2019 LLVM Developers’ Meeting: D. Ferrer “LLVM-Reduce for testcase reduction”

—
LLVM-Reduce for testcase reduction - Diego Trevino Ferrer

Slides: Coming soon
—
LLVM-Reduce is a new and powerful tool that can reduce IR testcases in new and interesting ways; reducing IR code to almost a fraction of the original size.

In this talk I will demonstrate how to use the tool and how to build a proper interesting-ness test - a key element used by llvm-reduce in order to minimize testcases. The more powerful the test is, the better testcase it will produce.
