NAME

     wasm-interp — decode and run a WebAssembly binary file

SYNOPSIS

     wasm-interp [options] file

DESCRIPTION

     wasm-interp decodes and runs a WebAssembly binary file using a stack-based interpreter.

     The options are as follows:

     -v, --verbose
             Use multiple times for more info

     --help  Print a help message

     --enable-exceptions
             Experimental exception handling

     --disable-mutable-globals
             Import/export mutable globals

     --enable-saturating-float-to-int
             Saturating float-to-int operators

     --enable-sign-extension
             Sign-extension operators

     --disable-simd
             SIMD support

     --enable-threads
             Threading support

     -V, --value-stack-size=SIZE
             Size in elements of the value stack

     -C, --call-stack-size=SIZE
             Size in elements of the call stack

     -t, --trace
             Trace execution

     --run-all-exports
             Run all the exported functions, in order. Useful for testing

     --host-print
             Include an importable function named "host.print" for printing to stdout

EXAMPLES

     Parse binary file test.wasm, and type-check it

           $ wasm-interp test.wasm

     Parse test.wasm and run all its exported functions

           $ wasm-interp test.wasm --run-all-exports

     Parse test.wasm, run the exported functions and trace the output

           $ wasm-interp test.wasm --run-all-exports --trace

     Parse test.wasm and run all its exported functions, setting the value stack size to 100
     elements

           $ wasm-interp test.wasm -V 100 --run-all-exports
