2012-11-25Fixed bug #2930: folded let-in's were hiding a violation to the occurherbelin
check condition in pattern-unification, resulting in the instantiation of evars by terms depending on themselves, henceforth leading eventually to a stack overflow. Occur-check in the arguments of evars was also missing. [Also fixed what looked like a typo in the env passed to project_evar_on_evar on line 1611.] git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15996 85f007b7-540e-0410-9357-904b9bb8a0f7

2012-11-08Monomorphized a lot of equalities over OCaml integers, thanks toppedrot
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

2012-11-03Reversed roles of undefined/defined evars in Evd, thus saving preciousppedrot
time when requesting only undefined evars (which is actually most often the case, as in Goal.advance). Hopefully this should not disrupt anything. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15952 85f007b7-540e-0410-9357-904b9bb8a0f7
2012-10-29Removed many calls to OCaml generic equality. This was done byppedrot
writing our own comparison functions, and enforcing monomorphization in many places. This should be more efficient, btw. Still a work in progress. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15932 85f007b7-540e-0410-9357-904b9bb8a0f7
2012-10-26Change Hint Resolve, Immediate to take a global reference as argumentmsozeau
instead of a general constr: this is the most common case and does not loose generality (one can simply define constrs before Hint Resolving them). Benefits: - Natural semantics for typeclasses, not class resolution needed at Hint Resolve time, meaning less trouble for users as well. - Ability to [Hint Remove] any hint so declared. - Simplifies the implementation as well. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15930 85f007b7-540e-0410-9357-904b9bb8a0f7

2012-09-14Moving Utils.list_* to a proper CList module, which includes stdlibppedrot
List module. That way, an "open Util" in the header permits using any function of CList in the List namespace (and in particular, this permits optimized reimplementations of the List functions, as, for example, tail-rec implementations. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15801 85f007b7-540e-0410-9357-904b9bb8a0f7
2012-09-14This patch removes unused "open" (automatically generated fromregisgia
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
2012-09-14The new ocaml compiler (4.00) has a lot of very cool warnings,regisgia
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
