* 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

| | | | | | | | | | | All the purely monadic code has been moved to a new module Monads, where, I'm afraid to confess, I got to use a number of proof transformers to modularise the definition of tactics. It is still not easy to understand (why would it with backtracking support?) but at least it's more robust, cleaner, and more extensible. Plus there is now a Proofview.tclORELSE which will be used to interprete the Ltac tactical (t1 || t2). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15596 85f007b7-540e-0410-9357-904b9bb8a0f7
