This is a simple example of how to use the rv64emu crate in a no_std environment.
- board: esp32-s3 with 8MB PSRAM, 8MB flash
- environment: esp-rs/esp-hal

crossbeam-utils
error[E0432]: unresolved imports `core::sync::atomic::AtomicI64`, `core::sync::atomic::AtomicU64`
--> /home/leesum/.cargo/registry/src/mirrors.ustc.edu.cn-61ef6e0cd06fb9b8/crossbeam-utils-0.8.16/src/lib.rs:79:49
Because esp32-s3 is a xTensa architecture, and the toolchain is "xtensa-esp32s3-none-elf", which have't support by rust mainline yet. So we need to add "xtensa-esp32s3-none-elf" to crossbeam-utils-0.8.16/no_atomic.rs
#[allow(dead_code)] // Only crossbeam-utils uses this.
