This commit implements registering unwind information for JIT functions on Windows so that the operating system can both walk and unwind stacks containing JIT frames. Currently this only works with Cranelift as lightbeam does not emit unwind information yet. This commit also resets the stack guard page on Windows for stack overflow exceptions, allowing reliable stack overflow traps. With these changes, all previously disabled test suite tests (not including the multi-value tests) on Windows are now passing. Fixes #291.
Python 3 extension for interface with Wasmtime/Cranelift.
Build
First, you'll need to install some Python dependencies:
$ pip3 install setuptools wheel==0.31.1 setuptools-rust
Next you can build the extension with:
rustup run nightly python3 setup.py build
Note that a nightly version of Rust is required due to our usage of PyO3.
This will create a directory called build/lib which you can add to
PYTHONPATH in order to get import wasmtime working.
