* Better comparison functions in OrderedTypeExGravatar letouzey2009-07-22
| | | | | | | | | | | | | | | The compare functions are still functions-by-tactics, but now their computational parts are completely pure (no use of lt_eq_lt_dec in nat_compare anymore), while their proofs parts are simply calls to (opaque) lemmas. This seem to improve the efficiency of sets/maps, as mentionned by T. Braibant, D. Pous and S. Lescuyer. The earlier version of nat_compare is now called nat_compare_alt, there is a proof of equivalence named nat_compare_equiv. By the way, various improvements of proofs, in particular in Pnat. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12247 85f007b7-540e-0410-9357-904b9bb8a0f7

* Many fixes in unification:Gravatar msozeau2009-05-20
| | | | | | | | | | | | | | | | | - Restore failure when types don't unify in [unify_types] (undoing r12075) but try to be more clever about cumulativity using the meta's [instance_status] information. - Fix second-order abstraction when K is not allowed to ensure that we don't unify twice with the same subterm in [w_unify_to_subterm_list]. A more elaborate solution would be give the list to [w_unify_to_subterm] so that it keeps going when it finds an already-found instantiation. - Two "obvious" errors fixed: taking the wrong instance status when unifying with a meta on the right and forgoting type equations in [w_merge]. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12136 85f007b7-540e-0410-9357-904b9bb8a0f7

| | | | | | | | | | | | | | | strategies (à la ELAN). Now setoid_rewrite is just one strategy and autorewrite is a more elaborate one. Any kind of traversals can be defined, strategies can be composed etc... in ML. An incomplete (no fix) language extension for specifying them in Ltac is there too.

* Rewrite of Program Fixpoint to overcome the previous limitations: Gravatar msozeau2009-03-28
| | | | | | | | | | | | | | | - The measure can now refer to all the formal arguments - The recursive calls can make all the arguments vary as well - Generalized to any relation and measure (new syntax {measure m on R}) This relies on an automatic curryfication transformation, the real fixpoint combinator is working on a sigma type of the arguments. Reduces to the previous impl in case only one argument is involved. The patch also introduces a new flag on implicit arguments that says if the argument has to be infered (default) or can be turned into a subgoal/obligation. Comes with a test-suite file. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12030 85f007b7-540e-0410-9357-904b9bb8a0f7

* Parsing files for numerals (+ ascii/string) moved into pluginsGravatar letouzey2009-03-27
| | | | | | | | | | | | | | Idea: make coqtop more independant of the standard library. In the future, we can imagine loading the syntax for numerals right after their definition. For the moment, it is easier to stay lazy and load the syntax plugins slightly before the definitions. After this commit, the main (sole ?) references to theories/ from the core ml files are in Coqlib (but many parts of coqlib are only used by plugins), and it mainly concerns Init (+ Logic/JMeq and maybe a few others). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12024 85f007b7-540e-0410-9357-904b9bb8a0f7

* Better mechanism for loading initial pluginsGravatar letouzey2009-03-14
| | | | | | | | | | | | | | | | Instead of dirty hacks in toplevel/coqtop.ml, we simply add some Declare ML Module in Prelude.v. Gain: now that coqdep is clever enough, dependencies are automatic, and we can simplify the Makefile quite a lot: no more references to INITPLUGINSBEST and the like. Besides, mltop.ml4 can also be simplified a lot: by giving $(CONTRIBSTATIC) to coqmktop instead of contrib.cma, now coqtop is aware that it already contain the static plugins (or not), and subsequent ML Module are ignored correctly without us having to do anything :-) git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11979 85f007b7-540e-0410-9357-904b9bb8a0f7
