort de toute façon). Suppression Util.list_split_by qui n'est utilisé nulle part et est une réimplémentation de List.partition (qui est probablement meilleure, en particulier tail-recursive) git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11851 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-01-21Fix bug #2004 due to bad handling of evars in the unification for msozeau
the setoid_rewrite variant called by rewrite (bug traced by Hugo). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11822 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-01-18Various little fixes:msozeau
- allow a new line after a (** printing *) directive in coqdoc so as not to output spurious new lines. - never directly unify the lemma with an evar in setoid_rewrite (they act as opaque constants). - Fix a useless dependency introduced by tauto which splits a record in SetoidList. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11799 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-01-18Getting rid of the previous implementation of setoid_rewrite which wasmsozeau
unplugged a long time ago. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11798 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-01-12Fix a bunch of bugs related to setoid_rewrite, unification and evars:msozeau
- Really unify with types of metas when they contain metas _or_ evars (why not always?) (fixes bug #2027). - Better handling of evars in rewrite lemmas when using setoid_rewrite through rewrite (reported by Ralf Hinze). - Use retyping with metas when possible (check?) and improve an obscure error message in retyping. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11776 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-01-11- Deactivation of dynamic loading on Mac OS 10.5 (see bug #2024).herbelin
- Added dependency of mltop.ml4 into config/Makefile (see bug #2023). - Fixed bug #1963 (dependent inversion building a universe-ill-formed conversion problem). - Incidentally, moved "Large non-propositional inductive ..." error message to standard himsg.ml error displayer. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11774 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-01-04Fixed bugs #2001 (search_guard was overwriting the guard index givenherbelin
by user) and #2017 (unification pattern test too crude leading to regression wrt to 8.1). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11743 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-01-03Fixed two problems:herbelin
- Function descend_in_conjunctions was now too weak, use match_with_record. - Added documentation of new notation for destruct with equation. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11742 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-01-02- Temptative change to notations like "as [|n H]_eqn" or "as [|n H]_eqn:H",herbelin
and, with a now generic intropattern "[]", also "as []_eqn", "as []_eqn:H" for "destruct" with equality keeping. - Fixed an accuracy loss in error location. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11732 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-01-01Switched to "standardized" names for the properties of eq andherbelin
identity. Add notations for compatibility and support for understanding these notations in the ml files. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11729 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-01-01- Fixed bug #2021 (uncaught exception with injection/discriminate whenherbelin
the inductive status of a projectable position comes from a dependency). - Improved doc of the stdlib chapter (see bug #2018), and fixed tex bugs introduced in r11725. - Applied wish #2012 (max_dec transparent). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11728 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-12-31Moved parts of Sign to Term. Unified some names (e.g. decomp_n_prod ->herbelin
splay_prod_n, lam_it -> it_mkLambda, splay_lambda -> splay_lam). Added shortcuts for "fst (decompose_prod t)" and co. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11727 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-12-30- Fixed bugs and compatibilities issues in herbelin
match_conjunction/match_disjunction/array_for_all_i - Finally activate fine-tuned unfolding of iff in tauto: it breaks at only one place in the user contribs (FSetAVL_dep.v). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11726 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-12-29- Added support for subterm matching in SearchAbout.herbelin
- Backtrack on precise unfolding of "iff" in "tauto": it has effects on the naming of hypotheses (especially when doing "case H" with H of type "{x|P<->Q}" since not unfolding will eventually introduce a name "i" while unfolding will eventually introduce a name "a" (deep sigh). - Miscellaneous (error when a plugin is missing, doc hnf, standardization of names manipulating type constr_pattern, ...). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11725 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-12-28- Another bug in get_sort_family_of (sort-polymorphism of constants andherbelin
inductive types was not taken into account). - Virtually extended tauto to - support arbitrary-length disjunctions and conjunctions, - support arbitrary complex forms of disjunctions and conjunctions when in the contravariant of an implicative hypothesis, - stick with the purely propositional fragment and not apply reflexivity. This is virtual in the sense that it is not activated since it breaks compatibility with the existing tauto. - Modified the notion of conjunction and unit type used in hipattern in a way that is closer to the intuitive meaning (forbid dependencies between parameters in conjunction; forbid indices in unit types). - Investigated how far "iff" could be turned into a direct inductive definition; modified tauto.ml4 so that it works with the current and the alternative definition. - Fixed a bug in the error message from lookup_eliminator. - Other minor changes. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11721 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-12-26- Extracted from the tactic "now" an experimental tactic "easy" for smallherbelin
automation. - Permitted to use evars in the intermediate steps of "apply in" (as expected in the test file apply.v). - Back on the systematic use of eq_rect (r11697) for implementing rewriting (some proofs, especially lemma DistOoVv in Lyon/RulerCompassGeometry/C14_Angle_Droit.v and tactic compute_vcg in Sophia-Antipolis/Semantics/example2.v are explicitly refering to the name of the lemmas used for rewriting). - Fixed at the same time a bug in get_sort_of (predicativity of Set was not taken into account). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11717 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-12-26- Optimized "auto decomp" which had a (presumably) exponential inherbelin
the number of conjunctions to split. - A few cleaning and uniformisation in auto.ml. - Removal of v62 hints already in core. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11715 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-12-18- Fixed cutrewrite bug #2021 introduced in commit 11662 (as a sideherbelin
effect, old cut_replacing was betaiota-normalizing, new cut_replacing, from commit 11662, does not; turn betaiota-normalisation into a purer and simpler whd_beta of the abstracted rewriting predicate to the rewritten term). - Made "induction in" more flexible when induction is on a goal variable (accept occurrences -- even if theoretically unnecessary -- so as e.g. not to expand occurrences that would otherwise trigger reductions - see example in Peano.mult_succ_r). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11697 85f007b7-540e-0410-9357-904b9bb8a0f7

2008-12-09About "apply in":herbelin
- Added "simple apply in" (cf wish 1917) + conversion and descent under conjunction + contraction of useless beta-redex in "apply in" + support for open terms. - Did not solve the "problem" that "apply in" generates a let-in which is type-checked using a kernel conversion in the opposite side of what the proof indicated (hence leading to a potential unexpected penalty at Qed time). - When applyng a sequence of lemmas, it would have been nice to allow temporary evars as intermediate steps but this was too long to implement. Smoother API in tactics.mli for assert_by/assert_as/pose_proof. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11662 85f007b7-540e-0410-9357-904b9bb8a0f7

2008-10-26Fixes and refinements regarding occurrence selection:herbelin
- make the modifiers "value of" and "type of" for "set" working (it was not!), - clear unselected hypotheses in the "in" clause of "induction/destruct" when the destructed term is a variable (experimental), - support for generalization of hypotheses in the induction hypotheses using the "in" clause of "induction" (e.g. "induction n in m, H" will generalize over m -- would it be better to have an explicit "over"/"generalizing" clause ?). Added clause "as" to "apply in". git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11509 85f007b7-540e-0410-9357-904b9bb8a0f7
