* Merge subinstances branch by me and Tom Prince.Gravatar msozeau2011-11-17
| | | | | | | | | | | | | | This adds two experimental features to the typeclass implementation: - Path cuts: a way to specify through regular expressions on instance names search pathes that should be avoided (e.g. [proper_flip proper_flip]). Regular expression matching is implemented through naïve derivatives. - Forward hints for subclasses: e.g. [Equivalence -> Reflexive] is no longer applied backwards, but introducing a specific [Equivalence] in the environment register a [Reflexive] hint as well. Currently not backwards-compatible, the next patch will allow to specify direction of subclasses hints. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14671 85f007b7-540e-0410-9357-904b9bb8a0f7

* Refined second_order_matching so that a constraint on whichGravatar herbelin2011-11-08
| | | | | | | | | | | | | | | | occurrences to abstract can be given. This allows to force "destruct" to necessarily abstract over all occurrences of its main argument (only the sub-arguments that occur in the inductive type of the main argument have their occurrences constrained by typing). This incidentally avoids "rewrite" succeeding in rewriting only a part of the occurrences it has to rewrite. This repairs the failure of RecursiveDefinition which failed after pattern unification fix from r14642). Full support for selecting occurrence of main argument still to be done though. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14648 85f007b7-540e-0410-9357-904b9bb8a0f7
* optimization: memoization for is_open_canonical_projectionGravatar gareuselesinge2011-11-08
| | | | | | | | | | | Assume a pile of constants on the left, and a stuck canonical projection on the right. We are going to unfold the left constants step by step, and at every step, we are going to recheck that the very same projection on the right is stuck. The new check for stuck canonical projections is more expensive, we thus memoize it for the whole sequence of delta steps on the left. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14646 85f007b7-540e-0410-9357-904b9bb8a0f7
* Improved check is_open_canonical_projectionGravatar gareuselesinge2011-11-08
| | | | | | | | | | | | | | The check looks for 1 canonical projection applied to a meta/evar. This fails to deal with telescopes that generate unification problems containing something like "(pi_1 (pi_2 ?))" that is indeed a "stuck" canonical projection but not of the form recognized by the previous implementation. The same holds when pi_2 is a general function not producing a constructor. This patch checks if the argument of the canonical projection weak head reduces to a constructor calling whd_betadeltaiota. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14645 85f007b7-540e-0410-9357-904b9bb8a0f7
* Allow "|_=>_" in "match" in patterns, no more forced enumeration of constructorsGravatar letouzey2011-11-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For instance, consider this inductive type: Inductive Ind := A | B | C | D. For detecting "match" on this type, one was forced earlier to write code in Ltac using "match goal" and/or "context [...]" and long patterns such as: match _ with A => _ | B => _ | C => _ | D => _ end After this patch, this pattern can be shortened in many alternative ways: match _ with A => _ | _ => _ end match _ with B => _ | _ => _ end match _ in Ind with _ => _ end Indeed, if we want to detect a "match" of a given type, we can either leave at least one branch where a constructor is explicit, or use a "in" annotation. Now, we can also detect any "match" regardless of its type: match _ with _ => _ end Note : this will even detect "match" over empty inductive types. Compatibility should be preserved, since "match _ with end" will continue to correspond only to empty inductive types. Internally, the constr_pattern PCase has changed quite a lot, a few elements are now grouped into a case_info_pattern record, while branches are now lists of given sub-patterns. NB: writing "match" with missing last branches in a constr pattern was actually tolerated by Pattern.pattern_of_glob_constr earlier, since the number of constructor per inductive is unknown there. And this was triggering an uncaught exception in a array_fold_left_2 in Matching later. Oups. At least this patch fixes this issue... Btw: the code in Pattern.pattern_of_glob_constr was quadratic in the number of branch in a match pattern. I doubt this was really a problem, but having now linear code instead cannot harm ;-) git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14644 85f007b7-540e-0410-9357-904b9bb8a0f7

* Fixing incorrect change to pattern-unification over Meta's introducedGravatar herbelin2011-11-06
| | | | | | | | | | | | | | | in r14199 (June 2011). Meta's implicitly depend on the context they are defined in and this has to be taken into account for checking if occurrences are distinct (in particular, no Var's are allowed as arguments of a pattern-unifiable Meta). The example expected to be accepted thanks to r14199 is not a pattern-unification problem (it has more than one solution) and was anyway already accepted (strange). Compared to before r14199, aliases expansion and restriction of pattern unification check to variables occurring in the right-hand side are however now taken into account. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14642 85f007b7-540e-0410-9357-904b9bb8a0f7
