NAME

       wasmedge-compile - AOT compiler for WasmEdge

SYNOPSIS

       wasmedge compile [OPTIONS] [--] WASM_OR_SO [ARG ...]

DESCRIPTION

       The  wasmedge  compile  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 wasmedge run  subcommand)  will  execute
       the  WebAssembly  code  in  interpreter  mode.  However, after compiling it with the wasmedge compile AOT
       compiler, the wasmedge subcommand can  execute  the  WASM  in  AOT  mode,  with  substantial  performance
       improvements.

       wasmedge compile was previously known as wasmedgec.

OPTIONS

   Generic program information
       -h, --help
          Show the help messages. Will ignore other arguments below.

       -v, --version
          Show the version information. Will ignore other arguments below.

   Basic options
       --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
          Use  --optimize  LEVEL  to set the optimization level. The LEVEL should be one of 0, 1, 2, 3, s, or z.
          The default value will be 2, which means O2.

   Statistics information
       --enable-time-measuring
          Enable generating code for counting time during execution.

       --enable-gas-measuring
          Enable generating code for counting gas burned during execution.

       --enable-instruction-count
          Enable generating code for counting WebAssembly instructions executed.

       --enable-all-statistics
          Enable generating code for all statistics options include instruction  counting,  gas  measuring,  and
          execution time.

   WebAssembly proposals
       --disable-import-export-mut-globals
          Disable Import/Export of mutable globals proposal.

       --disable-non-trap-float-to-int
          Disable Non-trapping float-to-int conversions proposal.

       --disable-sign-extension-operators
          Disable Sign-extension operators proposal.

       --disable-multi-value
          Disable Multi-value proposal.

       --disable-bulk-memory
          Disable Bulk memory operations proposal.

       --disable-reference-types
          Disable Reference types proposal.

       --disable-simd
          Disable SIMD proposal.

       --enable-multi-memory
          Enable Multiple memories proposal.

       --enable-tail-call
          Enable Tail-call proposal.

       --enable-extended-const
          Enable Extended-const proposal.

       --enable-threads
          Enable Threads proposal.

       --enable-all
          Enable all features.

EXAMPLE

       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
