elliottt edited PR #6307:

Add the --emit-clif <PATH> option to wasmtime compile, making it easier to inspect the intermediate clif produced when compiling a wasm module. The path argument is a directory that will be created if its missing, and it will be populated with files named wasm_func_<idx>.clif, where <idx> is the function index in the wasm module.

Currently this option is only supported when using cranelift to compile a wasm module, and an error will be raised if winch is used instead.

If the user passes an existing file instead of a directory to emit-clif, this will error with Error: File exists (os error 17). It might be worth checking for that case and passing a slightly more helpful error message.

The wording here doesn't quite seem right.

    /// Emit one clif file into this directory for each compiled function

or maybe

    /// The directory path to write clif files into

That's a great point, I'll add a better message for that case!
