# 🌲 Arboreta 🌲

A small library for facilitating proofs about rooted labeled trees (or rose trees/generic trees) in Coq, and helping verifying C code that involves the use of array-based trees with VST (still, in Coq). 

## Building Requirements

Coq:

- 8.16.1

Required Coq package(s) for compiling the files inside `utils/` and `clocks/`:

- `stdpp` 1.8.0

Required Coq package(s) for compiling the files inside `vst/`:

- VST 2.11.1

- CompCert 3.11

The requirements above might be satisfied by installing [this version of Coq platform](https://github.com/coq/platform/blob/main/doc/README~8.16~2022.09.md). 

## Directory Organization

- `clocks`: Coq formalization of tree clock and degenerated tree clock (with no attached clock information). 

- `utils`: Coq utility files. 

- `extraction`: Originally for testing the Coq implementation via extraction; now for testing various things. Check [`extraction/README.md`](extraction/README.md) for details. 

- `vst`: VST verification of tree clock (in C). 

- `race-detector`: The data race detectors used in evaluation. 

The pure part of the library (including **Arboreta-P** and the loop invariant template for non-recursive traversals) is in the monolithic file `utils/rosetree.v`. For the separation logic related part, it is in `vst/verif_treeclock.v`. Currently we have only instantiated the separation logic related part for tree clock; we will later decouple it from tree clock and make it reusable for different tree data structures. 

## Building Instructions

```shell

bash clightgen.sh   # only if you are going to compile the files inside `vst/`

make

```
