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
