Updates
- Moved to 2H2024
- No major blockers from initial upstream comments
- EH issue identified. Basically we need to mark the "spills" generate for separate shrink wrapping so that CFI notes get properly generated
- xz performance regression identified and being fixed
- Initial results look promising. We see significant decreases in load/store traffic in multiple parts of spec
- However, interacting poorly with EH, so not quite ready for wider evaluation
- Current thinking is to try separate shrink wrapping, but without changing the placement algorithm with the hope that will get us most of the benefit with minimal cost
