* Euclidean division for NArithGravatar letouzey2010-02-10
| | | | | | | | | There was already a Ndiv and Nmod, but hiddent in ZOdiv_def. We higlight it by putting it in a separate file, prove its specification without using Z (but for the moment can't avoid a detour via nat, though), and then instantiate general results from Natural/Abstract/NDiv git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12726 85f007b7-540e-0410-9357-904b9bb8a0f7
* Numbers: properties of min/max with respect to 0,S,P,add,sub,mulGravatar letouzey2010-02-09
| | | | | | | | | With these properties, we can kill Arith/MinMax, NArith/Nminmax, and leave ZArith/Zminmax as a compatibility file only. Now the instanciations NPeano.Nat, NBinary.N, ZBinary.Z, BigZ, BigN contains all theses facts. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12718 85f007b7-540e-0410-9357-904b9bb8a0f7

* DoubleCyclic + NMake : typeclasses, more genericity, less ML macro-generationGravatar letouzey2010-02-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Records of operations and specs in CyclicAxioms are now type classes (under a module ZnZ for qualification). We benefit from inference and from generic names: (ZnZ.mul x y) instead of (znz_mul (some_ops...) x y). - Beware of typeclasses unfolds: the line about Typeclasses Opaque w1 w2 ... is critical for decent compilation time (x2.5 without it). - Functions defined via same_level are now obtained from a generic version by (Eval ... in ...) during definition. The code obtained this way should be just as before, apart from some (minor?) details. Proofs for these functions are _way_ simplier and lighter. - The macro-generated NMake_gen.v contains only generic iterators and compare, mul, div_gt, mod_gt. I hope to be able to adapt these functions as well soon. - Spec of comparison is now fully done with respect to Zcompare - A log2 function has been added. - No more unsafe_shiftr, we detect the underflow directly with sub_c git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12713 85f007b7-540e-0410-9357-904b9bb8a0f7

* NMake (and hence BigN): shiftr, shiftl now in the signature NSigGravatar letouzey2010-01-25
| | | | | | | | we export the "safe" version of these functions, working for all input and not only reasonably small shifting arg. The former "unsafe" shiftr and shiftl are now unsafe_shiftr and unsafe_shiftl. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12688 85f007b7-540e-0410-9357-904b9bb8a0f7

* More improvements of BigN, BigZ, BigQ:Gravatar letouzey2010-01-18
| | | | | | | | | | | | | | | - ring/field: detection of constants for ring/field, detection of power, potential use of euclidean division. - for BigN and BigZ, x^n now takes a N as 2nd arg instead of a positive - mention that we can use (r)omega thanks to (ugly) BigN.zify, BigZ.zify. By the way, BigN.zify could still be improved (no insertion of positivity hyps yet, unlike the original zify). - debug of BigQ.qify (autorewrite was looping on spec_0). - for BigQ, start of a generic functor of properties QProperties. - BigQ now implements OrderedType, TotalOrder, and contains facts about min and max. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12681 85f007b7-540e-0410-9357-904b9bb8a0f7
* BigN, BigZ, BigQ: presentation via unique module with both ops and propsGravatar letouzey2010-01-17
| | | | | | | | | | | | | | | | | | | | | We use the <+ operation to regroup all known facts about BigN (resp BigZ, ...) in a unique module. This uses also the new ! feature for controling inlining. By the way, we also make sure that these new BigN and BigZ modules implements OrderedTypeFull and TotalOrder, and also contains facts about min and max (cf. GenericMinMax). Side effects: - In NSig and ZSig, specification of compare and eq_bool is now done with respect to Zcompare and Zeq_bool, as for other ops. The order <= and < are also defined via Zle and Zlt, instead of using compare. Min and max are axiomatized instead of being macros. - Some proofs rework in QMake - QOrderedType and Qminmax were in fact not compiled by make world Still todo: OrderedType + MinMax for BigQ, etc etc git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12680 85f007b7-540e-0410-9357-904b9bb8a0f7

* Numbers: BigN and BigZ get instantiations of all properties about div and modGravatar letouzey2010-01-08
| | | | | | | | | NB: for declaring div and mod as a morphism, even when divisor is zero, I've slightly changed the definition of div_eucl: it now starts by a check of whether the divisor is zero. Not very nice, but this way we can say that BigN.div and BigZ.div _always_ answer like Zdiv.Zdiv. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12646 85f007b7-540e-0410-9357-904b9bb8a0f7
* Include can accept both Module and Module TypeGravatar letouzey2010-01-07
| | | | | | | | Syntax Include Type is still active, but deprecated, and triggers a warning. The syntax M <+ M' <+ M'', which performs internally an Include, also benefits from this: M, M', M'' can be independantly modules or module type. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12640 85f007b7-540e-0410-9357-904b9bb8a0f7

