Usage: $0 [options]
Toolchain:
--cc CC C compiler driver to compiler the benchmark with
Run config:
--cpu-mask MASK MASK is a hex mask of CPU affinity passed to taskset
--linker LINKER Run the benchmark using a specific dynamic linker
--adb Run the test using adb
Timing options:
--multitime N Use multitime to run the benchmark N iterations
--time CMD Use the given time command
Misc:
--keep-tmp-dir Don't delete the temporary directory on exit
Examples:
--cc "\$NDK/toolchains/llvm/prebuilt/linux-x86_64/bin/aarch64-linux-android29-clang
