2020-02-13[build] Consolidate stdlib's .v files under a single directory.Emilio Jesus Gallego Arias
Currently, `.v` under the `Coq.` prefix are found in both `theories` and `plugins`. Usually these two directories are merged by special loadpath code that allows double-binding of the prefix. This adds some complexity to the build and loadpath system; and in particular, it prevents from handling the `Coq.*` prefix in the simple, `-R theories Coq` standard way. We thus move all `.v` files to theories, leaving `plugins` as an OCaml-only directory, and modify accordingly the loadpath / build infrastructure. Note that in general `plugins/foo/Foo.v` was not self-contained, in the sense that it depended on files in `theories` and files in `theories` depended on it; moreover, Coq saw all these files as belonging to the same namespace so it didn't really care where they lived. This could also imply a performance gain as we now effectively traverse less directories when locating a library. See also discussion in #10003
2019-12-17[micromega] fix efficiency regressionFrédéric Besson
PR #9725 fixes completness bugs introduces some inefficiency. The current PR intends to fix the inefficiency while retaining completness. The fix removes a pre-processing step and instead relies on a more elaborate proof format introducing positivity constraints on the fly. Solve bootstrapping issues: RMicromega <-> Rbase <-> lia. Fixes #11063 and fixes #11242 and fixes #11270

2019-10-21Improvements of zifyFrédéric Besson
- Fix reification of overloaded operators (triggers convertibility checks with existing terms) - Zify instances need not be in hnf - Fix specification of bool operators - Add (limited) support for comparison fixes #10779
2019-09-16Re-implementation of zifyFrédéric Besson
The logic is implemented in OCaml. By induction over the terms, guided by registered Coq terms in ZifyInst.v, it generates a rewriting lemma. The rewriting is only performed if there is some progress. If the rewriting fails (due to dependencies), a novel hypothesis is generated. This PR fixes #5155, fixes #8898, fixes #7886, fixes #10707, fixes #9848 ans fixes #10755. The zify plugin is placed in the micromega directory. (Though the reason is unclear, having it in a separate directory is bad for efficiency.) efficiency impact. There are also a few improvements of lia/lra that are piggybacked. - more aggressive pruning of useless hypotheses - slightly optimised conjunctive normal form - applies exfalso if conclusion is not in Prop - removal of Timeout in test-suite

2019-04-01Several improvements and fixes of LiaFrédéric Besson
- Improved reification for Micromega (support for #8764) - Fixes #9268: Do not take universes into account in lia reification Improve #9291 by threading the evar_map during reification. Universes are unified. - Remove (potentially cyclic) dependency over lra for Rle_abs - Towards a complete simplex-based lia fixes #9615 Lia is now exclusively using cutting plane proofs. For this to always work, all the variables need to be positive. Therefore, lia is pre-processing the goal for each variable x it introduces the constraints x = y - z , y>=0 , z >= 0 for some fresh variable y and z. For scalability, nia is currently NOT performing this pre-processing. - Lia is using the FSet library manual merge of commit #230899e87c51c12b2f21b6fedc414d099a1425e4 to work around a "leaked" hint breaking compatibility of eauto

2012-07-05ZArith + other : favor the use of modern names instead of compat notationsletouzey
- 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

2010-11-18Some more revision of {P,N,Z}Arith + bitwise ops in Ndigitsletouzey
Initial plan was only to add shiftl/shiftr/land/... to N and other number type, this is only partly done, but this work has diverged into a big reorganisation and improvement session of PArith,NArith,ZArith. Bool/Bool: add lemmas orb_diag (a||a = a) and andb_diag (a&&a = a) PArith/BinPos: - added a power function Ppow - iterator iter_pos moved from Zmisc to here + some lemmas - added Psize_pos, which is 1+log2, used to define Nlog2/Zlog2 - more lemmas on Pcompare and succ/+/* and order, allow to simplify a lot some old proofs elsewhere. - new/revised results on Pminus (including some direct proof of stuff from Pnat) PArith/Pnat: - more direct proofs (limit the need of stuff about Pmult_nat). - provide nicer names for some lemmas (eg. Pplus_plus instead of nat_of_P_plus_morphism), compatibility notations provided. - kill some too-specific lemmas unused in stdlib + contribs NArith/BinNat: - N_of_nat, nat_of_N moved from Nnat to here. - a lemma relating Npred and Nminus - revised definitions and specification proofs of Npow and Nlog2 NArith/Nnat: - shorter proofs. - stuff about Z_of_N is moved to Znat. This way, NArith is entirely independent from ZArith. NArith/Ndigits: - added bitwise operations Nand Nor Ndiff Nshiftl Nshiftr - revised proofs about Nxor, still using functional bit stream - use the same approach to prove properties of Nand Nor Ndiff ZArith/BinInt: huge simplification of Zplus_assoc + cosmetic stuff ZArith/Zcompare: nicer proofs of ugly things like Zcompare_Zplus_compat ZArith/Znat: some nicer proofs and names, received stuff about Z_of_N ZArith/Zmisc: almost empty new, only contain stuff about badly-named iter. Should be reformed more someday. ZArith/Zlog_def: Zlog2 is now based on Psize_pos, this factorizes proofs and avoid slowdown due to adding 1 in Z instead of in positive Zarith/Zpow_def: Zpower_opt is renamed more modestly Zpower_alt as long as I dont't know why it's slower on powers of two. Elsewhere: propagate new names + some nicer proofs NB: Impact on compatibility is probably non-zero, but should be really moderate. We'll see on contribs, but a few Require here and there might be necessary. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13651 85f007b7-540e-0410-9357-904b9bb8a0f7
