* Allow "|_=>_" in "match" in patterns, no more forced enumeration of constructorsGravatar letouzey2011-11-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For instance, consider this inductive type: Inductive Ind := A | B | C | D. For detecting "match" on this type, one was forced earlier to write code in Ltac using "match goal" and/or "context [...]" and long patterns such as: match _ with A => _ | B => _ | C => _ | D => _ end After this patch, this pattern can be shortened in many alternative ways: match _ with A => _ | _ => _ end match _ with B => _ | _ => _ end match _ in Ind with _ => _ end Indeed, if we want to detect a "match" of a given type, we can either leave at least one branch where a constructor is explicit, or use a "in" annotation. Now, we can also detect any "match" regardless of its type: match _ with _ => _ end Note : this will even detect "match" over empty inductive types. Compatibility should be preserved, since "match _ with end" will continue to correspond only to empty inductive types. Internally, the constr_pattern PCase has changed quite a lot, a few elements are now grouped into a case_info_pattern record, while branches are now lists of given sub-patterns. NB: writing "match" with missing last branches in a constr pattern was actually tolerated by Pattern.pattern_of_glob_constr earlier, since the number of constructor per inductive is unknown there. And this was triggering an uncaught exception in a array_fold_left_2 in Matching later. Oups. At least this patch fixes this issue... Btw: the code in Pattern.pattern_of_glob_constr was quadratic in the number of branch in a match pattern. I doubt this was really a problem, but having now linear code instead cannot harm ;-) git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14644 85f007b7-540e-0410-9357-904b9bb8a0f7
* Fixing incorrect change to pattern-unification over Meta's introducedGravatar herbelin2011-11-06
| | | | | | | | | | | | | | | in r14199 (June 2011). Meta's implicitly depend on the context they are defined in and this has to be taken into account for checking if occurrences are distinct (in particular, no Var's are allowed as arguments of a pattern-unifiable Meta). The example expected to be accepted thanks to r14199 is not a pattern-unification problem (it has more than one solution) and was anyway already accepted (strange). Compared to before r14199, aliases expansion and restriction of pattern unification check to variables occurring in the right-hand side are however now taken into account. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14642 85f007b7-540e-0410-9357-904b9bb8a0f7

We try to clarify the big boolean expression via "if", and for the moment we remove the detection of "nonlinearity" via duplicated_metas : on the example, some nonlinearity was found for strange reason (beta expansion ?), and after some discussion with Hugo, it is unclear whether this nonlinearity stuff is useful at all.
