Description

I want to run a simple AOT style cwasm module which is compiled by the wasmtime compile command. So I use the examples in the documentation: Creating hello-world.wasm

I compile the hello-world rust project to wasm32-wasi target and run it with wasmtime successfully:

root@node1: /home/xxx/wasm-by-example/hello-world# cargo build --target wasm32-wasi
   Compiling hello-world v0.1.0 (/home/xxx/wasm-by-example/hello-world)
    Finished dev [unoptimized + debuginfo] target(s) in 0.56s

root@node1:/home/xxx/wasm-by-example/hello-world# wasmtime run target/wasm32-wasi/debug/hello-world.wasm
Hello, world!

However, I failed to run the hello-world AOT format wasm module compiled by wasmtime compile command, the output is:

root@node1:/home/xxx/wasm-by-example/hello-world# wasmtime compile target/wasm32-wasi/debug/hello-world.wasm

root@node1:/home/xxx/wasm-by-example/hello-world# ls
Cargo.lock  Cargo.toml  hello-world.cwasm  src  target

root@node1:/home/xxx/wasm-by-example/hello-world# wasmtime run hello-world.cwasm
Error: failed to run main module `hello-world.cwasm`

Caused by:
    failed to parse `hello-world.cwasm`: input bytes aren't valid utf-8
