* Fix bug #2056 (discharge bug).Gravatar msozeau2009-03-28
| | | | git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12029 85f007b7-540e-0410-9357-904b9bb8a0f7
* Backtrack sur la mémoïsation de nf_evar.Gravatar aspiwack2009-03-04
| | | | | | | | | | | | | | | | 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

* DISCLAIMERGravatar puech2009-01-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ========== This big patch is commited here with a HUGE experimental tag on it. It is probably not a finished job. The aim of committing it now, as agreed with Hugo, is to get some feedback from potential users to identify more clearly the directions the implementation could take. So please feel free to mail me any remarks, bug reports or advices at <puech@cs.unibo.it>. Here are the changes induced by it : For the user ============ * Search tools have been reimplemented to be faster and more general. Affected are [SearchPattern], [SearchRewrite] and [Search] (not [SearchAbout] yet). Changes are: - All of them accept general constructions, and previous syntactical limitations are abolished. In particular, one can for example [SearchPattern (nat -> Prop)], which will find [isSucc], but also [le], [gt] etc. - Patterns are typed. This means that you cannot search mistyped expressions anymore. I'm not sure if it's a good or a bad thing though (especially regarding coercions)... * New tool to automatically infer (some) Record/Typeclasses instances. Usage : [Record/Class *Infer* X := ...] flags a record/class as subject to instance search. There is also an option to activate/deactivate the search [Set/Unset Autoinstance]. It works by finding combinations of definitions (actually all kinds of objects) which forms a record instance, possibly parameterized. It is activated at two moments: - A complete search is done when defining a new record, to find all possible instances that could have been formed with past definitions. Example: Require Import List. Record Infer Monoid A (op:A->A->A) e := { assoc : forall x y z, op x (op y z) = op (op x y) z; idl : forall x, x = op x e ; idr : forall x, x = op e x }. new instance Monoid_autoinstance_1 : (Monoid nat plus 0) [...] - At each new declaration (Definition, Axiom, Inductive), a search is made to find instances involving the new object. Example: Parameter app_nil_beg : forall A (l:list A), l = nil ++ l. new instance Build_Monoid_autoinstance_12 : (forall H : Type, Monoid (list H) app nil) := (fun H : Type => Build_Monoid (list H) app nil ass_app (app_nil_beg H) (app_nil_end H)) For the developper ================== * New yet-to-be-named datastructure in [lib/dnet.ml]. Should do efficient one-to-many or many-to-one non-linear first-order filtering, faster than traditional methods like discrimination nets (so yes, the name of the file should probably be changed). * Comes with its application to Coq's terms [pretyping/term_dnet.ml]. Terms are represented so that you can search for patterns under products as fast as you would do not under products, and facilities are provided to express other kind of searches (head of application, under equality, whatever you need that can be expressed as a pattern) * A global repository of all objects defined and imported is maintained [toplevel/libtypes.ml], with all search facilities described before. * A certain kind of proof search in [toplevel/autoinstance.ml]. For the moment it is specialized on finding instances, but it should be generalizable and reusable (more on this in a few months :-). The bad news ============ * Compile time should increase by 0 to 15% (depending on the size of the Requires done). This could be optimized greatly by not performing substitutions on modules which are not functors I think. There may also be some inefficiency sources left in my code though... * Vo's also gain a little bit of weight (20%). That's inevitable if I wanted to store the big datastructure of objects, but could also be optimized some more. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11794 85f007b7-540e-0410-9357-904b9bb8a0f7

* Factorisation des opérations sur le type option de Util dans un module Gravatar aspiwack2007-12-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | lib/option.ml(i) . J'en profite pour rajouter des primitives de lifting des fonctions (à un ou deux arguments tous ou partie de type option). Il reste quelques opérations dans Util à propos desquelles je ne suis pas trop sûr, ou simplement que j'ai oublié, mais qui attendront demain car il est tard (comme some_in qui devrait devenir Option.make je suppose) . Elles s'expriment souvent facilement en fonction des autres, par exemple "option_compare x y" est égal à "Option.lift2 compare x y" . Le option_cons devrait faire son chemin dans le module parce qu'il est assez primitif et qu'il n'y a pas de fonction "cons" dans OCaml. J'en ai profité aussi pour remplacer les trop nombreux "failwith" par des erreurs locales au module, donc plus robustes. J'ai trouvé aussi une fonction qui était définie deux fois, et une définie dans un module particulier. Mon seul bémol (mais facile à traiter) c'est la proximité entre le nom de module Option et l'ancien Options. J'ai pas de meilleure idée de nom à l'heure qu'il est, ni pour l'un, ni pour l'autre. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10346 85f007b7-540e-0410-9357-904b9bb8a0f7

* HUGE COMMITGravatar sacerdot2005-01-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. when applying a functor F(X) := B to a module M, the obtained module is no longer B{X.t := M.t for all t}, but B{X.t := b where b is the body of t in M}. In principle it is now easy to fine tune the behaviour to choose whether b or M.t must be used. This change implies modifications both inside and outside the kernel. 2. for each object in the library it is now necessary to define the behaviour w.r.t. the substitution {X.t := b}. Notice that in many many cases the pre-existing behaviour w.r.t. the substitution {X.t := M.t} was broken (in the sense that it used to break several invariants). This commit fixes the behaviours for most of the objects, excluded a) coercions: a future commit should allow any term to be declared as a coercion; moreover the invariant that just a coercion path exists between two classes will be broken by the instantiation. b) global references when used as arguments of a few tactics/commands In all the other cases the behaviour implemented is the one that looks to me as the one expected by the user (if possible): [ terminology: not expanded (X.t := M.t) vs expanded (X.t := b) ] a) argument scopes: not expanded b) SYNTAXCONSTANT: expanded c) implicit arguments: not expanded d) coercions: expansion to be done (for now not expanded) e) concrete syntax tree for patterns: expanded f) concrete syntax tree for raw terms: expanded g) evaluable references (used by unfold, delta expansion, etc.): not expanded h) auto's hints: expanded when possible (i.e. when the expansion of the head of the pattern is rigid) i) realizers (for program extraction): nothing is done since the actual code does not look for the realizer of definitions with a body; however this solution is fragile. l) syntax and notation: expanded m) structures and canonical structures: an invariant says that no parameter can happear in them ==> the substitution always yelds the original term n) stuff related to V7 syntax: since this part of the code is doomed to disappear, I have made no effort to fix a reasonable semantics; not expanded is the default one applied o) RefArgTypes: to be understood. For now a warning is issued whether expanded != not expanded, and the not expanded solution is chosen. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@6555 85f007b7-540e-0410-9357-904b9bb8a0f7

* IMPORTANT COMMIT: constant is now an ADT (it used to be equal to kernel_name).Gravatar sacerdot2004-11-16
| | | | | | | | | | | | | | | MOVITATION: in a forthcoming commit the application of a substitution to a constant will return a constr and not a constant. The application of a substitution to a kernel_name will return a kernel_name. Thus "constant" should be use as a kernel name for references that can be delta-expanded. KNOWN PROBLEMS: the only problem faced is in pretyping/recordops.ml (the code that implements "Canonical Structure"s). The ADT is violated once in this ocaml module. My feeling is that the implementation of "Canonical Structure"s should be rewritten to avoid this situation. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@6303 85f007b7-540e-0410-9357-904b9bb8a0f7
