Phoronix: AMD AOCC 3.1 Compiler Performance On EPYC 7003 / Zen 3

Last week AMD released their AOCC 3.1 compiler that is their downstream of LLVM Clang/Flang and carrying various yet-to-be-upstreamed patches for benefiting their latest processors. While just a point release, curiosity got the best of me for firing up benchmarks of this latest AMD Optimizing C/C++ Compiler release.

AOCC 3.1 is worth trying. Quite quick to setup and gives a few more % over vanilla llvm12 on amd zen cpus. But keep in mind it is slightly slower.
Michael great benchmarks!
