  Currently, we support multiple backends for compiling WebAssembly to machine code:
  -- [clif-backend](./clif-backend/): Cranelift backend
  -- [llvm-backend](./llvm-backend/): LLVM backend
  +- [dynasm-backend](./dynasm-backend/): Dynasm backend - super fast compilation, slower runtime speed
  +- [clif-backend](./clif-backend/): Cranelift backend - slower compilation, normal runtime speed
  +- [llvm-backend](./llvm-backend/): LLVM backend - slow compilation, native runtime speed
