2014-04-23Better representation of evar filters: we represent the vacuous filters ofPierre-Marie Pédrot
any length with a [None] representation and ensure that this representation is canonical through the restricted interface.
2014-03-05Remove some dead-code (thanks to ocaml warnings)Pierre Letouzey
The removed code isn't used locally and isn't exported in the signature
2014-03-05Remove many superfluous 'open' indicated by ocamlc -w +33Pierre Letouzey
With ocaml 4.01, the 'unused open' warning also checks the mli :-) Beware: some open are reported as useless when compiling with camlp5, but are necessary for compatibility with camlp4. These open are now marked with a comment.

2013-12-03Removing useless meta-related functions.Pierre-Marie Pédrot
2013-11-30Better heuristic for name generation backward compatibility. We fallbackPierre-Marie Pédrot
to old behaviour whenever we were in Program mode.
2013-11-30Tentative fix to recover fresh name generation as it was beforePierre-Marie Pédrot
new-tacticals merge. This is essentially a revert of 6fea2f which broke the sacrosanct backward compatibility of name generation, thus breaking quite a lot of contribs.
2013-11-25Factoring: is_section_variable.Arnaud Spiwack
In 0c7a77, I inadvertantly re-defined an is_section_variable function.
2013-11-06Less partial applications in Vars, as well as better memory allocation.ppedrot

2013-11-04Nicer infered names in refine.aspiwack
When an existential variable is created, the rel context becomes a named context, and identifiers are given to anonymous variables. Instead of using an identifier based on "H" all the time, use an identifier based on the lower case first letter of the type. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@17060 85f007b7-540e-0410-9357-904b9bb8a0f7
2013-11-02push_rel_context: do not rename section variables.aspiwack
Renaming section variables is incorrect. And interacts badly with Hints and Canonical Structures in sections. (bug noticed in ssreflect) git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@17024 85f007b7-540e-0410-9357-904b9bb8a0f7
2013-11-02A newly introduced variable inside a named context is no longer α-renamed.aspiwack
Instead, in case of collision, the older name is substituted for a fresh one. It should also be made inaccessible from the user, but I'll leave this for later. The goal is to guarantee that [refine (fun x => _)] introduces a binder named [x]. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16972 85f007b7-540e-0410-9357-904b9bb8a0f7

2013-10-22Optimizing evar filters. It seems to cost quite a lot in unification,ppedrot
as witnessed by profiling on time-consuming files. I suspect we can do better by using a smarter representation. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16912 85f007b7-540e-0410-9357-904b9bb8a0f7

2013-09-18At least made the evar type opaque! There are still 5 remaining unsafeppedrot
casts of ints to evars. - 2 in Evarutil and Goal which are really needed, even though the Goal one could (and should) be removed; - 2 in G_xml and Detyping that are there for completeness sake, but that might be made anomalies altogether; - 1 in Newring which is quite dubious at best, and should be fixed. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16786 85f007b7-540e-0410-9357-904b9bb8a0f7
2013-09-18Removing almost all new_untyped_evar, and a bunch of Evd.add.ppedrot
Ultimately all evars should be created with respect to a given evar map, instead of using a global counter. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16783 85f007b7-540e-0410-9357-904b9bb8a0f7

2013-09-03Partly replacing list-based access functions in Evd. This is stillppedrot
unsatisfactory as some functions implicitly require some ordering on the evars, but this is already better. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16759 85f007b7-540e-0410-9357-904b9bb8a0f7

2013-04-29Splitting Term into five unrelated interfaces:ppedrot
1. sorts.ml: A small file utility for sorts; 2. constr.ml: Really low-level terms, essentially kind_of_constr, smart constructor and basic operators; 3. vars.ml: Everything related to term variables, that is, occurences and substitution; 4. context.ml: Rel/Named context and all that; 5. term.ml: derived utility operations on terms; also includes constr.ml up to some renaming, and acts as a compatibility layer, to be deprecated. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16462 85f007b7-540e-0410-9357-904b9bb8a0f7
2013-04-22code simplifications concerning Summaryletouzey
- Most of the time, the table registered via Summary.declare_summary is just a single reference. A new function Summary.ref now allows to both declare this ref and register it to summary in one shot. - Clarifications concerning the role of [init_function]. For statically registered tables that don't need a special initializer, just do nothing there (see the new Summary.nop function). Beware: now that Summary exports a function named "ref", any code that do an "open Summary" will probably fail to compile. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16441 85f007b7-540e-0410-9357-904b9bb8a0f7

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.

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
