Brian and I hammered out a document this week that captures what we think is emerging as our shared understanding of how adapt the JVM to support primitive classes.
It is still white-hot, not even off the press, but I think it is worth looking it even in its unfinished state. https://github.com/openjdk/valhalla-docs/blob/main/site/design-notes/state-of-valhalla/03-vm-model.md That is the JVM side, only. Most of it is already prototyped in HotSpot, some is not. I’ll let Brian speak for the valhalla-doc repository as a whole, but I wanted to get this out there for tomorrow’s meeting. — John
