wasmedge-compile - AOT compiler for WasmEdge

       Copyright © 2019-2022 Second State INC. Licensed under the Apache License, Version 2.0.

       The  wasmedgecompile  subcommand compiles WebAssembly into native machine code, i.e. it is an Ahead-of-
       Time (AOT) compiler.

       For pure WebAssembly, the wasmedge(1) program (or the equivalent wasmedgerun  subcommand)  will  execute
       the  WebAssembly  code  in  interpreter  mode.  However, after compiling it with the wasmedgecompile AOT
       compiler, the wasmedge subcommand can  execute  the  WASM  in  AOT  mode,  with  substantial  performance
       improvements.

       wasmedgecompile was previously known as wasmedgec.

       Assuming a WebAssembly program placed under the file fibonacci.wasm, set up so to export a fib() function
       and accepting a single i32 integer as the input parameter, one can execute the following:

       $ wasmedge compile fibonacci.wasm fibonacci_aot.wasm
       $ time wasmedge --reactor fibonacci_aot.wasm fib 30

       The execution should be much faster compared to interpreter mode:

       time wasmedge --reactor fibonacci.wasm fib 30

   Basicoptions
       --dump
          Dump the LLVM IR to wasm.ll and wasm-opt.ll.

       --interruptible
          Generate a binary that supports interruptible execution.

       --generic-binary
          Generate a generic binary of the current host CPU architecture.

       --optimize
