2012-11-08Monomorphized a lot of equalities over OCaml integers, thanks toppedrot
the new Int module. Only the most obvious were removed, so there are a lot more in the wild. This may sound heavyweight, but it has two advantages: 1. Monomorphization is explicit, hence we do not miss particular optimizations of equality when doing it carelessly with the generic equality. 2. When we have removed all the generic equalities on integers, we will be able to write something like "let (=) = ()" to retrieve all its other uses (mostly faulty) spread throughout the code, statically. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15957 85f007b7-540e-0410-9357-904b9bb8a0f7

2012-09-14Moving Utils.list_* to a proper CList module, which includes stdlibppedrot

That way, an "open Util" in the header permits using any function of CList in the List namespace (and in particular, this permits optimized reimplementations of the List functions, as, for example, tail-rec implementations. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15801 85f007b7-540e-0410-9357-904b9bb8a0f7
2012-09-14This patch removes unused "open" (automatically generated fromregisgia
compiler warnings). I was afraid that such a brutal refactoring breaks some obscure invariant about linking order and side-effects but the standard library still compiles. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15800 85f007b7-540e-0410-9357-904b9bb8a0f7
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

2012-07-11Severe reorganisation of the code of tactics in Proofview.aspiwack
All the purely monadic code has been moved to a new module Monads, where, I'm afraid to confess, I got to use a number of proof transformers to modularise the definition of tactics. It is still not easy to understand (why would it with backtracking support?) but at least it's more robust, cleaner, and more extensible. Plus there is now a Proofview.tclORELSE which will be used to interprete the Ltac tactical (t1 || t2). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15596 85f007b7-540e-0410-9357-904b9bb8a0f7

2012-03-30info_trivial, info_auto, info_eauto, and debug (trivial|auto)letouzey
To mitigate the lack of a general "info" tactical, let's introduce some specialized tactics info_trivial, info_auto and info_eauto that display the basic tactics used when solving a goal. We also add tactics "debug trivial" and "debug auto" which display every basic tactics attempted by trivial or auto. Triggering the "info" or "debug" mode for auto, eauto, trivial can also be done now via global options, such as Set Debug Auto or Set Info Eauto. In case both debug and info modes are activated, the debug mode takes precedence. NB: it would be nice to name these tactics "info xxx" instead of "info_xxx", but I don't see how to implement a "info eauto" in eauto.ml4 (hence by TACTIC EXTEND) while keeping a generic "info foo" tactic in g_ltac.ml4 (useful to display a nice message about the unavailability of the general info). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15103 85f007b7-540e-0410-9357-904b9bb8a0f7

2012-03-23A unified backtrack mechanism, with a basic "Show Script" as side-effectletouzey
Migrate the backtracking code from ide_slave.ml into a new backtrack.ml. In particular the history stack of commands that used to be there is now non-coqide-specific. ** Adapted commands ** - "Show Script": a basic functional version is restored (and the printing of scripts at Qed in coqtop). No indentation, one Coq command per line, based on the vernac_expr asts recorded in the history stack, printed via Ppvernac. - "Back n" : now mimics the backtrack of coqide: it goes n steps back (both commands and proofs), and maybe more if needed to avoid re-entering a proof (it outputs a warning in this case). - "BackTo n" : still try to go back to state n, but it also handles the proof state, and it may end on some state n' <= n if needed to avoid re-entering a proof. Ideally, it could someday be used by ProofGeneral instead of the complex Backtrack command. ** Compatible commands ** - "Backtrack" is left intact from compatibility with current ProofGeneral. We simply re-synchronize the command history stack after each Backtrack. - "Undo" is kept as a standard command, not a backtracking one, a bit like "Focus". Same for "Restart" and "Abort". All of these are now accepted in coqide (Undo simply triggers a warning). - Undocumented command "Undo To n" (counting from start of proof instead of from end) also keep its semantics, it is simply made compatible with the new stack mechanism. ** New restrictions ** We now forbid backtracking commands (Reset* / Back*) inside files when Load'ing or compiling, or inside VernacList/VernacTime/VernacFail. Too much work dealing with these situation that nobody uses. ** Internal details ** Internally, the command stack differs a bit from what was in Ide_slave earlier (which was inspired by lisp code in ProofGeneral). We now tag commands that are unreachable by a backtrack, due to some proof being finished, aborted, restarted, or partly Undo'ed. This induce a bit of bookkeeping during Qed/Abort/Restart/Undo, but then the backtracking code is straightforward: we simply search backward the first reachable state starting from the desired place. We don't depend anymore on the proof names (apart in the last proof block), It's more robust this way (think of re-entering a M.foo from an outside proof foo). Many internal clarifications in Lib, Vernac, etc. For instance "Reset Initial" is now just a BackTo 1, while "Reset foo" now calls (Lib.label_before_name "foo"), and performs a BackTo to the corresponding label. Concerning Coqide, we directly suppress the regular printing of goals via a flag in Vernacentries. This avoid relying on a classification of commands in Ide_slave as earlier. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15085 85f007b7-540e-0410-9357-904b9bb8a0f7
