* Extraction: Richer patterns in matchs as proposed by P.N. TollitteGravatar letouzey2011-11-28
| | | | | | | | | | | | | | | | | The MLcase has notably changed: - No more case_info in it, but only a type annotation - No more "one branch for one constructor", but rather a sequence of patterns. Earlier "full" pattern correspond to pattern Pusual. Patterns Pwild and Prel allow to encode optimized matchs without hacks as earlier. Other pattern situations aren't used (yet) by extraction, but only by P.N Tollitte's code. A MLtuple constructor has been introduced. It isn't used by the extraction for the moment, but only but P.N. Tollitte's code. Many pretty-print functions in ocaml.ml and other have been reorganized git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14734 85f007b7-540e-0410-9357-904b9bb8a0f7

* New Arguments vernacularGravatar gareuselesinge2011-11-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new vernacular "Arguments" attaches to constants the extra-logical piece of information regarding implicit arguments, notation scopes and the behaviour of the simpl tactic. The About vernacular is extended to print the new extra logical data for simpl. Examples: Arguments foo {A B}%type f [T] x. (* declares A B and T as implicit arguments, A B maximally inserted. declares type_scope on A and B *) Arguments foo {A%type b%nat} p%myscope q. (* declares A and b as maximally inserted implicit arguments. declares type_scope on A, nat_scope on b and the scope delimited by myscope on p *) Arguments foo (A B)%type c d. (* declares A and b in type_scope, but not as implicit arguments. *) Arguments foo A B c. (* leaves implicit arguments and scopes declared for foo untouched *) Arguments foo A B c : clear implicits (* equivalente too Implicit Arguments foo [] *) Arguments foo A B c : clear scopes (* equivalente too Arguments Scope foo [_ _ _] *) Arguments foo A B c : clear scopes, clear implicits Arguments foo A B c : clear implicits, clear scopes Arguments foo A B c : clear scopes and implicits Arguments foo A B c : clear implicits and scopes (* equivalente too Arguments Scope foo [_ _ _]. Implcit Arguments foo [] *) Arguments foo A B c : default implicits. (* equivalent to Implicit Arguments foo. *) Arguments foo {A B} x , A [B] x. (* equivalent to Implicit Arguments foo [[A] [B]] [B]. *) Arguments foo a !b c !d. (* foo is unfolded by simpl if b and d evaluate to a constructor *) Arguments foo a b c / d. (* foo is unfolded by simpl if applied to 3 arguments *) Arguments foo a !b c / d. (* foo is unfolded by simpl if applied to 3 arguments and if b evaluates to a constructor *) git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14717 85f007b7-540e-0410-9357-904b9bb8a0f7
* Configurable simpl tacticGravatar gareuselesinge2011-11-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The problem that this patch tries to solve is that sometimes the unfolding behaviour of simpl is too aggressive, frequently exposing match constructs. Moreover one may want some constants to never be unfolded by simpl (like in the Math-Comp library where the nosimpl hack is pervasive). Finally, one may want some constants to be volatile, always unfolded by simple when applied to enough arguments, even if they do not hide a fixpoint or a match. A new vernacular command to be indroduced in a following patch attaches to constants an extra-logical piece of information. It declares wich arguments must be checked to evaluate to a constructor before performing the unfolding of the constant (in the same spirit simpl considers as such the recursive argument of an inner fixpoint). Examples: Arguments minus !x !y. (* x and y must evaluate to a constructor for simpl to unfold minus *) (S x - y) --- simpl ---> (S x - y) (S x - S y) --- simpl ---> (x - y) Definition fcomp A B C (f : B -> C) (g : A -> B) x := f (g x). Arguments fcomp A B C f g x /. Infix "\o" := fcomp (at level 50, left associativity) : nat_scope. (* fcomp hides no fix, but simpl will unfold if applied to 6 arguments *) (fun x => (f \o g) x) = f \o g --- simpl ---> (fun x => f (g x)) = f \o g Arguments minus x y : simpl never. (* simpl will never unfold minus *) (S x - S y) --- simpl ---> (S x - S y) Definition nid (x : nat) := x. Arguments nid / x. (* nid is volatile, unfolded by simpl when applied to 0 or more arguments *) nid --- simpl ---> (fun x => x) Arguments minus x y : simpl nomatch. (* triggers for minus the "new" simpl heuristic I discussed with Hugo: if reducing the fix would leave a match in "head" position then don't unfold a suggestion for a better name (for "nomatch") would be appreciated *) (0 - y) --- simpl ---> 0 (S x - y) --- simpl ---> (S x - y) (S x - S y) --- simpl ---> (x - y) (minus 0) --- simpl ---> (minus 0) (* This last test does not work as one may expect, i.e. (minus 0) --- simpl ---> (fun _ => 0) The point is that simpl is implemented as "strong whd_simpl" and after unfolding minus you have (fun m => match 0 => 0 | S n' => ...n' - m'... end) that is already in whd and exposes a match, that of course "strong" would reduce away but at that stage we don't know, and reducing by hand under the lambda is against whd reduction. So further discussion on that idea is needed. *) git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14716 85f007b7-540e-0410-9357-904b9bb8a0f7

* Changed the way to detect if an "as" patterns is expanded or not. TheGravatar herbelin2011-11-21
| | | | | | | | | | | | | | | | | | main criterion is to look at whether the alias to the term to match is dependent in the return predicate or not. Since the exact return predicate is often found late, the detection is done after the subproblem is fully compiled, when a maximum amount of (local) information on typing is known. Eventually, we should go to a model where all possible partial expansions of an alias are usable at typing time. Indeed the current heuristic (like the previous one) is not fully safe since it might decide not to expand an alias in a branch whose type does not depend of the alias but the typing of the branch internally needs the expansion (as e.g. in "fun (H:forall n, n=0->Prop) n => match n with 0 as x => H x eq_refl | _ => True end"). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14701 85f007b7-540e-0410-9357-904b9bb8a0f7
