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

2012-07-09induction/destruct : nicer syntax for generating equations (solves #2741)letouzey
The ugly syntax "destruct x as [ ]_eqn:H" is replaced by: destruct x eqn:H destruct x as [ ] eqn:H Some with induction. Of course, the pattern behind "as" is arbitrary. For an anonymous version, H could be replaced by ?. The old syntax with "_eqn" still works for the moment, by triggers a warning. For making this new syntax work, we had to change the seldom-used "induction x y z using foo" into "induction x, y, z using foo". Now, only one "using" can be used per command instead of one per comma-separated group earlier, but I doubt this will bother anyone. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15566 85f007b7-540e-0410-9357-904b9bb8a0f7

2012-04-13MSetRBT : implementation of MSets via Red-Black treesletouzey
Initial contribution by Andrew Appel, many ulterior modifications by myself. Interest: red-black trees maintain logarithmic depths as AVL, but they do not rely on integer height annotations as AVL, allowing interesting performance when computing in Coq or after standard extraction. More on this topic in the article by A. Appel. The common parts of MSetAVL and MSetRBT are shared in a new file MSetGenTree which include the definition of tree and functions such as mem fold elements compare subset. Note that the height of AVL trees is now the first arg of the Node constructor instead of the last one. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15168 85f007b7-540e-0410-9357-904b9bb8a0f7

2011-10-14MSet/FSet/FMap : add more explicitly an alternative spec for fold via fold_rightletouzey
In fact, this formula "fold ... = fold_right ... (rev (elements))" was already frequently used, but without ever stating it explicitely. Instead, we were always chaining two rewrites each time. Thanks to A. Appel for mentionning this question of fold_right vs. fold_left in the spec of fold. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14561 85f007b7-540e-0410-9357-904b9bb8a0f7

2011-10-07Improved handling of element equalities in fsetdec (fix #2467)letouzey
- We now handle things like (H : E.eq x x -> ...) by rewriting E.eq x x into True. - There was also a confusion between E.t and its various equivalent (but syntactically different) forms. This should be solved by preventing inlining during an inner functor application. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14520 85f007b7-540e-0410-9357-904b9bb8a0f7
2011-05-05Modularization of BinInt, related fixes in the stdlibletouzey
All the functions about Z is now in a separated file BinIntDef, which is Included in BinInt.Z. This BinInt.Z directly implements ZAxiomsSig, and instantiates derived properties ZProp. Note that we refer to Z instead of t inside BinInt.Z, otherwise ring breaks later on @eq Z.t git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14106 85f007b7-540e-0410-9357-904b9bb8a0f7
2011-03-17CompareSpec: a slight generalization/reformulation of CompSpecletouzey
CompareSpec expects 3 propositions Peq Plt Pgt instead of 2 relations eq lt and 2 points x y. For the moment, we still always use (Peq=eq x y), (Plt=lt x y) (Pgt=lt y x), but this may not be always the case, especially for Pgt. The former CompSpec is now defined in term of CompareSpec. Compatibility is preserved (except maybe a rare unfold or red to break the CompSpec definition). Typically, CompareSpec looks nicer when we have infix notations, e.g. forall x y, CompareSpec (x=y) (x<y) (y<x) (x?=x) while CompSpec is shorter when we directly refer to predicates: forall x y, CompSpec eq lt x y (compare x y) git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13914 85f007b7-540e-0410-9357-904b9bb8a0f7
2011-03-13- Add modulo_delta_types flag for unification to allow fullmsozeau
conversion when checking types of instanciations while having restricted delta reduction for unification itself. This makes auto/eauto... backward compatible. - Change semantics of [Instance foo : C a.] to _not_ search for an instance of [C a] automatically and potentially slow down interaction, except for trivial classes with no fields. Use [C a := _.] or [C a := {}] to search for an instance of the class or for every field. - Correct treatment of transparency information for classes declared in sections. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13908 85f007b7-540e-0410-9357-904b9bb8a0f7

2010-09-20Extraction: re-introduce some eta-expansions in rare situations leading to ↵letouzey
'_a types If there's no lambdas at the top of a constant body and its type is functional and this type contains type variable and we're extracting to Ocaml then we perform one eta-expansion to please the ML type-checker This might slow down things, if some computations are shared thanks to the partial application. But it seems quite unlikely to encounter both situations (clever partial application and non-generalizable variable) at the same time. Compcert is ok, for instance. As a consequence, no need for manual eta-expansion in AVL code (and by the way MSetAVL.element wasn't a problem, it is monomorphic) git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13441 85f007b7-540e-0410-9357-904b9bb8a0f7

2010-02-12CompSpecType, a clone of CompSpec but in Type instead of Propletouzey
In interfaces fields like compare_spec, a CompSpec is prefered to get nice extraction, but then no "destruct (compare_spec .. ..)" is possible in a Type context. Now you can say there "destruct (CompSpec2Type (compare_spec ... ...))"

Lescuyer, specification of compare is now inductive - GenericMinMax: axiomatisation + properties of min and max out of OrderedTypeFull structures. - MinMax.v, {Z,P,N,Q}minmax.v are specialization of GenericMinMax, with also some domain-specific results, and compatibility layer with already existing results. - Some ML code of plugins had to be adapted, otherwise wrong "eq", "lt" or simimlar constants were found by functions like coq_constant. - Beware of the aliasing problems: for instance eq:=@eq t instead of eq:=@eq M.t in Make_UDT made (r)omega stopped working (Z_as_OT.t instead of Z in statement of Zmax_spec). - Some Morphism declaration are now ambiguous: switch to new syntax anyway. - Misc adaptations of FSets/MSets - Classes/RelationPairs.v: from two relations over A and B, we inspect relations over A*B and their properties in terms of classes. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12461 85f007b7-540e-0410-9357-904b9bb8a0f7

2009-10-16Structure/OrderTac.v : highlight the "order" tactic by isolating it from ↵letouzey
FSets, and improve it As soon as you have a eq, a lt and a le (that may be lt\/eq, or (complement (flip (lt))) and a few basic properties over them, you can instantiate functor MakeOrderTac and gain an "order" tactic. See comments in the file for the scope of this tactic. NB: order doesn't call auto anymore. It only searches for a contradiction in the current set of (in)equalities (after the goal was optionally turned into hyp by double negation). Thanks to S.
