* Proper fix for complement/flip instances.Gravatar msozeau2011-10-10

* Improved handling of element equalities in fsetdec (fix #2467)Gravatar letouzey2011-10-07
| | | | | | | | | | | - We now handle things like (H : E.eq x x -> ...) by rewriting E.eq x x into True. - There was also a confusion between E.t and its various equivalent (but syntactically different) forms. This should be solved by preventing inlining during an inner functor application. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14520 85f007b7-540e-0410-9357-904b9bb8a0f7

* Omega: for non-arithmetical goals, try proving False from context (wish #2236)Gravatar letouzey2011-09-16
| | | | | | | | | | | | | | | | | | This way, no more error messages like "Unrecognized predicate". Some code simplification and reorganization on the way, in particular a few tests like "is_Prop ..." or "closed0 ..." were actually useless. Also add support for the situation H:~Zne x y for uniformity. Beware: scripts relying negatively on the strength of omega may have to be adapted (e.g. "try omega. some_more_tactics_in_case_omega_fails."). For instance, one line deletion in PermutSetoid.v Probably more cumbersome : "auto with *" becomes stronger since it may call omega. Todo : check the impact on contribs tomorrow. Btw, this commit seems to solve a bug where omega was to be guided by some (set foo:= ...) before being able to succeed (cf PermutSetoid.v) git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14474 85f007b7-540e-0410-9357-904b9bb8a0f7

* SearchAbout and similar: add a customizable blacklistGravatar letouzey2011-08-11
| | | | | | | | | | | | | | | | | | | | | | | | Instead of hard-coding in search.ml some substrings such as "_admitted" or "_subproof" we don't want to see in results of SearchAbout and co, we now have a user command: Add Search Blacklist "foo". Remove Search Blacklist "foo". (* the opposite *) Print Table Search Blacklist. (* the current state *) In Prelude.v, three substrings are blacklisted originally: - "_admitted" for internal lemmas due to admit. - "_subproof" for internal lemmas due to abstract. - "Private_" for hiding auxiliary modules not meant for global usage. Note that substrings are searched in the fully qualified names of the available lemmas (e.g. "Coq.Init.Peano.plus"). This commit also adds the prefix "Private_" to some internal modules in Numbers, Z, N, etc. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14408 85f007b7-540e-0410-9357-904b9bb8a0f7

* Less ambitious application of a notation for eq_rect. We proposedGravatar herbelin2011-08-10
| | | | | | | | | | | | | | | | | | "rewrite Heq in H" but "rewrite" is sometimes used by users and I don't want to have to change their file. The solution to put the notations in a module does not work with name "rewrite" because loading the module would change the status of "rewrite" from simple ident to keyword (and we cannot declare "rewrite" as an ident, as shown in previous commit). Then we come back on notation "rew" (this name is also used by some users), in a module. This continues commit r14366 and r14390 and improves on the level of the notation. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14400 85f007b7-540e-0410-9357-904b9bb8a0f7

* Cleanup of files related with power over Z.Gravatar letouzey2011-07-01
| | | | | | | | | | | | | | - Zpow_def, Zpower, Zpow_facts shortened thanks to stuff in BinInt.Z - The alternative Zpower_alt is now in a separate file Zpow_alt.v, not loaded by default. - Some more injection lemmas in Znat (pow, div, mod, quot, rem) - Btw, added a "square" function in Z, N, Pos, ... (instead of Zpow_facts.Zsquare). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14253 85f007b7-540e-0410-9357-904b9bb8a0f7

| | | | | | | | | Note that in NSig (and hence NMake and BigN), to_N is now Z.to_N (to_Z ...) instead of Z.abs_N (to_Z ...).

* Clean-up of Znumtheory, deletion of Zgcd_defGravatar letouzey2011-06-24
| | | | | | | | | | | In particular, we merge the old Zdivide (used to be an ad-hoc inductive predicate) and the new Z.divide (based on exists). Notations allow to do that (almost) transparently, the only impact is that the name picked by the system will not be "q" anymore when destructing a Z.divide. Some fragile scripts may have to be fixed. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14239 85f007b7-540e-0410-9357-904b9bb8a0f7
