Linking tags #215

Closed dhil closed 2 months ago

dhil commented 2 months ago

This patch implements support for importing and exporting tags in the virtual machine. As a consequence tags are now unique to their origin instance, meaning that two different instantiations of the same module yields distinct tags.

The runtime representation of a tag has changed from an u32 to a usize (or native pointer). The identity of a tag is given by its address in the vmcontext.

Resolves https://github.com/wasmfx/wasmfxtime/issues/25.

I haven't implemented the proper runtime representation of tags in the baseline implementation yet. I am planning to defer that to a separate patch.
