The Transform Dialect's extensibility opens up possibilities for supporting transformations beyond the IR level, such as source-to-source transformations and hardware-specific optimizations. Plans to extend the Transform Dialect may include introducing new operations tailored for source-level transformations, enabling developers to express high-level optimizations directly in the source code. Additionally, enhancements for hardware-specific optimizations could involve integrating domain-specific knowledge into the Transform Dialect to generate optimized code targeting specialized architectures. By expanding the Transform Dialect's capabilities to encompass a broader range of transformations, it can cater to diverse optimization requirements across different stages of the compilation process.
