- It's called `TopSet`, which corresponds with `SemiSet`.
- We now have a generic `SetUnfoldElemOf` for any `TopSet`.
- The `Hint Resolve coPset_top_subseteq : core` no longer works because the lemma is generic in a type class. AFAIK it is only used for `solve_ndisjoint`, so I added a specialized version to the `ndisj` hint database. We already have specialized versions of other set lemmas there.https://gitlab.mpi-sws.org/iris/stdpp/-/merge_requests/110Add decidability instances for Z.gt and Z.ge2020-02-13T21:16:07ZTej Chajedtchajed@gmail.comAdd decidability instances for Z.gt and Z.geUnfortunately these are not just defined as flipped versions of `Z.lt` and `Z.ge`.Unfortunately these are not just defined as flipped versions of `Z.lt` and `Z.ge`.https://gitlab.mpi-sws.org/iris/stdpp/-/merge_requests/108cogset2020-02-20T22:24:17ZDavid SwaseycogsetAdd a type `cogset A` of finite/cofinite sets of elements of countable type `A`.

When `A` is also infinite, all the usual operations are decidable. The implementation uses a pair of constructors (finite or infinite) each carrying a finite set.
The file includes efficient conversions to and from `gset A` (for finite cogsets) and to `coPset` (for arbitrary cogsets), as well as less efficient conversions to and from other finite sets and other sets with a top element.

`subset_of_set_seq` can be seen as a generalization of the existing `elem_of_set_seq`. It gives equations that one can extract from knowing that one `set_seq` is a subset of another `set_seq`.
The lemmas `subset_of_set_seq_len` and `elem_of_set_seq_len` are small variants of the same lemmas without the `_len` suffix. They extract information about the length or size of a `set_seq`.https://gitlab.mpi-sws.org/iris/stdpp/-/merge_requests/104Remove `:>>` subclass instance declarations2019-11-07T08:18:01ZRobbert KrebbersRemove `:>>` subclass instance declarationsThere are not documented in https://coq.inria.fr/refman/addendum/type-classes.html?highlight=class#coq:cmd.class, and they don't have any advantage, so it's better to stop using them.There are not documented in https://coq.inria.fr/refman/addendum/type-classes.html?highlight=class#coq:cmd.class, and they don't have any advantage, so it's better to stop using them.https://gitlab.mpi-sws.org/iris/stdpp/-/merge_requests/103Update gitignore for compatibility with Coq master2019-11-02T09:33:06ZTej Chajedtchajed@gmail.comUpdate gitignore for compatibility with Coq masterSee https://github.com/coq/coq/pull/10947 (.coqdeps.d now uses the name

- `filter P m ∪ filter (λ v, ¬ P v) m = m`
- `(∀ i, i ∈ X ↔ ∃ x, m !! i = Some x ∧ P (i, x)) → dom D (filter P m) ≡ X`
For the last one, I have repurposed the name `dom_map_filter`, which was previously used for `dom D (filter P m) ⊆ dom D m`. I have renamed the old lemma into `dom_map_filter_subseteq`. This follows current naming conventions.

a prefix, as done in VST for example.
This closes issue #42.
I have used the `sed` script below. This script took care of nearly all uses
apart from a few occurrences where a space was missing, e.g. `(,foo)`. In
this case, `coqc` will just fail, allowing one to patch up things manually.
The script is slightly too eager on Iris developments, where it also replaces
`($ ...)` introduction patterns. When porting Iris developments you thus may
want to remove the line for `$`.
