2024 LLVM Dev Mtg - Towards Useful Fast-Math

2024 LLVM Developers' Meeting https://llvm.org/devmtg/2024-10/ ------ Towards Useful Fast-Math Speaker: Andy Kaylor ------ Slides: https://llvm.org/devmtg/2024-10/slides/techtalk/Kaylor-Towards-Useful-Fast-Math.pdf ----- Fast-math semantic modes provide a way to selectively relax the default rules for numeric consistency used by the compiler. Relaxing these rules can improve performance, but it can also introduce accuracy errors. This talk will describe a technique to track down the cause of such errors and introduce a proposal for new LLVM optimizer infrastructure to make the debugging process easier. ----- Videos Edited by Bash Films: http://www.BashFilms.com
