2013-03-12A version of Univ.check_eq with no anomaly for Evd.set_eq_sortletouzey

2013-03-12Term.dest* functions now raise specific DestKO exn instead of Invalid_argumentletouzey
**Warning** the ml code of plugins may have to be adapted after this. Concerning coq itself, I've done the adaptations, let's hope I've forgotten none. In practice, the number of changes are relatively low, and the code is quite cleaner this way. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16271 85f007b7-540e-0410-9357-904b9bb8a0f7

2013-02-21A slightly more efficient test of well-typedness of restriction ofherbelin
evars (though this might be slighty more costly). This incidentally solves Appel's part of bug #2830 even though a conceptual problem around the interaction of unification with the proof engine has to be solved. Indeed, what to do when unification, called as part of a tactic, solves or refines the current goal by side effect. Somehow, unifyTerms or tclEVARS should take this possibility into consideration, either by forbidding the refinement of the current goal by side effect, or by acknowledging this refinement by producing new subgoals. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16232 85f007b7-540e-0410-9357-904b9bb8a0f7

2013-02-19Dir_path --> DirPathletouzey
Ok, this is merely a matter of taste, but up to now the usage in Coq is rather to use capital letters instead of _ in the names of inner modules. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16221 85f007b7-540e-0410-9357-904b9bb8a0f7
2013-02-19Classops : avoid some use of Gmapletouzey
Gmap uses Pervasives.compare which may interact badly with structures like pairs of kernel names For the moment, we consider elements in classes and coercions only according to their user kernel name: this provides maximal compatibility. But it could be interesting to try using comparision according to canonical kernel names... git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16218 85f007b7-540e-0410-9357-904b9bb8a0f7

2013-02-17Displaying environment and unfolding aliases in "cannot_unify"herbelin
error. Maybe displaying environment is making output overly verbose, but this can also be considered an IDE issue, which would e.g. provide a button to hide/display environment of the error message... Also added some "make_all_name_different" which should probably prevent some anomalies "index to an anonymous variable" at error reporting time. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16208 85f007b7-540e-0410-9357-904b9bb8a0f7
2013-02-17A more informative message when the elimination predicate forherbelin
destruct, rewrite, etc. is not well-typed. Also added support for a more informative message when the elimination predicate is not well-formed while using the smart "second-order" unification algorithm. However the "abstract_list_all" algorithm seems to remain more informative though, so we still use this algorithm for reporting about ill-typed predicates. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16207 85f007b7-540e-0410-9357-904b9bb8a0f7

2013-02-05Revert "Ordered evars by level of dependency in the merging phase of ↵herbelin
unification" Though this commit provides with more "natural" instances of metas found by unification, it breaks a few contribs. The best approach to try is maybe now to instead plug apply on evarconv.ml, rather than on unification.ml! git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16191 85f007b7-540e-0410-9357-904b9bb8a0f7

2013-01-22New implementation of the conversion test, using normalization by evaluation tomdenes
native OCaml code. Warning: the "retroknowledge" mechanism has not been ported to the native compiler, because integers and persistent arrays will ultimately be defined as primitive constructions.

2013-01-22- Fix evarconv so that we have complete eta-conversion:msozeau
- In the maybeflex/rigid (lambda) case, try eta if the maybeflex doesn't actually unfold (e.g. vars, or the transparent state says it's opaque). - In the flexible/rigid(lambda) case, try eta if miller-pfenning fails (as the stack might not be a purely applicative one). This will zip the flexible term (a case construct most likely) and try eta expansion on it. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16134 85f007b7-540e-0410-9357-904b9bb8a0f7

2012-12-17Fixed a bug in the algorithm trying to elaborate a "match" return predicate.herbelin
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
