2017 LLVM Developers’ Meeting: C. Chandrasekaran & M. Maggioni “Apple LLVM GPU Compiler ...”

http://www.LLVM.org/devmtg/2017-10/ — Apple LLVM GPU Compiler: Embedded Dragons - Marcello Maggioni and Charu Chandrasekaran Slides: http://llvm.org/devmtg/2017-10/slides/Chandrasekaran-Maggioni-Apple%20LLVM%20GPU%20Compiler.pdf — The adoption of LLVM to develop GPU compilers has been increasing substantially over the years, thanks to the flexibility of the LLVM framework. At Apple, we build LLVM-based GPU compilers to serve the embedded GPUs in all our products.The GPU compiler stack is fully LLVM based. In this talk, we will provide an overview of how we leverage LLVM to implement our GPU compiler: in particular we will provide details about the pipeline we use and we will describe some of the custom passes we added to the LLVM framework that we are considering to contribute to the community. Additionally, we will discuss some of the challenges we face in building a fast GPU compiler that generates performant code. — Videos Filmed & Edited by Bash Films: http://www.BashFilms.com
