Hi Kumar, Ginny, Title: Continuing improvement and testing of LLVM's PowerPC backend. Abstract: LLVM, winner of the 2012 ACM Software System Award, has become an integral part of the software-development ecosystem for optimizing compilers, dynamic-language execution engines, source-code analysis and transformation tools, debuggers and linkers, and a whole host of programming-language and toolchain-related components. Now heavily used in both academia and industry, where it allows for rapid development of production-quality tools, LLVM is increasingly used in work targeted at high-performance computing. JLSE's POWER hardware is used for the development of new features for, and ongoing testing of, LLVM's PowerPC backend. This backend allows LLVM to generate highly-optimized code for POWER hardware (including for the A2 cores in IBM's BG/Q supercomputer). The majority of this development work compliments ALCF's bgclang compiler project: https://www.alcf.anl.gov/user-guides/bgclang-compiler Thanks again, Hal ----- Original Message -----

8. LLVM? compiler development on PowerPC - Hal Finkel - 1 IBM Power 740 repurposed from Mira

Hal, could you please provide a description of your project to Ginny Doyle (ccd) for inclusion on our webpage. Please see this page for examples:

http://jlse.anl.gov/projects/

I would appreciate if you can get this info before the end of this week.

Thanks, Kumar
