2011-06-18Relaxed the constraint introduced in r14190 that froze the existingherbelin
evars when rewriting. Use it for autorewrite and subst. Accept evars instantiation in multi_rewrite so that rewrite alone remains compatible (it is used in contribs, e.g. Godel, in places where it does not seem absurd to allow it), but there are no good reason for it. Comments welcome. + addition of some tests for rewriting (one being related to commit 14217) git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14222 85f007b7-540e-0410-9357-904b9bb8a0f7

2010-06-13Fixing bug 2300 (ltac pattern-matching returning terms with concrete universes).herbelin
By the way, there is an open problem of which conversion to use (conv, evarconv, with or w/o universes levels) when trying to unify multiple instances of the same variable in ltac pattern-matching. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13130 85f007b7-540e-0410-9357-904b9bb8a0f7
2010-06-13Addressed bug #2320 in v8.2 and v8.3 branches ("refine" problem withherbelin
metas in return predicate of "match"); propagated protection for #2310 ("refine" problem with dependent metas of higher-order type) in v8.3 to v8.2. Everything goes well in trunk thanks for the new proof engine. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13129 85f007b7-540e-0410-9357-904b9bb8a0f7
2010-06-13Addressed bug #2310 and replaced anomaly "unknown meta" raised by "refine"herbelin
by a regular error in v8.3. Example behaves better in trunk thanks to new proof engine. In fact, there are two distinct solutions to a unification problem: should "refine" commit to one of them or leave the problem open? For trunk, improved the unification error message by enforcing nf_evar (but at some time, nf_evar in error messages should move to himsg because it is costly when errors are used for backtracking). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13127 85f007b7-540e-0410-9357-904b9bb8a0f7
2010-06-12Fixed bug #2135 (second-order unification was raising cryptic message)herbelin
- made the example work (a call to whd_meta was missing) - replaced the internal error messages of w_unify_to_subterm_list into user-understandable messages - incidentally fixed the meaning of whd_meta (which now takes an evd) and meta_name (which now does what it means and do not treat differently the instantiated metas) git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13122 85f007b7-540e-0410-9357-904b9bb8a0f7
