               Disable Multi-value

       --enable-tail-call
               Enable Tail-call support

       --disable-bulk-memory
               Disable Bulk-memory operations

       --disable-reference-types
               Disable Reference types (externref)

       --enable-annotations
               Enable Custom annotation syntax

       --enable-code-metadata
               Enable Code metadata

       --enable-gc
               Enable Garbage collection

       --enable-memory64
               Enable 64-bit memory

       --enable-multi-memory
               Enable Multi-memory

       --enable-extended-const
               Enable Extended constant expressions

       --enable-all
               Enable all features

       -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

       --wasi  Assume input module is WASI compliant (Export WASI API the the module and invoke _start function)

       -e, --env=ENV
               Pass the given environment string in the WASI runtime

       -d, --dir=DIR
               Pass the given directory the the WASI runtime

       --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

       --dummy-import-func
               Provide  a  dummy  implementation  of  all imported functions. The function will log the call and
               return an appropriate zero value.

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
