usage: wast2wasm [options] filename

  read a file in the wasm s-expression format, check it for errors, and
  convert it to the wasm binary format.

examples:
  # parse and typecheck test.wast
  $ wast2wasm test.wast

  # parse test.wast and write to binary file test.wasm
  $ wast2wasm test.wast -o test.wasm

  # parse spec-test.wast, and write verbose output to stdout (including
  # the meaning of every byte)
  $ wast2wasm spec-test.wast -v

  # parse spec-test.wast, and write files to spec-test.json. Modules are
  # written to spec-test.0.wasm, spec-test.1.wasm, etc.
  $ wast2wasm spec-test.wast --spec -o spec-test.json

options:
  -v, --verbose                        use multiple times for more info
  -h, --help                           print this help message
      --debug-parser                   Turn on debugging the parser of wast files
  -d, --dump-module                    print a hexdump of the module to stdout
      --future-exceptions              Test future extension for exception handling
  -o, --output=FILE                    output wasm binary file
  -r,                                  create a relocatable wasm binary (suitable for linking with wasm-link)
      --spec                           parse a file with multiple modules and assertions, like the spec tests
      --no-canonicalize-leb128s        Write all LEB128 sizes as 5-bytes instead of their minimal size
      --debug-names                    Write debug names to the generated binary file
      --no-check                       Don't check for invalid modules
