Google has open-sourced their toolchain for providing automatic feedback-directed optimizations from perf data profiles to what can be used by GCC and LLVM.

Going back years Google has been working on AutoFDO optimizations for GCC and then last month they released similar support got LLVM. Google has now open-sourced their complete AutoFDO tool-chain.

From their new AutoFDO GitHub repository, "The repository contains a tool to convert perf.data profile to AutoFDO profile that can be used by GCC and LLVM. Each compiler is supported by a different tool. For GCC, use 'create_gcov'. For LLVM, use 'create_llvm_prof'. The two tools have compatible command line flags. However, the outputs are incompatible. You cannot use the profile generated for GCC in LLVM and vice-versa."

Dehao Chen announced the open-sourcing of all their AutoFDO work to the GCC developers. More details can be found via the Wiki.