* A generic euclidean division in Numbers (Still Work-In-Progress)Gravatar letouzey2009-12-15
| | | | | | | | | | | - For Z, we propose 3 conventions for the sign of the remainder... - Instanciation for nat in NPeano. - Beginning of instanciation in ZOdiv. Still many proofs to finish, etc, etc, but soon we will have a decent properties database for all divisions of all instances of Numbers (e.g. BigZ). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12590 85f007b7-540e-0410-9357-904b9bb8a0f7
* Fix backtracking heuristic in typeclass resolution. Gravatar msozeau2009-11-30
| | | | | | | | | | | | Now that backtracking is working correctly, we need to avoid a non-termination issue introduced by the [RelCompFun] definition in RelationPairs, by adding a [Measure] typeclass. It could be used to have a uniform notation for measures/interpretations in Numbers and be but in the interfaces too, only the mimimal change was implemented. Fix syntax change in test-suite scripts. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12547 85f007b7-540e-0410-9357-904b9bb8a0f7
* BigQ / BigN / BigZ syntax and scope improvements (sequel to 12504)Gravatar letouzey2009-11-12
| | | | | | | | | | | | | | | | | | | | | | | - In fact, Bind Scope has no retrospective effect. Since we don't want it inside functor, we use it late, and hence we are forced to use manual "Arguments Scope" commands. - Added syntax for power in BigN / BigZ / BigQ. - Added syntax p#q in BigQ for representing fractions (constructor BigQ.Qq) as in QArith. Display of a rational numeral is hence either an integer (constructor BigQ.Qz) or something like 6756 # 8798. - Fix of function BigQ.Qred that was not simplifing (67#1) into 67. - More tests in test-suite/output/NumbersSyntax.v A nice one not in the test-suite: Time Eval vm_compute in BigQ.red ((2/3)^(-100000) * (2/3)^(100000)). = 1 : bigQ Finished transaction in 3. secs (3.284206u,0.004s) :-) git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12507 85f007b7-540e-0410-9357-904b9bb8a0f7
* Repair interpretation of numeral for BigQ, add a printer (close #2160)Gravatar letouzey2009-11-12
| | | | | | | | | | | | | | | on the way: - Added a testsuite output file - Try to avoid nasty unfolding (fix nfun ...) in type of I31. Idealy we would need a "Eval compute in" for the type of a inductive constructor - Stop opening Scopes for BigQ, BigN, BigZ by default The user should do some Open Scope. TODO: there's a bug that prevent BigQ.opp to have arg in bigQ_scope (and so on for other operations), even with some Bind Scope around. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12504 85f007b7-540e-0410-9357-904b9bb8a0f7
* SpecViaZ.NSig: all-in-one spec for [pred] and [sub] based on ZMaxGravatar letouzey2009-11-10
| | | | | | | | To retrieve the old behavior of spec_sub0 and spec_sub with precondition on order, just chain spec_sub with Zmax_r or Zmax_l. Idem with spec_pred0 and spec_pred. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12490 85f007b7-540e-0410-9357-904b9bb8a0f7
* Simplification of Numbers, mainly thanks to IncludeGravatar letouzey2009-11-10
| | | | | | | | | | | | | | | | | - No more nesting of Module and Module Type, we rather use Include. - Instead of in-name-qualification like NZeq, we use uniform short names + modular qualification like N.eq when necessary. - Many simplification of proofs, by some autorewrite for instance - In NZOrder, we instantiate an "order" tactic. - Some requirements in NZAxioms were superfluous: compatibility of le, min and max could be derived from the rest. - NMul removed, since it was containing only an ad-hoc result for ZNatPairs, that we've inlined in the proof of mul_wd there. - Zdomain removed (was already not compiled), idea of a module with eq and eqb reused in DecidableType.BooleanEqualityType. - ZBinDefs don't contain any definition now, migrate it to ZBinary. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12489 85f007b7-540e-0410-9357-904b9bb8a0f7
* Numbers: finish files NStrongRec and NDefOpsGravatar letouzey2009-11-06
| | | | | | | | | | | | | | | | | | - NStrongRec provides a "strong" recursor based on the usual one: recursive calls can be done here on any lower value. See binary log in NDefOps for an example of use. - NDefOps contains alternative definitions of usual operators (add, mul, ltb, pow, even, half, log) via usual or strong recursor, and proofs of correctness and/or of equivalence with axiomatized operators. These files were in the archive but not being compiled, some proofs of correction for functions defined there were missing. By the way, some more iff-style lemmas in Bool. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12476 85f007b7-540e-0410-9357-904b9bb8a0f7
