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

     --enable-exceptions
             Enable Experimental exception handling

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

     --disable-saturating-float-to-int
             Disable Saturating float-to-int operators

     --disable-sign-extension
             Disable Sign-extension operators

     --disable-simd
             Disable SIMD support

     --enable-threads
             Enable Threading support

     --enable-function-references
             Enable Typed function references

     --disable-multi-value
             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
