autofdo

A tool to convert perf.data profile to AutoFDO profile

This package 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.
