* WARNING: unification changed (to fix a bug).Gravatar sacerdot2005-05-24
| | | | | | | | | | | | | | | | | 1. When matching ?i[sigma] against t' in some cases ?i was instantiated with t' ignoring the explicit substitution sigma (i.e. always doing mimick); however, when t' occurs in sigma ?i can be instatiated with a Var/Rel (i.e. doing projection). The new behaviour is not equivalent to the old one (even up to bugs) since the new behaviour may accept not well typed instantiations and fail only later whereas the old (but buggy) behaviour failed immediately. 2. Second bug fixed: it was the case that instantiating and evar doing projection did not check whether the body of the evar contained metavariables (that breaks a Coq invariant). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@7067 85f007b7-540e-0410-9357-904b9bb8a0f7

* HUGE COMMITGravatar sacerdot2005-01-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. when applying a functor F(X) := B to a module M, the obtained module is no longer B{X.t := M.t for all t}, but B{X.t := b where b is the body of t in M}. In principle it is now easy to fine tune the behaviour to choose whether b or M.t must be used. This change implies modifications both inside and outside the kernel. 2. for each object in the library it is now necessary to define the behaviour w.r.t. the substitution {X.t := b}. Notice that in many many cases the pre-existing behaviour w.r.t. the substitution {X.t := M.t} was broken (in the sense that it used to break several invariants). This commit fixes the behaviours for most of the objects, excluded a) coercions: a future commit should allow any term to be declared as a coercion; moreover the invariant that just a coercion path exists between two classes will be broken by the instantiation. b) global references when used as arguments of a few tactics/commands In all the other cases the behaviour implemented is the one that looks to me as the one expected by the user (if possible): [ terminology: not expanded (X.t := M.t) vs expanded (X.t := b) ] a) argument scopes: not expanded b) SYNTAXCONSTANT: expanded c) implicit arguments: not expanded d) coercions: expansion to be done (for now not expanded) e) concrete syntax tree for patterns: expanded f) concrete syntax tree for raw terms: expanded g) evaluable references (used by unfold, delta expansion, etc.): not expanded h) auto's hints: expanded when possible (i.e. when the expansion of the head of the pattern is rigid) i) realizers (for program extraction): nothing is done since the actual code does not look for the realizer of definitions with a body; however this solution is fragile. l) syntax and notation: expanded m) structures and canonical structures: an invariant says that no parameter can happear in them ==> the substitution always yelds the original term n) stuff related to V7 syntax: since this part of the code is doomed to disappear, I have made no effort to fix a reasonable semantics; not expanded is the default one applied o) RefArgTypes: to be understood. For now a warning is issued whether expanded != not expanded, and the not expanded solution is chosen. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@6555 85f007b7-540e-0410-9357-904b9bb8a0f7
