2018-05-04[api] Rename `global_reference` to `GlobRef.t` to follow kernel style.Emilio Jesus Gallego Arias
In #6092, `global_reference` was moved to `kernel`. It makes sense to go further and use the current kernel style for names. This has a good effect on the dependency graph, as some core modules don't depend on library anymore. A question about providing equality for the GloRef module remains, as there are two different notions of equality for constants. In that sense, `KerPair` seems suspicious and at some point it should be looked at.

2015-12-15Extraction: replace unused variable names by _ in funs and matchs (fix #2842)Pierre Letouzey
This is done via a unique pass which seems roughly linear in practice, even on big developments like CompCert. There's a List.nth in an env at each MLrel, that could be made logarithmic if necessary via Okasaki's skew list for instance. Another approach would be to keep names (as a form of documentation), but prefix them by _ to please OCaml's warnings. For now, let's be radical and use the _ pattern.
2015-12-12Extraction: nicer implementation of ImplicitsPierre Letouzey
Instead of the original hacks (embedding implicits in string msg in MLexn !) we now use a proper construction MLdummy (Kimplicit (r,i)) to replace the use of the i-th argument of constant or constructor r when this argument has been declared as implicit. A new option Set/Unset Extraction SafeImplicits controls what happens when some implicits still occur after an extraction : fail in safe mode, or otherwise produce some code nonetheless. This code is probably buggish if the implicits are actually used to do anything relevant (match, function call, etc), but it might also be fine if the implicits are just passed along. And anyway, this unsafe mode could help figure what's going on. Note: the MLdummy now expected a kill_reason, just as Tdummy. These kill_reason are now Ktype, Kprop (formerly Kother) and Kimplicit. Some minor refactoring on the fly.

2014-03-05Remove many superfluous 'open' indicated by ocamlc -w +33Pierre Letouzey
With ocaml 4.01, the 'unused open' warning also checks the mli :-) Beware: some open are reported as useless when compiling with camlp5, but are necessary for compatibility with camlp4. These open are now marked with a comment.

2011-11-28Extraction: Richer patterns in matchs as proposed by P.N. Tollitteletouzey
The MLcase has notably changed: - No more case_info in it, but only a type annotation - No more "one branch for one constructor", but rather a sequence of patterns. Earlier "full" pattern correspond to pattern Pusual. Patterns Pwild and Prel allow to encode optimized matchs without hacks as earlier. Other pattern situations aren't used (yet) by extraction, but only by P.N Tollitte's code. A MLtuple constructor has been introduced. It isn't used by the extraction for the moment, but only but P.N. Tollitte's code. Many pretty-print functions in ocaml.ml and other have been reorganized git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14734 85f007b7-540e-0410-9357-904b9bb8a0f7
2010-12-21Extraction: avoid type-unsafe optimisation of pattern-matchings (fix #2413)letouzey
We now keep some type information in the "info" field of constructors and cases, and compact a match with some default branches (or remove this match completely) only if this transformation is type-preserving. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13732 85f007b7-540e-0410-9357-904b9bb8a0f7

2010-09-17Extraction: multiple fixes related with the Not_found encountered by X. Leroyletouzey
Cf. coqdev for the details of the bug report. - Protect some Hashtbl.find and other risky functions in order to avoid as much as possible to end with an irritating Anomaly : Not_found. - Re-enable in pp_ocaml_extern the case of a module-file used as a module (e.g. module A' := A for A.v) when doing modular extraction. - Rework the code that decides to "open" or not modules initially: opening A when A contains a submodule B hides the file B even when B isn't opened itself, we avoid that now. - Fix some tables (sets or maps) used by extraction for which it is critical to consider constants/inductives/global_reference _not_ modulo the equivalence of Elie, but rather via Pervasives.compare. Still to do : avoid appearance of '_a in extracted code. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13424 85f007b7-540e-0410-9357-904b9bb8a0f7

