FYI. The toolchain benchmark suite derived from Google already includes the FDO mode, and I would suggest to enable it for comparisons. Android build system has (incomplete) FDO integration since Android 2.2[*]. In my experience, it sometimes helps the performance for special cases slightly. Sincerely, -jserv [*] The build system would perform "build-run-build" scheme with the help of ADB, which deploys the profiler on target.
