;;; RUN: %(wasm-interp)s
;;; ARGS: --help
(;; STDOUT ;;;
usage: wasm-interp [options] filename [arg]...
read a file in the wasm binary format, and run in it a stack-based
interpreter.
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
# parse test.wasm, run specific exported function by name with argument
$ wasm-interp test.wasm -r "func_sum" -a "i32:8" -a "i32:5"

-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
-r, --run-export=FUNCTION Run exported function by name
-a, --argument=ARGUMENT Add argument to an exported function 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.
