* Tentative to make unification check types at every instanciation of anGravatar msozeau2011-03-11
| | | | | | | | | | | | | evar, and simultaneously make type inference with universes work better. This only exports more functions from kernel/univ, to be able to work with a set of universe variables during type inference. Universe constraints are gradually added during type checking, adding information necessary e.g. to lower the level of unknown Type variables to Prop or Set. There does not seem to be a disastrous performance hit on the stdlib, but might have one on some contribs (hence the "Tentative"). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13905 85f007b7-540e-0410-9357-904b9bb8a0f7

* A new command "Separate Extraction"Gravatar letouzey2011-03-07
| | | | | | | | | | | | | | | This is a mix of "Recursive Extraction" and "Extraction Library": - like "Extraction Library", the extracted code is splitted in separated files, one per coq source file. - unlike "Extraction Library", but similarly to "Recursive Extraction", not everything gets extracted, but only dependencies of some initially-given elements We prepare for a more clever dependency selection inside sub-modules. For the moment all needed sub-modules are still fully extracted (other we would need to fix signatures accordingly). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13888 85f007b7-540e-0410-9357-904b9bb8a0f7

* Extraction: improved indentation of extracted code (fix #2497)Gravatar letouzey2011-03-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For Haskell, we still try to provide readable indentation, but we now avoid relying on this indentation for correctness. Instead, we use layout-independant syntax with { } when necessary (after "case of" and "let"). It is much safer this way, even if the syntax gets a bit more cumbersome. For people allergic to {;}, they can most of the time do a tr -d "{;}" without changing the meaning of the program. Be careful nonetheless: since "case of" is now delimited, some parenthesis that used to be mandatory are now removed. Note also that the initial "module ... where" is still without { }: even when Format goes crazy it doesn't tamper with column 0. Other modifications: - Using "Set Printing Width" now affects uniformly the extraction pretty-printers. You can set a greater value than the default 78 before extracting a program that you know to be "really deep". - In ocaml (and also a bit in Haskell), we now try to avoid abusing of 2-char-right-indentation. For instance | is now aligned with the "m" of match. This way, max_indent will be reached less frequently. - As soon as a pretty-print box contains an explicit newline, we set its virtual size to a big number, in order to prevent this box to be part of some horizontal arrangement. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13870 85f007b7-540e-0410-9357-904b9bb8a0f7

* A fine-grain control of inlining at functor application via priority levelsGravatar letouzey2011-01-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As said in CHANGES: << The inlining done during application of functors can now be controlled more precisely. In addition to the "!F G" syntax preventing any inlining, we can now use a priority level to select parameters to inline : "<30>F G" means "only inline in F the parameters whose levels are <= 30". The level of a parameter can be fixed by "Parameter Inline(30) foo". When levels aren't given, the default value is 100. One can also use the flag "Set Inline Level ..." to set a level. >> Nota : the syntax "Parameter Inline(30) foo" is equivalent to "Set Inline Level 30. Parameter Inline foo.", and "Include <30>F G" is equivalent to "Set Inline Level 30. Include F G." For instance, in ZBinary, eq is @Logic.eq and should rather be inlined, while in BigZ, eq is (fun x y => [x]=[y]) and should rather not be inlined. We could achieve this behavior by setting a level such as 30 to the parameter eq, and then tweaking the current level when applying functors. This idea of levels might be too restrictive, we'll see, but at least the implementation of this change was quite simple. There might be situation where parameters cannot be linearly ordered according to their "inlinablility". For these cases, we would need to mention names to inline or not at a functor application, and this is a bit more tricky (and might be a pain to use if there are many names). No documentation for the moment, since this feature is experimental and might still evolve. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13807 85f007b7-540e-0410-9357-904b9bb8a0f7
* Remove the "Boxed" syntaxes and the const_entry_boxed fieldGravatar letouzey2011-01-28
| | | | | | | | | | | | | | | | According to B. Gregoire, this stuff is obsolete. Fine control on when to launch the VM in conversion problems is now provided by VMcast. We were already almost never boxing definitions anymore in stdlib files. "(Un)Boxed Definition foo" will now trigger a parsing error, same with Fixpoint. The option "(Un)Set Boxed Definitions" aren't there anymore, but tolerated (as no-ops), since unknown options raise a warning instead of an error by default. Some more cleaning could be done in the vm. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13806 85f007b7-540e-0410-9357-904b9bb8a0f7

* ARGUMENT EXTEND: forbid TYPED simultaneously with {RAW,GLOB}_TYPEDGravatar glondu2010-12-25
| | | | | | | | | | | | Rationale: the expansion ignores the TYPED clause when {RAW,GLOB}_TYPED are given. Indeed, in this case, the final type is a consequence of either "INTERPRETED BY" (if given), or the default one based on GLOB_TYPED. This avoids the pitfall of the "raw" argument extension, where the TYPED clause was unused and totally misleading. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13760 85f007b7-540e-0410-9357-904b9bb8a0f7

* Change of nomenclature: rawconstr -> glob_constrGravatar glondu2010-12-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | There was a discrepancy of the notions "raw" and "globalized" between constrs and tactics, and some confusion of the notions in e.g. genarg.mli (see all globwit_* there). This commit is a first step towards unification of terminology between constrs and tactics. Changes in module names will be done separately. In extraargs.ml4, the "ARGUMENT EXTEND raw" and related stuff, even affected by this change, has not been touched and highlights another confusion in "ARGUMENT EXTEND" in general that will be addressed later. The funind plugin doesn't respect the same naming conventions as the rest, so leave some "raw" there for now... they will be addressed later.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Integer division: quot and rem (trunc convention) in addition to div and modGravatar letouzey2010-11-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (floor convention). We follow Haskell naming convention: quot and rem are for Round-Toward-Zero (a.k.a Trunc, what Ocaml, C, Asm do by default, cf. the ex-ZOdiv file), while div and mod are for Round-Toward-Bottom (a.k.a Floor, what Coq does historically in Zdiv). We use unicode รท for quot, and infix rem for rem (which is actually remainder in full). This way, both conventions can be used at the same time. Definitions (and proofs of specifications) for div mod quot rem are migrated in a new file Zdiv_def. Ex-ZOdiv file is now Zquot. With this new organisation, no need for functor application in Zdiv and Zquot. On the abstract side, ZAxiomsSig now provides div mod quot rem. Zproperties now contains properties of them. In NZDiv, we stop splitting specifications in Common vs. Specific parts. Instead, the NZ specification is be extended later, even if this leads to a useless mod_bound_pos, subsumed by more precise axioms. A few results in ZDivTrunc and ZDivFloor are improved (sgn stuff). A few proofs in Nnat, Znat, Zabs are reworked (no more dependency to Zmin, Zmax). A lcm (least common multiple) is derived abstractly from gcd and division (and hence available for nat N BigN Z BigZ :-). In these new files NLcm and ZLcm, we also provide some combined properties of div mod quot rem gcd. We also provide a new file Zeuclid implementing a third division convention, where the remainder is always positive. This file instanciate the abstract one ZDivEucl. Operation names are ZEuclid.div and ZEuclid.modulo. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13633 85f007b7-540e-0410-9357-904b9bb8a0f7
