This adds support for the well-known Boehm GC. It's significantly faster
than our own naive GC and could be used as an alternative on bigger
systems.
In the future, this GC might also be supported on WebAssembly with some
extra work. Right now it's Linux only (though Windows/MacOS shouldn't be
too difficult to add).
This should fix some CI issues we're currently having.
Thanks to @sylv-io for discovering that we need to remove LLVM to avoid
an Xtensa backend linker error.
Node.js 16 is no longer supported, so we can drop support for it as
well.
This also means updating a whole lot of GitHub Actions versions, because
they were updated to work on Node.js 20 instead. For most actions this
should be a relatively small change, but the upload-aftifact action has
had some major changes (which should generally improve things a lot).
This adds a flake.nix file that makes it possible to quickly create a
development environment.
You can download Nix here, for use on your Linux or macOS system:
https://nixos.org/download.html
After you have installed Nix, you can enter the development environment
as follows:
nix develop
This drops you into a bash shell, where you can install TinyGo simply
using the following command:
go install
That's all! Assuming you've set up your $PATH correctly, you can now use
the tinygo command as usual:
tinygo version
You can also do many other things from this environment. Building and
flashing should work as you're used to: it's not a VM or container so
there are no access restrictions.
