13 years agoMajor speed-up:
Claudio Sacerdoti Coen [Mon, 6 Jun 2011 16:41:34 +0000 (16:41 +0000)]
Major speed-up:

 1) bug fixed: the fo_unif applied to a metavariable in the subst made a
    recursive call using unify. Thus, in case of failure of the unify
    (after hints, reduction, etc.), fo_unif failed and hints, reduction,
    etc. was tried again. This resulted in an exponential blow-up in the
    worst case.
 2) bug fixed: in the case  ? args == ?pattern, the ?pattern was delifted
    w.r.t. args, but during the delift the special unification case with
    a pattern was considered again. This was costly since reduction was
    used on the first argument of the unification.
 3) semantics of fo_unif "fixed": it is now succesfull on every pair of
    terms whose rigid prefix is equal and whose arguments are unifiable.
    Before it used to fail for example on (x args == x args) where x is
    a Rel.
 4) BEHAVIOUR OF DELIFT CHANGED: it no longer matches terms in the local
    context up to full unification, but only up to fo_unif. Some tactics
    that used to be accepted could now fail and the user needs to change
    the terms by hand before applying the tactic. On the other hand, the
    speed up is really significant.

Delift used to produce not well typed substitutions. In turn, this
led to tactics that were not failing immediately, but only at Qed.

Fixed by adding the appropriate check to the delift function.

Note:
 - pass the metavariable number (-1) to avoid the check when you know what
   you are doing (e.g. when delift is just used to restrict a term or to
   replace a term with a convertible one). This used to be 0 (not -1).
 - in some cases (algebraic universes and implicits used to stop chains of
   metavariables) the check is relaxed
 - to make the CerCo script pass (in very "reasonable" and "frequent" cases),
   the algorithm needs to solve the following unification problem:
     S (?[n]) == ?[(S n)]
   Our algorithm used to delift S(?[n]) w.r.t. (S n), yielding x |- ? := x.
   By chance, this was the right solution since S (?[n]) becomes (S n) and
   also ?[(S n)] becomes (S n). However, the two solutions were both added
   to the subst (first bug) and they could even be different (second bug).
   We fix this by checking that they are not different.
   However, at the moment, the solution still occurs twice in the subst....
