2009-04-21Rename [Morphism] into [Proper] and [respect] into [proper] to complymsozeau
with standard math nomenclature. Also clean up in rewrite.ml4. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12097 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-04-17- Fix handling of clauses in setoid_rewrite to rewrite under bindersmsozeau
correctly. - Fix the new autorewrite to implement the (unstated) invariant that the last declared rules are applied first, which makes a difference for non-confluent rewrite rules. Some scripts in CoLoR rely on that. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12092 85f007b7-540e-0410-9357-904b9bb8a0f7

2009-04-14Rewrite autorewrite to use a dnet indexed by the left-hand sides (ormsozeau
rhs) of rewrite lemmas for efficient retrieval of matching lemmas. Autorewrite's implementation is still unchanged but the dnet can be used through the [hints] strategy of the new generalized rewrite. Now lemmas are checked to actually be rewriting lemmas at declaration time hence the change in DoubleSqrt where some unapplicable constants were declared as lemmas. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12087 85f007b7-540e-0410-9357-904b9bb8a0f7

2009-04-13Rewrite of setoid_rewrite to modularize it based on proof-producingmsozeau
strategies (à la ELAN). Now setoid_rewrite is just one strategy and autorewrite is a more elaborate one. Any kind of traversals can be defined, strategies can be composed etc... in ML. An incomplete (no fix) language extension for specifying them in Ltac is there too. On a typical autorewrite-with-setoids usage, proof production time is divided by 2 and proof size by 10. Fix some admitted proofs and buggy patterns in Classes.Morphisms as well. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12081 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-04-10Fix premature optimisation in dependent induction: even variable args needmsozeau
to be generalized as they may appear in other arguments or their types. Try to keep the original names around as well, using the ones found in the goal. This only requires that interning a pattern [forall x, _] properly declares [x] as a metavariable, binding instances are already part of the substitutions computed by [extended_matches]. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12079 85f007b7-540e-0410-9357-904b9bb8a0f7

2009-04-08Some dead code removal + cleanupsletouzey
This commit concerns about the first half of the useless code mentionned by Oug for coqtop (without plugins). For the moment, Oug is used in a mode where any elements mentionned in a .mli is considered to be precious. This already allows to detect and remove about 600 lines, and more is still to come. Among the interesting points, the type Entries.specification_entry and its constructors SPExxx were never used. Large parts of cases.ml (and hence subtac_cases.ml) were also useless. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12069 85f007b7-540e-0410-9357-904b9bb8a0f7

2009-03-22Backport from v8.2 branch of 11986 (interpretation of quantifiedherbelin
hypotheses in induction, unbalanced parenthesis in ltac call stack printer) and 12003 (late update of CREDITS) + update of magic numbers (using a somehow arbitrary value between the 8.2 magic numbers and the possibly forthcoming 8.3 magic numbers). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12007 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-03-22Compromise wrt introduction-names compatibility issue after additionherbelin
of new support for dependent "destruct" over terms in dependent types (r11944): dependencies in evars are not considered to be a cause of dependent "destruct". This solves one of the incompatibilities revealed in contribs. The other one comes from a "destruct_call" on a truly dependent goal. Fortunately, dependent destruct makes that destruct_call now works better and the corresponding script can be shortened (FSetAVL_prog). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12006 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-03-20Many changes in the Makefile infrastructure + a beginning of ocamlbuildletouzey
* generalize the use of .mllib to build all cma, not only in plugins/ * the .mllib in plugins/ now mention Bruno's new _mod.ml files * lots of .cmo enumerations in Makefile.common are removed, since they are now in .mllib * the list of .cmo/.cmi can be retreive via a shell script line, see for instance rule install-library * Tolink.core_objs and Tolink.ide now contains ocaml _modules_, not _files_ * a -I option to coqdep_boot allows to control piority of includes (some files with the same names in kernel and checker ...) This is quite a lot of changes, you know who to blame / report to if something breaks. ... and last but not least I've started playing with ocamlbuild. The myocamlbuild.ml is far from complete now, but it already allows to build coqtop.{opt,byte} here. See comments at the top of myocamlbuild.ml, and don't hesitate to contribute, either for completing or simplifying it ! git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12002 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-03-20Fixes to make Ynot compile with the trunk:msozeau
- Choose one of the possible instances of an evar when considering remaining unification constraints: otherwise we just do nothing and some evars remain uninstantiated. - Normalise the goal w.r.t. evars before subst, to avoid a double vision problem: the substituted variable appears only in an instance of an evar and when we try the rewrite it has been substituted making the dependency disappear. - Hack to correcly handle let-in annotations which are internalized as casts: they're really typing constraints. Shouldn't we just change the AST to have the type at rawconstr let-in nodes? git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11998 85f007b7-540e-0410-9357-904b9bb8a0f7

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

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).

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

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
