Conclusions

Tree SSA provides a new optimization framework to implement high-level analyses and optimizations in GCC
Goals:
- Provide a basic data and control flow API for optimizers
- Simplify and/or replace RTL optimizations. Improve compile times and code quality
- Implement new optimizations and analyses that are either difficult or impossible to implement in RTL
