* Big reorganization of romega/ReflOmegaCore.v: towards a modular Gravatar letouzey2007-07-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | and generic romega tactic... For the moment, nothing is visible yet from the user's point of view (hopefully). But internally, we prepare a romega that can works on any integer types. ReflOmegaCore is now separated in several modules: * First, an interface Int that specifies the minimal amount of things needed on our integer type for romega to work: - int should be a ring (re-use of ring_theory definition ;-) - it should come with an total order, compatible with + * - - we should have a decidable ternary comparison function - moreover, we ask one (and only one!) critical property specific to integers: a<b <-> a<=b-1 * Then a functor IntProperties derives from this interface all the various lemmas on integers that are used in the romega part, in particular the famous OMEGA?? lemmas. * The romega reflexive part is now in another functor IntOmega, that rely on some Int: no more Z inside. The main changes is that Z0 was a constructor whereas our abstract zero isn't. So matching Z0 is transformed into (if beq ... 0 then ...). With extensive use of && and if then else, it's almost clearer this way. * Finally, for the moment Z_as_Int show that Z fulfills our interface, and ZOmega = IntOmega(Z_as_Int) is used by the tactic. Remains to be done: - revision of the refl_omega to use any Int instead of just Z, and creating a user interface. - Int has no particular reason to use the leibniz equality (only rely on the beq boolean test). Setoids someday ? - a version with "semi-ring" for nat ? or rather a generic way to plug additional equations on the fly, e.g. n>=0 for every nat subpart ? git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@9966 85f007b7-540e-0410-9357-904b9bb8a0f7
* Improvements / Bug fixes for ROmega Gravatar letouzey2007-07-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ----------------------------------- All romega tests in the test-suite are now bug-free. The only known remaining limitation of romega with respect to omega is that it cannot handle stuff on nat. * Equivalences A<->B are now understood by romega (as well as omega), and seen as (A->B)/\(B->A). There might be a smarter way to procede, for instance having a primitive Iff construct and trying to break equivalences as late as possible. * Conclusion-as-Pprop issue: After the resolution by the abstract omega machinery, useless parts are discarded from the reification process by replacing them with Pprop construct (see really_useful_prop). This allow to decrease the size of the proof terms and speed up their normalisation, I guess. But when such Pprop are created in the conclusion, this leads to failure, since concl is negated, and this is donc only if it is decidable. And introducing some Pprop might change the decidability status of the concl: for instance, Pfalse is decidable, whereas Pprop False is considered as _not_ decidable. Quick fix: no more really_useful_prop applied on concl (needs careful computation of useful_var). * NEGATE_CONTRADICT(_INV): This trace instrution comes in fact in two flavors, according to a boolean flag. We now translate to O_NEGATE_CONTRADICT_INV if this flag is false. (fix Besson's bug #1298) * EXACT_DIVIDE: could be used on NeqTerm and not only on EqTerm. * h_step indexes: The abstract omega machinery can introduce new hyps. In the list of hyps, they appears _before_ the regular one (but after the goal seen as an hyp by negating it). But the normalization steps were applied to regular hyps thanks to their indexes counted _before_ the addition extra hyps. * extra hyps (a)normal forms: extra hyps and variables are initially of the shape poly(v1,...,v(n-1)) = vn but O_STATE was expecting them in form 0 = poly(...) + -vn (by the way, SPLIT_INEQ should be checked someday). Since the above is one weekend's worth of debugging, there might well remain some more bugs :-(. For the record, here's the less painful way to debug a failed romega run: - activate debug flag in omega.ml and refl_omega.ml - at the bottom of refl_omega, replace normalise_vm_in_concl with convert_no_check (see comment there): this allow to skip the usually _huge_ error message about "Impossible to unify True with ..." - run the romega - try to run Qed, and enjoy the nice errror message about a (omega_tactic ? ? ? ?) that should be reducible to True. Here starts the real debug work... git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@9962 85f007b7-540e-0410-9357-904b9bb8a0f7

| | | | | | | | | | | | | | | | | | | | | | rewrite H, H' means: rewrite H; rewrite H'. This should still be compatible with other "features" of rewrite: like orientation, implicit arguments (t:=...), and "in" clause. Concerning the "in" clause, for the moment only one is allowed at the very end of the tactic, and it applies to all the different rewrites that are done. For instance, if someone _really_ wants to use all features at the same time: rewrite H1 with (t:=u), <-H2, H3 in * means: rewrite H1 with (t:=u) in *; rewrite <- H2 in *; rewrite H3 in * git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@9954 85f007b7-540e-0410-9357-904b9bb8a0f7
