AMD AOCC 2.3 Squeezing Out Extra Performance For EPYC Over GCC 10, Clang 11

AMD AOCC 2.3 Squeezing Out Extra Performance For EPYC Over GCC 10, Clang 11: At the start of the month AMD released AOCC 2.3 as the newest version of the AMD Optimizing C/C++ Compiler. AOCC is one of several LLVM/Clang downstream versions maintained by the company with this one being about delivering flagship AMD Zen family compiler support. From an AMD EPYC 7002 "Rome" series processor I recently wrapped up fresh benchmarks of AOCC 2.3 against the current GCC 10 and Clang 11 compiler releases.
