* [ltac] Warning for deprecated `Add Setoid` and `Add Morphism` forms.Gravatar Emilio Jesus Gallego Arias2017-10-05
| | | | | | | | | | The manual has long stated that these forms are deprecated. We add a warning for them, as indeed `Add Morphism` is an "proof evil" [*] command, and we may want to remove it in the future. We've also fixed the stdlib not to emit the warning.

| | | | | | | | | | | | | | | | | | - For instance, refl_equal --> eq_refl - Npos, Zpos, Zneg now admit more uniform qualified aliases N.pos, Z.pos, Z.neg. - A new module BinInt.Pos2Z with results about injections from positive to Z - A result about Z.pow pushed in the generic layer - Zmult_le_compat_{r,l} --> Z.mul_le_mono_nonneg_{r,l} - Using tactic Z.le_elim instead of Zle_lt_or_eq - Some cleanup in ring, field, micromega (use of "Equivalence", "Proper" ...) - Some adaptions in QArith (for instance changed Qpower.Qpower_decomp) - In ZMake and ZMake, functor parameters are now named NN and ZZ instead of N and Z for avoiding confusions git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15515 85f007b7-540e-0410-9357-904b9bb8a0f7
* Intuition: temporary(?) restore the unconditional unfolding of notGravatar letouzey2012-05-15
| | | | | | | | Let's check tomorrow the impact on contribs: are the recent build failures related to the "not" unfolding stategy or to the new handling of conjonction-like constructors ? git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15330 85f007b7-540e-0410-9357-904b9bb8a0f7
* Fixing tauto "special" behavior on singleton types w/ 2 parameters (bug #2680).Gravatar herbelin2012-04-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - tauto/intuition now works uniformly on and, prod, or, sum, False, Empty_set, unit, True (and isomorphic copies of them), iff, ->, and on all inhabited singleton types with a no-arguments constructor such as "eq t t" (even though the last case goes out of propositional logic: this features is so often used that it is difficult to come back on it). - New dtauto and dintuition works on all inductive types with one constructors and no real arguments (for instance, they work on records such as "Equivalence"), in addition to -> and eq-like types. - Moreover, both of them no longer unfold inner negations (this is a souce of incompatibility for intuition and evaluation of the level of incompatibility on contribs still needs to be done). Incidentally, and amazingly, fixing bug #2680 made that constants InfA_compat and InfA_eqA in SetoidList.v lost one argument: old tauto had indeed destructed a section hypothesis "@StrictOrder A ltA@ thinking it was a conjunction, making this section hypothesis artificially necessary while it was not. Renouncing to the unfolding of inner negations made auto/eauto sometimes succeeding more, sometimes succeeding less. There is by the way a (standard) problem with not in auto/eauto: even when given as an "unfold hint", it works only in goals, not in hypotheses, so that auto is not able to solve something like "forall P, (forall x, ~ P x) -> P 0 -> False". Should we automatically add a lemma of type "HYPS -> A -> False" in the hint database everytime a lemma ""HYPS -> ~A" is declared (and "unfold not" is a hint), and similarly for all unfold hints? At this occasion, also re-did some proofs of Znumtheory. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15180 85f007b7-540e-0410-9357-904b9bb8a0f7
* MSet/FSet/FMap : add more explicitly an alternative spec for fold via fold_rightGravatar letouzey2011-10-14
| | | | | | | | | | | 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

* Merge SetoidList2 into SetoidList.Gravatar letouzey2009-10-19
| | | | | | | | | This file contains low-level stuff for FSets/FMaps. Switching it to the new version (the one using Equivalence and so on instead of eq_refl/eq_sym/eq_trans and so on) only leads to a few changes in FSets/FMaps that are minor and probably invisible to standard users. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12400 85f007b7-540e-0410-9357-904b9bb8a0f7

| | | | | | | | | | | | | - New functions: update (a kind of union), restrict (a kind of inter), diff. - New predicat Partition (and Disjoint), many results about Partition. - Equivalence instead of obsolete Setoid_Theory (they are aliases). refl_st, sym_st, trans_st aren't used anymore and marked as obsolete. - Start using Morphism (E.eq==>...) instead of compat_... This change (FMaps only) is incompatible with 8.2betaX, but it's really better now. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11718 85f007b7-540e-0410-9357-904b9bb8a0f7

* FSet/OrderedType now includes an eq_dec, and hence become an extension of ↵Gravatar letouzey2008-12-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | DecidableType After lots of hesitations, OrderedType now requires this "eq_dec" field, which is redundant (can be deduced from "compare"), but allows the subtyping relation DecidableType <= OrderedType, and hence WS <= S : ordered sets are now truly extensions of weak sets. Of course this change introduces a last-minute incompatibility, but: - There is a clear gain in term of functionnality / simplicity. - FSets 8.2 already needs some adaptations when compared with 8.1, so it's the right time to push such incompatible changes. - Transition shouldn't be too hard: the old OrderedType still exists under the name MiniOrderedType, and functor MOT_to_OT allows to convert from one to the other. Beware, for a FSetInterface.WS (resp. S) to be coercible to a DecidableType (resp. OrderedType), an eq_dec on sets is now required in these interfaces and in the implementations. In pratice, it is really easy to build from equal and equal_1 and equal_2. Some name changes : in FSetFacts, old WFacts now correspond to WFacts_fun, while WFacts now expects only one argument (WFacts M := WFacts_fun M.E M). Idem with WDecide, WProperties and WEqProperties. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11693 85f007b7-540e-0410-9357-904b9bb8a0f7

* Reorganization of FSet+FMap : no more files specific to Weak Sets/MapsGravatar letouzey2008-02-04
| | | | | | | | | | | | | | | | | Thanks to Elie's work and especially "Include Type ...", full sets can be simply expressed as extensions of weak sets. Moreover, Facts and Properties functors can be factorized almost completely. As a result, things like FSetWeakAAA.BBB can now be found as FSetAAA.WBBB, Same with maps / weak maps ... No backward compatibility intended for weak sets / maps, but porting scripts should mostly amounts to name changes (see above). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10505 85f007b7-540e-0410-9357-904b9bb8a0f7

| | | | | | | | | | | | | | | | | | | | | | | | subtype of the FSet Interface (and idem for FMapWeak / FMap). 1) No eq_dec is officially required in FSetWeakInterface.S.E (EqualityType instead of DecidableType). But of course, implementations still needs this eq_dec. 2) elements_3 differs in FSet and FSetWeak (sort vs. nodup). In FSetWeak we rename it into elements_3w, whereas in FSet we artificially add elements_3w along to the original elements_3. Initial steps toward factorization of FSetFacts and FSetWeakFacts, and so on... Even if it's not required, FSetWeakList provides a eq_dec on sets, allowing weak sets of weak sets. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10271 85f007b7-540e-0410-9357-904b9bb8a0f7
