GHC 9.6, Wasm, and GHCJS

[dhess]

Hi! We've just about managed to get our haskell.nix project building with GHC 9.6.2, and now we'd like to build a Wasm target, or at least GHCJS.

From what I can tell, there's no support for cross-compiling to the 9.6 wasm32-wasi "triple." Is there a plan for that?

And for GHCJS, does one use the documented p.projectCross.ghcjs.hsPkgs magic and it will do the right thing with GHC 9.6.2, or does the existing projectCross GHCJS support only work with the old standalone GHCJS compilers?

Bump. Any imminent plans for this?

This will likely happen once we e fixed all the windows issues and are able to update nixpkgs pins again.

Nixpkgs update to binutils 2.36+ (and now the inability to still use 2.35 trivially) has thrown in a pretty bad wrench 😒

(Same with adding the riscv backend).

We're using https://gitlab.haskell.org/ghc/ghc-wasm-meta/ to build our Wasm targets for now. It's nice that it provides a flake for the compiler and tools, but obviously we'd like to take advantage of the haskell.nix ecosystem, as well.

Any plans to implement this once https://github.com/input-output-hk/haskell.nix/pull/2156 is merged?

Hi. I just stumbled upon this now. It seems that the PR above has been merged. I'm also targeting WASM and would like support for it :)
