To write a functional language compiler using this IR, tail call eliminations would be desirable. Are there any plans to support this? I couldn't find any details in the docs.

FYI, Wasmtime is gaining a Config::wasm_tail_call method and --features tail-call CLI flag in https://github.com/bytecodealliance/wasmtime/pull/6774 and (unless you're on s390x) once that lands you can start running .wasms with tail calls on Wasmtime!

As a reminder, tail calls won't be enabled by default until we

[ ] resolve the tail calling convention performance regression (https://github.com/bytecodealliance/wasmtime/issues/6759)

[ ] get s390x support for tail calls (https://github.com/bytecodealliance/wasmtime/issues/6530)

[ ] and meet all the other usual standards for enabling a Wasm feature by default: https://docs.wasmtime.dev/contributing-implementing-wasm-proposals.html#enabling-support-for-a-proposal-by-default

Tail calls are now enabled by default in Wasmtime except for s390x, so I think this is done.
