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

2012-10-29Removed many calls to OCaml generic equality. This was done byppedrot
writing our own comparison functions, and enforcing monomorphization in many places. This should be more efficient, btw. Still a work in progress. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15932 85f007b7-540e-0410-9357-904b9bb8a0f7
2012-10-26Change Hint Resolve, Immediate to take a global reference as argumentmsozeau
instead of a general constr: this is the most common case and does not loose generality (one can simply define constrs before Hint Resolving them).

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

2012-03-26Module names and constant/inductive names are now in two separate namespacesletouzey
We now accept the following code: Definition E := 0. Module E. End E. Techically, we simply allow the same label to occur at most twice in a structure_body, which is a (label * structure_field_body) list). These two label occurences should not be at the same level of fields (e.g. a SFBmodule and a SFBmind are ok, but not two SFBmodule's or a SFBmodule and a SFBmodtype). Gain : a minimal amount of code change. Drawback : no more simple List.assoc or equivalent should be performed on a structure_body ... git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15088 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
2012-03-23Remove undocumented command "Delete foo"letouzey

2012-03-20Fixing alpha-conversion bug #2723 introduced in r12485-12486.herbelin
The optimisation done of Namegen.visibly_occur_id did not preserve the previous behavior when pr_constr/constr_extern/detype were called on a term with free rel variables. We backtrack on it to go back to the 8.2 behavior. Seized this opportunity to clarify the meaning of the at_top flag in constrextern.ml and printer.ml and to rename it into goal_concl_style. The badly-named at_top flag was introduced in Coq 6.3 in 1999 to mean that when printing variables bound in the goal, names had to avoid the names of the variables of the goal context, so as to keep naming stable when using "intro"; in r4458, printing improved by not avoiding names that were short names of global definitions, e.g. "S", or "O" (except when the at_top flag was on for compatibility reasons). Other printing strategies could be possible in the non-goal-concl-style mode. For instance, all bound variables could be made distinct in a given expression, even if no clash occur, therefore following so-called Barendregt's convention. This could be done by setting "avoid" to "ids_of_rel_context (rel_context env)" in extern_constr and extern_type (and then, Namegen.visibly_occur_id could be re-simplified again!). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15067 85f007b7-540e-0410-9357-904b9bb8a0f7
