The AMD Optimizing C/C++ Compiler (AOCC) is a free, open source, optimizing compiler from AMD targeting 32-bit and 64-bit Linux platforms.[1][2] It is based on LLVM Clang 6.0[3] with various additional patches to improve performance for AMD's Ryzen microprocessors. AOCC also includes a version of DragonEgg gcc plugin for Fortran sources.[1][4]

In a May 2017 benchmark comparing AOCC v1.0 to Clang 4 and 5, and GCC 6 through 8, Phoronix found AOCC provided significant but modest improvement over Clang 4.0 in several benchmarks and no difference in others.[4] Compilation time generally increased relative to Clang 4.0. Some benchmarks found some versions of GCC had better performance than some versions of Clang (AOCC included), and vice versa.
