- 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
