* feat: add small pieces of max theoryRyan Lahfa2024-05-241-0/+39
| | | | | | | | | `0#ty` is neutral for `max` for unsigned integers. Without the `Fact` instances, those theorems are not as automatic as they could be. Signed-off-by: Ryan Lahfa <ryan.lahfa@inria.fr>
* Update scalar_tac to use omega instead of linarithSon Ho2024-05-244-104/+82

* Fix an issue in the progress tacticSon Ho2024-05-211-0/+13

* feat(backends/lean): make `max`-related coercions nicerRyan Lahfa2024-05-211-0/+12
| | | | | | | | | | Situations where you have `coe (max a b) = max (coe a) (coe b)` are often stuck during verification because of the lack of this theorem. With this theorem, `push_cast` works as intended and normalizes even further. Signed-off-by: Ryan Lahfa <ryan.lahfa@inria.fr>
* Merge pull request #164 from RaitoBezarius/ofnat_scalarSon HO2024-05-141-0/+5
|\ | | | | | | feat(backend/lean): Raw Lean literals can be parsed into scalars automatically
| * feat(backend/lean): Raw Lean literals can be parsed into scalars automaticallyRyan Lahfa2024-04-301-0/+5
| | | | | | | | | | | | | | We can use coercion to go to integers, build a scalar out of an int via unification and let the user clear up bounds or let Lean decide them. Signed-off-by: Ryan Lahfa <ryan.lahfa@inria.fr>
* | backends/lean: repair definition of `core.mem.replace`Ryan Lahfa2024-05-131-1/+4
|/ | | | | | Oops, it is supposed to do something with the second argument! Signed-off-by: Ryan Lahfa <ryan.lahfa@inria.fr>

| * | compiler: map `core::mem::swap` to the pure swapRyan Lahfa2024-04-241-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | In the pure functional model, `swap` is mostly about borrow checking and should simplify to the pure swap in our backends. Other backends than Lean are not done in this commit. Signed-off-by: Ryan Lahfa <ryan.lahfa@inria.fr>
| * | compiler: map `core::option::Option::take` to identity functionRyan Lahfa2024-04-171-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | `take` in a pure functional model is the identity function and everything related to borrow checking is handled by the forward/backward mechanism. Signed-off-by: Ryan Lahfa <ryan.lahfa@inria.fr>

* | feat(backends/lean): scalars form a linear orderRyan Lahfa2024-04-231-0/+15
|/ | | | | | | More than c1c33de8, actually, scalars form a linear order with a decidable ≤ operation which is induced by the integer (Z) model. Signed-off-by: Ryan Lahfa <ryan.lahfa@inria.fr>
* lean: scalars form a preorderRyan Lahfa2024-04-121-0/+10
| | | | | | | | | | Via the canonical injection, we can easily define an induced preorder on scalars and inherit all nice properties. It's useful to reason on specific scalar preorders w.r.t. Ordering, see the binary search tree verification example. Signed-off-by: Ryan Lahfa <ryan.lahfa@inria.fr>
