Add headers to a few files which were missing them.
2019-08-26Make kernel parametric on the lowest universe and fix #9294Matthieu Sozeau
This could be Prop (for compat with usual Coq), Set (for HoTT), or actually an arbitrary "i". Take lower bound of universes into account in pretyping/engine Reinstate proper elaboration of SProp <= l constraints: replacing is_small with equality with lbound is _not_ semantics preserving! lbound = Set Elaborate template polymorphic inductives with lower bound Prop This will make more constraints explicit Check univ constraints with Prop as lower bound for template inductives Restrict template polymorphic universes to those not bounded from below Fixes #9294 fix suggested by Matthieu Try second fix suggested by Matthieu Take care of modifying elaboration for record declarations as well. Rebase and export functions for debug Remove exported functions used while debugging Add a new typing flag "check_template" and option "-no-template-checl" This parameterizes the new criterion on template polymorphic inductives to allow bypassing it (necessary for backward compatibility). Update checker to the new typing flags structure Switch on the new template_check flag to allow old unsafe behavior in indTyping. This is the only change of code really impacting the kernel, together with the commit implementing unbounded from below and parameterization by the lower bound on universes. Add deprecated option `Unset Template Check` allowing to make proof scripts work with both 8.9 and 8.10 for a while Fix `Template Check` option name and test it Add `Unset Template Check` to Coq89.v Cooking of inductives and template-check tests Cleanup test-suite file for template check / universes(template) flags cookind tests Move test of `Unset Template Check` to the failure/ dir, but comment it for now Template test-suite test explanation Overlays for PR 9918 Overlay for paramcoq Add overlay for fiat_parsers (-no-template-check) Add overlay for fiat_crypto_legacy Update fiat-crypto legacy overlay Now it points at the version that I plan on merging; I am hoping that doing this will guard against mistakes by adding an extra check that the target tested by Coq's CI on this branch works with the change I made. Remove overlay that should no longer be necessary The setting in the compat file should handle it Remove now-merged fiat-crypto-legacy overlay Update `Print Assumptions` to reflect the typing flag for template checking Fix About and Print Assumptions for template poly, giving info on which variables are actually polymorphic Fix pretty printing to print global universe levels properly Fix printing of template polymorphic universes Fix pretty printing for template polymorphism on no universe Fix interaction of template check and universes(template) flag Fix indTyping to really check if there is any point in polymorphism: the conclusion sort should be parameterized over at least one local universe Indtyping fixes for template polymorphic Props Allow explicit template polymorphism again Adapt to new indTyping interface Handle the case of template-polymorphic on no universes correctly (morally Type0m univ represented as Prop). Fix check of meaningfullness of template polymorphism in the kernel. It is now done w.r.t the min_univ, the minimal universe inferred for the inductive/record type, independently of the user-written annotation which must only be larger than min_univ. This preserves compatibility with UniMath and template-polymorphism as it has been implemented up-to now. Comment on identity non-template-polymorphism Remove incorrect universes(template) attributes from ssr simpl_fun can be meaningfully template-poly, as well as pred_key (although the use is debatable: it could just as well be in Prop). Move `fun_of_simpl` coercion declaration out of section to respect uniform inheritance Remove incorrect uses of #[universes(template)] from the stdlib Extraction of micromega changes due to moving an ind decl out of a section Remove incorrect uses of #[universes(template)] from plugins Fix test-suite files, removing incorrect #[universes(template)] attributes Remove incorrect #[universes(template)] attributes in test-suite Fix test-suite Remove overlays as they have been merged upstream.

2018-11-14Deprecate hint declaration/removal with no specified databaseMaxime Dénès
Previously, hints added without a specified database where implicitly put in the "core" database, which was discouraged by the user manual (because of the lack of modularity of this approach).

2018-02-27Update headers following #6543.Théo Zimmermann
2017-06-14Prelude : no more autoload of plugins extraction and recdefPierre Letouzey
The user now has to manually load them, respectively via: Require Extraction Require Import FunInd The "Import" in the case of FunInd is to ensure that the tactics functional induction and functional inversion are indeed in scope. Note that the Recdef.v file is still there as well (it contains complements used when doing Function with measures), and it also triggers a load of FunInd.v. This change is correctly documented in the refman, and the test-suite has been adapted.
2016-06-03Removing "intro" from the tactic AST.Pierre-Marie Pédrot
Note that this breaks the compatibility, in a beneficial way I believe. Tactics defined in strict mode (i.e. through Ltac foo := ...) may not do an introduction on a local identifier anymore. They must use the "fresh" primitive instead.
2015-04-02ZArith/Int.v: some modernizationsPierre Letouzey
2014-08-25"allows to", like "allowing to", is improperJason Gross
It's possible that I should have removed more "allows", as many instances of "foo allows to bar" could have been replaced by "foo bars" (e.g., "[Qed] allows to check and save a complete proof term" could be "[Qed] checks and saves a complete proof term"), but not always (e.g., "the optional argument allows to ignore universe polymorphism" should not be "the optional argument ignores universe polymorphism" but "the optional argument allows the caller to instruct Coq to ignore universe polymorphism" or something similar).

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
2012-04-13MSetRBT : 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

2011-05-05Modularization 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

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

2009-11-03OrderedType implementation for various numerical datatypes + min/max structuresletouzey
- A richer OrderedTypeFull interface : OrderedType + predicate "le" - Implementations {Nat,N,P,Z,Q}OrderedType.v, also providing "order" tactics - By the way: as suggested by S. 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
2009-10-16OrderedType2 : trivial lemmas are turned into tests for order.letouzey
In particular we remove them from the hint db, a few autos become calls to order. Moreover, lt_antirefl --> lt_irrefl for uniformity. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12398 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-10-13MSets: a new generation of FSetsletouzey
Same global ideas (in particular the use of modules/functors), but: - frequent use of Type Classes inside interfaces/implementation. For instance, no more eq_refl/eq_sym/eq_trans, but Equivalence. A class StrictOrder for lt in OrderedType. Extensive use of Proper and rewrite. - now that rewrite is mature, we write specifications of set operators via iff instead of many separate requirements based on ->. For instance add_spec : In y (add x s) <-> E.eq y x \/ In x s. Old-style specs are available in the functor Facts. - compare is now a pure function (t -> t -> comparison) instead of returning a dependent type Compare. - The "Raw" functors (the ones dealing with e.g. list with no sortedness proofs yet, but morally sorted when operating on them) are given proper interfaces and a generic functor allows to obtain a regular set implementation out of a "raw" one. The last two points allow to manipulate set objects that are completely free of proof-parts if one wants to. Later proofs will rely on type-classes instance search mechanism. No need to emphasis the fact that this new version is severely incompatible with the earlier one. I've no precise ideas yet on how allowing an easy transition (functors ?). For the moment, these new Sets are placed alongside the old ones, in directory MSets (M for Modular, to constrast with forthcoming CSets, see below). A few files exist currently in version foo.v and foo2.v, I'll try to merge them without breaking things. Old FSets will probably move to a contrib later. Still to be done: - adapt FMap in the same way - integrate misc stuff like multisets or the map function - CSets, i.e. Sets based on Type Classes : Integration of code contributed by S. Lescuyer is on the way. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12384 85f007b7-540e-0410-9357-904b9bb8a0f7
