2020-11-16Explicitly annotate all hint declarations of the standard library.Pierre-Marie Pédrot
By default Coq stdlib warnings raise an error, so this is really required.
2020-03-18Update headers in the whole code base.Théo Zimmermann
Add headers to a few files which were missing them.
2019-06-17Update ml-style headers to new year.Théo Zimmermann
2019-04-02Remove -compat 8.7Jason Gross
This removes various compatibility notations. Closes #8374 This commit was mostly created by running `./dev/tools/update-compat.py --release`. There's a bit of manual spacing adjustment around all of the removed compatibility notations, and some test-suite updates were done manually. The update to CHANGES.md was manual.
2018-10-02Update compat notations to be compat 8.7Jason Gross
All changes done with ``` git grep --name-only 'compat "8.6"' | xargs sed -i s'/compat "8.6"/compat "8.7"/g' ``` As per https://github.com/coq/coq/pull/8374#issuecomment-426202818 and https://github.com/coq/coq/issues/8383#issuecomment-426200497
2018-03-05Merge PR #6855: Update headers following #6543.Maxime Dénès
2018-03-02Remove the deprecation for some 8.2-8.5 compatibility aliases.Théo Zimmermann
This was decided during the Fall WG (2017). The aliases that are kept as deprecated are the ones where the difference is only a prefix becoming a qualified module name. The intention is to turn the warning for deprecated notations on. We change the compat version to 8.6 to allow the removal of VOld and V8_5.

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
2012-07-05Notation: a new annotation "compat 8.x" extending "only parsing"letouzey
Suppose we declare : Notation foo := bar (compat "8.3"). Then each time foo is used in a script : - By default nothing particular happens (for the moment) - But we could get a warning explaining that "foo is bar since coq > 8.3". For that, either use the command-line option -verb-compat-notations or the interactive command "Set Verbose Compat Notations". - There is also a strict mode, where foo is forbidden : the previous warning is now an error. For that, either use the command-line option -no-compat-notations or the interactive command "Unset Compat Notations". When Coq is launched in compatibility mode (via -compat 8.x), using a notation tagged "8.x" will never trigger a warning or error. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15514 85f007b7-540e-0410-9357-904b9bb8a0f7

2011-05-05BinInt: Z.add become the alternative Z.add'letouzey
It relies on Z.pos_sub instead of a Pos.compare followed by Pos.sub. Proofs seem to be quite easy to adapt, via some rewrite Z.pos_sub_spec. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14107 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
2010-12-09ZArith: for uniformity, Zdiv2 becomes Zquot2 while Zdiv2' becomes Zdiv2letouzey
Now we have: - Zdiv and Zdiv2 : round toward bottom, no easy sign rule, remainder of a/2 is 0 or 1, operations related with two's-complement Zshiftr. - Zquot and Zquot2 : round toward zero, Zquot2 (-a) = - Zquot2 a, remainder of a/2 is 0 or Zsgn a. Ok, I'm introducing an incompatibility here, but I think coherence is really desirable. Anyway, people using Zdiv on positive numbers only shouldn't even notice the change. Otherwise, it's just a matter of sed -e "s/div2/quot2/g". git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13695 85f007b7-540e-0410-9357-904b9bb8a0f7
2010-12-06Numbers and bitwise functions.letouzey
See NatInt/NZBits.v for the common axiomatization of bitwise functions over naturals / integers. Some specs aren't pretty, but easier to prove, see alternate statements in property functors {N,Z}Bits. Negative numbers are considered via the two's complement convention. We provide implementations for N (in Ndigits.v), for nat (quite dummy, just for completeness), for Z (new file Zdigits_def), for BigN (for the moment partly by converting to N, to be improved soon) and for BigZ. NOTA: For BigN.shiftl and BigN.shiftr, the two arguments are now in the reversed order (for consistency with the rest of the world): for instance BigN.shiftl 1 10 is 2^10. NOTA2: Zeven.Zdiv2 is _not_ doing (Zdiv _ 2), but rather (Zquot _ 2) on negative numbers. For the moment I've kept it intact, and have just added a Zdiv2' which is truly equivalent to (Zdiv _ 2). To reorganize someday ? git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13689 85f007b7-540e-0410-9357-904b9bb8a0f7

2010-04-29Remove the svn-specific $Id$ annotationsletouzey
- Many of them were broken, some of them after Pierre B's rework of mli for ocamldoc, but not only (many bad annotation, many files with no svn property about Id, etc) - Useless for those of us that work with git-svn (and a fortiori in a forthcoming git-only setting) - Even in svn, they seem to be of little interest git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12972 85f007b7-540e-0410-9357-904b9bb8a0f7

2007-11-06Integration of theories/Ints/Z/* in ZArith and large cleanup and extension ↵letouzey
of Zdiv Some details: - ZAux.v is the only file left in Ints/Z. The few elements that remain in it are rather specific or compatibility oriented. Others parts and files have been either deleted when unused or pushed into some place of ZArith. - Ints/List/ is removed since it was not needed anymore - Ints/Tactic.v disappear: some of its tactic were unused, some already in Tactics.v (case_eq, f_equal instead of eq_tac), and the nice contradict has been added to Tactics.v - Znumtheory inherits lots of results about Zdivide, rel_prime, prime, Zgcd, ... - A new file Zpow_facts inherits lots of results about Zpower. Placing them into Zpower would have been difficult with respect to compatibility (import of ring) - A few things added to Zmax, Zabs, Znat, Zsqrt, Zeven, Zorder - Adequate adaptations to Ints/num/* (mainly renaming of lemmas) Now, concerning Zdiv, the behavior when dividing by a negative number is now fully proved. When this was possible, existing lemmas has been extended, either from strictly positive to non-zero divisor, or even to arbitrary divisor (especially when playing with Zmod). These extended lemmas are named with the suffix _full, whereas the original restrictive lemmas are retained for compatibility. Several lemmas now have shorter proofs (based on unicity lemmas). Lemmas are now more or less organized by themes (division and order, division and usual operations, etc). Three possible choices of spec for divisions on negative numbers are presented: this Zdiv, the ocaml approach and the remainder-always-positive approach. The ugly behavior of Zopp with the current choice of Zdiv/Zmod is now fully covered. A embryo of division "a la Ocaml" is given: Odiv and Omod. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10291 85f007b7-540e-0410-9357-904b9bb8a0f7
