* Monomorphization (pretyping)Gravatar ppedrot2012-11-22
| | | | git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15994 85f007b7-540e-0410-9357-904b9bb8a0f7
* Monomorphized a lot of equalities over OCaml integers, thanks toGravatar ppedrot2012-11-08
| | | | | | | | | | | | | | | | | the new Int module. Only the most obvious were removed, so there are a lot more in the wild. This may sound heavyweight, but it has two advantages: 1. Monomorphization is explicit, hence we do not miss particular optimizations of equality when doing it carelessly with the generic equality. 2. When we have removed all the generic equalities on integers, we will be able to write something like "let (=) = ()" to retrieve all its other uses (mostly faulty) spread throughout the code, statically. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15957 85f007b7-540e-0410-9357-904b9bb8a0f7

* The new ocaml compiler (4.00) has a lot of very cool warnings,Gravatar regisgia2012-09-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | especially about unused definitions, unused opens and unused rec flags. The following patch uses information gathered using these warnings to clean Coq source tree. In this patch, I focused on warnings whose fix are very unlikely to introduce bugs. (a) "unused rec flags". They cannot change the semantics of the program but only allow the inliner to do a better job. (b) "unused type definitions". I only removed type definitions that were given to functors that do not require them. Some type definitions were used as documentation to obtain better error messages, but were not ascribed to any definition. I superficially mentioned them in one arbitrary chosen definition to remove the warning. This is unaesthetic but I did not find a better way. (c) "unused for loop index". The following idiom of imperative programming is used at several places: "for i = 1 to n do that_side_effect () done". I replaced "i" with "_i" to remove the warning... but, there is a combinator named "Util.repeat" that would only cost us a function call while improving readibility. Should'nt we use it? git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15797 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

* Make simpl use the proper constant when folding (mutual) fixpointsGravatar letouzey2011-01-27
| | | | | | | | | | | | | | | | | | | | | | | Before this commit, when simpl was finding the constant name for folding some (mutual) fixpoint, this was done via some repr_con followed by make_con. Problem: this doesn't preserve the canonical part of a Names.constant. For instance the following script was buggish: Module M. Fixpoint foo n := match n with O => O | S n => bar n end with bar n := match n with O => O | S n => foo n end. End M. Module N. Include M. (* foo, bar have here "user name" N but "canonical name" M *) Eval simpl in (fun x => bar (S x)). (* Anomaly: uncaught exception Failure "Cannot print a global reference". *) (* since simpl has produce a different bar with both user and canonical N *) TODO : check all other uses of make_con in the rest of the sources... git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13803 85f007b7-540e-0410-9357-904b9bb8a0f7

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.
