2016-09-26Partial fix for bug #5085: nsatz_compute stack overflows.Pierre-Marie Pédrot
This fixes the stack overflow part of the bug, even if the tactic is still quite slow. The offending functions have been written in a tail-recursive way.

2016-07-06improved complexity in nsatzthery
we use a hashtable to reduce the complexity of creating a duplicate-free list.
2016-07-06Bug Fixes : 4851 4858 4880 for nsatzthery
the function in_ideal of ideal.ml supposes the list of polynomials does not contain zero and is duplicate free. I force this invariant in the call of in_ideal in nsatz.ml4 the function clean_pol returns the reduced list plus a list of booleans that indicates which polynomials have been deleted the function expand_pol translates back the certificate of the reduced to list to the complete list thanks to the list of booleans. The fix is quadratic with respect to the input list which should be ok for reasonable usage of nsatz. If there is some performance issue we could improve the in_pol function.

2016-06-08Compilation via pack for plugins of the stdlibPierre Letouzey
For now, the pack name reuse the previous .cma name of the plugin, (extraction_plugin, etc). The earlier .mllib files in plugins are now named .mlpack. They are also handled by bin/ocamllibdep, just as .mllib. We've slightly modified ocamllibdep to help setting the -for-pack options: in *.mlpack.d files, there are some extra variables such as foo/bar_FORPACK := -for-pack Baz when foo/bar.ml is mentioned in baz.mlpack. When a plugin is calling a function from another plugin, the name need to be qualified (Foo_plugin.Bar.baz instead of Bar.baz). Btw, we discard the generated files plugins/*/*_mod.ml, they are obsolete now, replaced by DECLARE PLUGIN. Nota: there's a potential problem in the micromega directory, some .ml files are linked both in micromega_plugin and in csdpcert. And we now compile these files with a -for-pack, even if they are not packed in the case of csdpcert. In practice, csdpcert seems to work well, but we should verify with OCaml experts.

2014-12-09Switch the few remaining iso-latin-1 files to utf8Pierre Letouzey
2014-05-12Now parsing rules of ML-declared tactics are only made available after thePierre-Marie Pédrot
corresponding Declare ML Module command. This changes essentially two things: 1. ML plugins are forced to use the DECLARE PLUGIN statement before any TACTIC EXTEND statement. The plugin name must be exactly the string passed to the Declare ML Module command. 2. ML tactics are only made available after the Coq module that does the corresponding Declare ML Module is imported. This may break a few things, as it already broke quite some uses of omega in the stdlib.
2014-03-05Remove some dead-code (thanks to ocaml warnings)Pierre Letouzey
The removed code isn't used locally and isn't exported in the signature
2013-11-02Makes the new Proofview.tactic the basic type of Ltac.aspiwack
On the compilation of Coq, we can see an increase of ~20% compile time on my completely non-scientific tests. Hopefully this can be fixed. There are a lot of low hanging fruits, but this is an iso-functionality commit. With a few exceptions which were not necessary for the compilation of the theories: - The declarative mode is not yet ported - The timeout tactical is currently deactivated because it needs some subtle I/O. The framework is ready to handle it, but I haven't done it yet. - For much the same reason, the ltac debugger is unplugged. It will be more difficult, but will eventually be back. A few comments: I occasionnally used a coercion from [unit Proofview.tactic] to the old [Prooftype.tactic]. It should work smoothely, but loses any backtracking information: the coerced tactics has at most one success. - It is used in autorewrite (it shouldn't be a problem there). Autorewrite's code is fairly old and tricky - It is used in eauto, mostly for "Hint Extern". It may be an issue as time goes as we might want to have various success in a "Hint Extern". But it would require a heavy port of eauto.ml4 - It is used in typeclass eauto, but with a little help from Matthieu, it should be easy to port the whole thing to the new tactic engine, actually simplifying the code. - It is used in fourier. I believe it to be inocuous. - It is used in firstorder and congruence. I think it's ok. Their code is somewhat intricate and I'm not sure they would be easy to actually port. - It is used heavily in Function. And honestly, I have no idea whether it can do harm or not. Updates: (11 June 2013) Pierre-Marie Pédrot contributed the rebase over his new stream based architecture for Ltac matching (r16533), which avoid painfully and expensively working around the exception-throwing control flow of the previous API. (11 October 2013) Rebasing over recent commits (somewhere in r16721-r16730) rendered a major bug in my implementation of Tacticals.New.tclREPEAT_MAIN apparent. It caused Field_theory.v to loop. The bug made rewrite !lemma, rewrite ?lemma and autorewrite incorrect (tclREPEAT_MAIN was essentially tclREPEAT, causing rewrites to be tried in the side-conditions of conditional rewrites as well). The new implementation makes Coq faster, but it is pretty much impossible to tell if it is significant at all. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16967 85f007b7-540e-0410-9357-904b9bb8a0f7

2013-08-23Fixing an incompleteness of the ring/field tacticsamahboub
The problem occurs when a customized ring/field structure declared with a so-called "morphism" (see 24.5 in the manual) tactic allowing to reify (numerical) constants efficiently. When declaring a ring/field structure, the user can provide a cast function phi in order to express numerical constants in another type than the carrier of the ring. This is useful for instance when the ring is abstract (like the type R of reals) and one needs to express constants to large to be parsed in unary representation (for instance using a phi : Z -> R). Formerly, the completeness of the tactic required (phi 1) (resp. (phi 0)) to be convertible to 1 (resp. 0), which is not the case when phi is opaque. This was not documented untill recently but I moreover think this is also not desirable since the user can have good reasons to work with such an opaque case phi. Hence this commit: - adds two constructors to PExpr and FExpr for a correct reification - unplugs the optimizations in reification: optimizing reification is much less efficient than using a cast known to the tactic. TODO : It would probably be worth declaring IZR as a cast in the ring/field tactics provided for Reals in the std lib. The completeness of the tactic formerly relied on the fact that git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16730 85f007b7-540e-0410-9357-904b9bb8a0f7
2013-05-05Little fix for Nsatz: hypotheses not directly relevant to the nsatzherbelin
problem are cleared (in case they denote applicative terms with at least 6 arguments). However some of them are used for type class instance inference (e.g. hypotheses of type Integral_domain).

2012-09-14The new ocaml compiler (4.00) has a lot of very cool warnings,regisgia
especially about unused definitions, unused opens and unused rec flags. The following patch uses information gathered using these warnings to clean Coq source tree. In this patch, I focused on warnings whose fix are very unlikely to introduce bugs. (a) "unused rec flags". They cannot change the semantics of the program but only allow the inliner to do a better job. (b) "unused type definitions". I only removed type definitions that were given to functors that do not require them. Some type definitions were used as documentation to obtain better error messages, but were not ascribed to any definition. I superficially mentioned them in one arbitrary chosen definition to remove the warning. This is unaesthetic but I did not find a better way. (c) "unused for loop index". The following idiom of imperative programming is used at several places: "for i = 1 to n do that_side_effect () done". I replaced "i" with "_i" to remove the warning... but, there is a combinator named "Util.repeat" that would only cost us a function call while improving readibility. Should'nt we use it? git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15797 85f007b7-540e-0410-9357-904b9bb8a0f7

2011-05-05Definitions of positive, N, Z moved in Numbers/BinNums.vletouzey
In the coming reorganisation, the name Z in BinInt will be a module containing all code and properties about binary integers. The inductive type Z hence cannot be at the same location. Same for N and positive. Apart for this naming constraint, it also have advantages : presenting the three types at once is clearer, and we will be able to refer to N in BinPos (for instance for output type of a predecessor function on positive). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14097 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
