We are developing combined profiles that enable the combination of profiling information from various run of a program (with different inputs) and makes several statistical measures available to the compiler developer to make FDO decisions.

We have tested it with the entire suite of SPEC benchmarks, and we have implemented a tool to check if the profiling information obtained with the new path profiling implementation is consistent with the edge profiling implemented independently in LLVM. Adam also implemented combining profiling.
