* Fixed a bug in the algorithm trying to elaborate a "match" return predicate.Gravatar herbelin2012-12-17
| | | | | | | | | | | | | This occurred in a second choice strategy which is anyway probably not used in general, but the bug showed up in error messages since these messages reports on the second choice when the first choice has failed because of user-side typing error. Anyway, having two strategies for building a return predicate will probably eventually disappear with the increase of the strength of unification. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16078 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

* This patch removes unused "open" (automatically generated fromGravatar regisgia2012-09-14
| | | | | | | | | | compiler warnings). I was afraid that such a brutal refactoring breaks some obscure invariant about linking order and side-effects but the standard library still compiles. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15800 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

* Introducing a notion of evar candidates to be used when an evar isGravatar herbelin2011-12-16
| | | | | | | | | | | | known in advance to be instantiable by only a finite number of terms. When an evar with candidates remain unsolved after unification, the first candidate is taken as a heuristic. This is used in particular to reduce the number of pending conversion problems when trying to infer the return clause of a pattern-matching problem. As an example, this repairs test 2615.v. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14797 85f007b7-540e-0410-9357-904b9bb8a0f7
