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

# invocation with no '-e exe-path' uses lldb as the inferior program,
# unless there is a mentioning of custom executable program.
benches = [
# Measure startup delays creating a target, setting a breakpoint, and run
# to breakpoint stop.
'./ -v +b %E %X -n -p',
# Measure 'frame variable' response after stopping at a breakpoint.
'./ -v +b %E %X -n -p',
# Measure stepping speed after stopping at a breakpoint.
