Updates
- Infrastructure for fusion upstreamed to GCC. Currently supports 10 fusion cases supported by Veyron V1
- Other ports can re-use those cases trivially and the framework is generic enough to add additional cases over time
- Development of store-store fusion support is effectively complete
- Some data on how to evaluate store-pair fusion available, but it's very noisy
- Perhaps just focus on squashing out the obvious cases from the instruction stream data and call it done
- Working through implementation details on store-store case
- Thinking is to start upstreaming once store-store case is handled reasonably well
