2024 05 26 pointers gen

[thedavidmeister]

Motivation

We are getting to the point that manually managing pointers is unscaleable.

For example rainlanguage/rain.uniswap#21 if we want this to have per-network words there are going to be a lot of pointers to maintain.

Solution

Write a script that generates all the pointers needed for the whole repo. It can include related constants such as bytecode hashes etc.

Scope

This only covers the core contracts, followups

• interfaces for pointers #241
• pointer generation for externs #242

Test

https://github.com/rainlanguage/rain.interpreter/actions/runs/9250431782/job/25443936638 should fail due to the codegen building something different to what is currently committed to the repo.

The pointers and hashes themselves are already covered by existing tests.
