  • AMD Optimizing C/C++ Compiler" (AOCC) version 1.1

    In May 2017 there were three nice articles about the "AMD Optimizing C/C++ Compiler" (AOCC) :
    May 16, 2017. AMD Releases Optimizing C/C++ Compiler For Ryzen

    May 19, 2017. Benchmarking AMD's New AOCC Compiler For Ryzen

    May 21, 2017. AMD Ryzen AOCC 1.0 Compiler Tuning Benchmarks

    The verdict by Michael was "so far the benefits of AOCC appear to be very small at least for this Ryzen 7 system".

    Checking it appears that version 1.1 was released in December 15, 2017. The site says:
    Further tuning for AMD Family 17h processors (“Zen” core)
    • Extends LLVM 6.0 trunk (, 30th Nov) with enhancements and optimizations
    • Enhanced loop optimizations, function inlining and other high level optimizations
    • Optimized libraries including AMDLibM (libM math library v3.2.1)
    • Enhanced vectorization, code generation and more
    • LLVM linker (lld) by default (Gold linker no longer required)
    • Continued support for DragonEgg Fortran frontend
    • Tested on RHEL 7.4, SLES 12 SP3, Ubuntu 16.04 LTS

    Michael, it sounds like it is time for a revisit!
