Phoronix: AMD Releases Optimizing C/C++ Compiler For Ryzen

Longtime Phoronix readers and AMD Linux enthusiasts probably remember the AMD Open64 compiler for past CPU launches with various compiler optimizations for AMD processors. With Open64 being dead and all the compiler rage these days about LLVM/Clang, AMD has announced the "AMD Optimizing C/C++ Compiler" (AOCC) that's based upon Clang and optimized for Ryzen/Zen processors...

To clarify, does this optimize the compilation process or the compiled application? Or both?

I would imagine the latter. Ryzen is pretty wide and could probably get more IPC with more ILP optimized applications. Hopefully, this could make a difference with single threaded applications.

it improves the compiled application performance

[Kemosabe]

it improves the compiled application performance

But the application has to be compiled with a specialized architecture flag? Thus, no one will benefit from it?

Michael , are you planning on some Ryzen benchmarks with llvm vs aooc? Would be particularly interested in applications that use AMD's AVX implementation

Do benches on Clear Linux

Any AMD developer could comment about it here? Wiil this changes been upstreamed to clang?

I tried to download this, but it has 'AOCC Compiler EULA' and i don't have a time to read this now so no downlad
