2012-03-26Unification: Added a heuristic to solve problems of the formherbelin
?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

2012-03-18Yet another subtlety with bug 2732: when several grammar rules of aherbelin
TACTIC EXTEND block possibly parse the stand-alone name of a tactic, then only the first rule must be registered in the atomic tactic table so as to be consistent with what happens when the tactic is invoked directly via its parsing rules and not via the interpretation of a reference in the atomic tactic table. 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

2011-05-17More work on error handlingletouzey
Anomalies are now meant to be the exceptions that are *not* catched and handled by the new Errors.handle_stack. Three variants of [Errors.print] allow to customize how anomalies are treated. In particular, [Errors.print_no_anomaly] is used for the Fail command, instead of a classification function Cerrors.is_user_error which wasn't customizable. No more AnomalyOnError, its only occurrence is now a regular anomaly git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14133 85f007b7-540e-0410-9357-904b9bb8a0f7

2010-06-21Extraction: replace unicode characters in ident by ascii encodings (fix ↵letouzey
#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.

2010-05-19Add (almost) compatibility with camlp4, without breaking support for camlp5letouzey
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
2010-05-19Nicer representation of tokens, more independant of camlp*letouzey
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

2010-04-19Reduced the complexity of evar instantiations from O(n^3) to less than O(n^2).herbelin
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

2009-10-28Integrate a few improvements on typeclasses and Program from the equations ↵msozeau
branch and remove equations stuff which moves to a separate plugin.

Tactics and proofs: - Change [revert] so that it keeps let-ins (but not [generalize]). - Various improvements to the [generalize_eqs] tactic to make it more robust and produce the smallest proof terms possible. Move [specialize_hypothesis] in tactics.ml as it goes hand in hand with [generalize_eqs]. - A few new general purpose tactics in Program.Tactics like [revert_until] - Make transitive closure well-foundedness proofs transparent. - More uniform testing for metas/evars in pretyping/unification.ml (might introduce a few changes in the contribs). Program: - Better sorting of dependencies in obligations. - Ability to start a Program definition from just a type and no obligations, automatically adding an obligation for this type. - In compilation of Program's well-founded definitions, make the functional a separate definition for easier reasoning. - Add a hint database for every Program populated by [Hint Unfold]s for every defined obligation constant. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12440 85f007b7-540e-0410-9357-904b9bb8a0f7
