### Testsuite update: finale

I did it.

The wasm backend passes the GHC testsuite.

The MR ([!10224](https://gitlab.haskell.org/ghc/ghc/-/merge_requests/10224)) pipeline is all green, the patches are in the final form, and I’m landing it before end of this week.

### What next?

After I return from a break, the next thing I’ll work on is: adding cross backend support to the nofib benchmark suite ([nofib#29](https://gitlab.haskell.org/ghc/nofib/-/issues/29)). Now I consider it a higher priority than user-facing features like JSFFI and Template Haskell. Future patches to the wasm backend will certainly affect performance characteristics of compiled wasm modules, and instead of guessing, I need exact numbers to know how much things have gotten faster/slower, so to make informed decisions.

Hacking nofib won’t take too long though, compared to the GHC testsuite. No weird test cases, no 10+ years of legacy python codebase to debug, the nofib driver is just a shake-based Haskell program. It’ll be a walk in the park.

This is huge! Looking forward to seeing it merged!
