* Changing the type of Ltac values. Now they are toplevel genericGravatar ppedrot2013-06-12

* 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

* Unification: Added a heuristic to solve problems of the formGravatar herbelin2012-03-26
| | | | | | | | | | | | | | | | | | ?x[t1..tm] = ?y[u1..un] when ?x occurs in u1..un with no (easy) way to know if it occurs in rigid position or not. Such equations typically come from matching problems such as "match a return ?T[a] with pair a1 a2 => a1 end" where, a is in type "?A * ?B", and, in the branch, the return clause, of the form "?T[pair ?A ?B a1 a2]", has to be unified with ?A. This possible dependency is kept since commits r15060-15062. The heuristic is to restrict ?T so that the dependency is removed, leading to a behavior similar to the one existing before these commits. This allows BGsection15.v, from contrib Ssreflect, to compile as it did before these commits. Also, removed one function exported without true need in r15061. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15092 85f007b7-540e-0410-9357-904b9bb8a0f7

Concretely, this affects TACTIC EXTEND blocks of the form TACTIC EXTEND foo [ "bar" tactic_opt(tac) -> ... ] | [ "bar" constr_list(tac) -> ... ] where both rules parses "bar" alone but only the first rule must be registered in the atomic table, git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15046 85f007b7-540e-0410-9357-904b9bb8a0f7

* Extraction: replace unicode characters in ident by ascii encodings (fix ↵Gravatar letouzey2010-06-21
| | | | | | | | | | | | | | | | | | | #2158,#2179) Any unicode character above 128 is replaced by __Uxxxx_ where xxxx is the hexa code for the unicode index of this character. For instance <alpha> is turned into __U03b1_. I know, this is ugly. Better solutions are welcome, but I'm afraid we can't do much better as long as ocaml and haskell don't accept unicode letters in idents. At least, this way we're pretty sure this translating won't create name conflit, as long as extraction users avoid __ in their names, something that they should already do btw (see for instance extraction of coinductive types in ocaml). Yes, I should add a test and a warning/error in case of use of __ someday.

* Add (almost) compatibility with camlp4, without breaking support for camlp5Gravatar letouzey2010-05-19
| | | | | | | | | | | | | | | | | | | | | | | The choice between camlp4/5 is done during configure with flags -usecamlp5 (default for the moment) vs. -usecamlp4. Currently, to have a full camlp4 compatibility, you need to change all "EXTEND" and "GEXTEND Gram" into "EXTEND Gram", and change "EOI" into "`EOI" in grammar entries. I've a sed script that does that (actually the converse), but I prefer to re-think it and check a few things before branching this sed into the build mechanism. lib/compat.ml4 is heavily used to hide incompatibilities between camlp4/5 and try to propose a common interface (cf LexerSig / GrammarSig). A few incompatible quotations have been turned into underlying code manually, in order to make the IFDEF CAMLP5 THEN ... ELSE ... END parsable by both camlp4 and 5. See in particular the fate of <:str_item< declare ... end >> Stdpp isn't used anymore, but rather Ploc (hidden behind local module Loc). This forces to use camlp5 > 5.01. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13019 85f007b7-540e-0410-9357-904b9bb8a0f7

| | | | | | | | | | | | Cf tok.ml, token isn't anymore string*string where first string encodes the kind of the token, but rather a nice sum type. Unfortunately, string*string (a.k.a Plexing.pattern) is still used in some places of Camlp5, so there's a few conversions back and forth. But the penalty should be quite low, and having nicer tokens helps in the forthcoming integration of support for camlp4 post 3.10 git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13018 85f007b7-540e-0410-9357-904b9bb8a0f7

* Reduced the complexity of evar instantiations from O(n^3) to less than O(n^2).Gravatar herbelin2010-04-19
| | | | | | | | | | | | | | Reasoning modulo variable aliases induced an extra lookup in the environment at each inversion of the components of the evar instances: precomputing the aliases map allowed to gain a factor n. Moreover, solve_evar_evar_l2r was recomputing the evar substitution from the evar instance n more times than needed. Function solve_evar_evar_l2r is still on O(n^2) but it does not seem to be used so often actually. The trivial case has been optimized (linear time) but the general case could probably be also cut down to O(n*log(n)) if needed. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12954 85f007b7-540e-0410-9357-904b9bb8a0f7
