Mining Opportunities for Code Improvement in a Just-In-Time Compilerlly useful for programs whose execution is not dominated by a small set of frequently executed loops. Information about the amount of space and time required to run the mining tool are also provided. In comparison with manual search through the data, the mining tool saved a significant amount of compiler development time and effort.

The Polyhedral Model Is More Widely Applicable Than You Thinkration step and does not compromise the expressiveness of the model. We present experimental evidence that our extension is relevant for program optimization and parallelization, showing performance improvements on benchmarks that were thought to be out of reach of the polyhedral model.

The Hot Path SSA Form: Extending the Static Single Assignment Form for Speculative Optimizationss by designing the analysis phase of a novel optimization — Speculative Sparse Conditional Constant Propagation: an almost obvious extension of Wegman and Zadeck’s Sparse Conditional Constant Propagation algorithm. Our experiments on some SPEC2000 programs proves the potency of such an optimization.

The language and tools community should embrace this new world as fertile source of new challenges and opportunities to advance the state of the art.

We compliment our static type system with a lightweight runtime system to allow for parallelization in the presence of complex data flows. We have a functioning compiler and worked examples to demonstrate the practicality of our solution.

The combination of those three analyses allows our compiler to specialize . variables (the only numerical type in .) to . variables, providing large performance improvements (up to 7.7×) in some of our benchmarks.
