4 A simple bench runner which delegates to the ./dotest.py test driver to run the
5 benchmarks defined in the list named 'benches'.
7 You need to hand edit 'benches' to modify/change the command lines passed to the
10 Use the following to get only the benchmark results in your terminal output:
12 ./bench.py -e /Volumes/data/lldb/svn/regression/build/Debug/lldb -x '-F Driver::MainLoop()' 2>&1 | grep -P '^lldb.*benchmark:'