2010-07-08Extraction: more factorization of common match branchesletouzey
In addition to the "| _ -> cst" situation, now we can also reconstruct a "| e -> f e" final branch. For instance, this has a tremenduous effect on Compcert/backend/Selection.v. NB: The "fun" factorisation is almost more general than the "cst" situation, but not always. Think of A=>A|B=>A, 1st branch will be recognized as (fun x->x), not (fun x->A). We also add a fine detection of inductive types with phantom type variables, for which this optimisation is type-unsafe. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13267 85f007b7-540e-0410-9357-904b9bb8a0f7

2010-04-30Extraction: an experimental command to get rid of some cst/constructor argumentsletouzey
The command : Extraction Implicit foo [1 3]. will tell the extraction to consider fst and third arg of foo as implicit, and remove them, unless a final occur-check after extraction shows they are still there. Here, foo can be a inductive constructor or a global constant. This allow typicaly to extract vectors into usual list :-) git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12982 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
2010-04-16Extraction: less eta in calls to global functions, better optimization phaseletouzey
- we saturate the normalize function : as long as (kill_dummy + simpl) isn't a nop, we do it again. - generalize_case allowed on all types of theories/Init/*.v instead of only bool,sumbool,sumor. NB: this optim cannot be performed on any type, it might produce untyped code. - common_branch allowed on match with one branch: in this situation it indicates whether the match can be removed or not. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12942 85f007b7-540e-0410-9357-904b9bb8a0f7
2010-04-16Extraction: ad-hoc identifier type with annotations for reductionsletouzey
* An inductive constructor Dummy instead of a constant dummy_name * The Tmp constructor indicates that the corresponding MLlam or MLletin is extraction-specific and can be reduced if possible * When inlining a glob (for instance a recursor), we tag some lambdas as reducible. In (nat_rect Fo Fs n), the head lams of Fo and Fs are treated this way, in order for the recursive call inside nat_rect to be correctly pushed as deeper as possible. * This way, we can stop allowing by default linear beta/let reduction even under binders (can be activated back via Set Extraction Flag). * Btw, fix the strange definition of non_stricts for (x y). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12938 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-10-21This big commit addresses two problems:soubiran
1- Management of the name-space in a modular development / sharing of non-logical objects. 2- Performance of atomic module operations (adding a module to the environment, subtyping ...). 1- There are 3 module constructions which derive equalities on fields from a module to another: Let P be a module path and foo a field of P Module M := P. Module M. Include P. ... End M. Declare Module K : S with Module M := P. In this 3 cases we don't want to be bothered by the duplication of names. Of course, M.foo delta reduce to P.foo but many non-logical features of coq do not work modulo conversion (they use eq_constr or constr_pat object). To engender a transparent name-space (ie using P.foo or M.foo is the same thing) we quotient the name-space by the equivalence relation on names induced by the 3 constructions above. To implement this, the types constant and mutual_inductive are now couples of kernel_names. The first projection correspond to the name used by the user and the second projection to the canonical name, for example the internal name of M.foo is (M.foo,P.foo). So: ************************************************************************************* * Use the eq_(con,mind,constructor,gr,egr...) function and not = on names values * ************************************************************************************* Map and Set indexed on names are ordered on user name for the kernel side and on canonical name outside. Thus we have sharing of notation, hints... for free (also for a posteriori declaration of them, ex: a notation on M.foo will be avaible on P.foo). If you want to use this, use the appropriate compare function defined in name.ml or libnames.ml. 2- No more time explosion (i hoppe) when using modules i have re-implemented atomic module operations so that they are all linear in the size of the module. We also have no more unique identifier (internal module names) for modules, it is now based on a section_path like mechanism => we have less substitutions to perform at require, module closing and subtyping but we pre-compute more information hence if we instanciate several functors then we have bigger vo. Last thing, the checker will not work well on vo(s) that contains one of the 3 constructions above, i will work on it soon... git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12406 85f007b7-540e-0410-9357-904b9bb8a0f7
