olynch opened issue #10222:

Feature

Provide a webassembly codegen backend for cranelift, in parallel to the x86_64, aarch64, etc. backends.

Benefit

1. This would enable compilers that target CLIF to also produce WASM; specifically debug builds for rustc could target WASM.
2. Cranelift could be used as a WASM-to-WASM optimizer like binaryen.

Implementation

Unfortunately, I don't have an implementation plan and I probably would not work on this, but I would use this in a compiler if it existed.

Alternatives

Compilers could instead emit WASM directly, and then pass that WASM through cranelift to achieve native compilation and optimize it with binaryen for WASM output.
