Arrays are fixed-size and provide safe and unsafe functions to access their elements.
Vectors can grow in size and use the unsafe array methods to access their elements.
Safety is ensured by branding vectors, meaning each vector is tagged with a
fresh type variable. Statically, this has a similar effect as existential types.
Semantically, the type variable is used to encode an ADT, i.e. impose invariants on the vector.Ralf Jungjung@mpi-sws.orgRalf Jungjung@mpi-sws.orghttps://gitlab.rts.mpi-sws.org/iris/examples/-/merge_requests/19Fix and conditional increment example2019-06-04T15:45:49ZRodolphe LepigreFix and conditional increment examplehttps://gitlab.rts.mpi-sws.org/iris/examples/-/merge_requests/18Some [positive] was sometimes used for [loc], which is now abstract.2019-05-31T16:56:47ZRodolphe LepigreSome [positive] was sometimes used for [loc], which is now abstract.https://gitlab.rts.mpi-sws.org/iris/examples/-/merge_requests/17Bump Iris with changes in `auth`2019-05-24T11:44:21ZHai DangBump Iris with changes in `auth`Title says it all.Title says it all.https://gitlab.rts.mpi-sws.org/iris/examples/-/merge_requests/16Shorter barrier proof that uses auth instead of sts.2019-05-28T06:34:03ZRobbert KrebbersShorter barrier proof that uses auth instead of sts.The title says it all :)The title says it all :)https://gitlab.rts.mpi-sws.org/iris/examples/-/merge_requests/15Fix atomic snapshot example2019-03-28T11:58:59ZRodolphe LepigreFix atomic snapshot exampleUpdate to the new prophecy variable interface (with lists).Update to the new prophecy variable interface (with lists).https://gitlab.rts.mpi-sws.org/iris/examples/-/merge_requests/14Add a copy of my new (logically atomic) specification of the Treiber stack al...2019-03-06T16:50:20ZRodolphe LepigreAdd a copy of my new (logically atomic) specification of the Treiber stack algorithm.The example was originally developed here: https://gitlab.mpi-sws.org/lepigre/treiber_stack.The example was originally developed here: https://gitlab.mpi-sws.org/lepigre/treiber_stack.https://gitlab.rts.mpi-sws.org/iris/examples/-/merge_requests/13Master2019-03-06T12:41:15ZDaniel GratzerMasterI messed up git and so I had to make a new request... sorry folks.

Some interesting differences compared to the current logrel development:
### Expressions
- By building on top of heap_lang, we get the nice notations and tactics from heap_lang for free. No more De Bruijn for expressions!
- I only defined semantic types, not syntactic types. One could define syntactic types in the future and prove the fundamental theorem, but I was not too interested in doing that.
- Due to the value restriction, we need to thunk `∀` types. I thus model the type-level abstraction `Λ e` as `λ: <>, e` and the type level application `e _` as `e #()`.
- Due to step-indexing, we need to take a step to prove the typing rule for unfolding recursive types. I defined the unfold operator `rec_unfold e` as `(λ: "x", "x") e`.
### Types
- By having only semantic types, I could use Coq's binders in ∀ and ∃ types, and have nice notations. So, no more De Bruijn for types either.
- I defined a type `lty` as a record containing a predicate over values and a prove that the predicate is persistent. Notably, I used this record in the interpretation of ∀ and ∃ types, and thus no longer have to explicitly require the type to be persistent.
### Typing judgment and typing rules
- I defined the semantic typing judgment `Γ ⊨ e : A` as an `iProp` and stated all of the typing rules using `-∗`.
- I used type classes for operator typing (`LTyUnOp`, `LTyBinOp`) and to keep track of unboxed types (`LTyUnboxed`).

Might be interesting for iris-examples, otherwise I can put it in a different repository.
