"""
|
||
|
|
A simple bench runner which delegates to the ./dotest.py 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:
|
||
|
|
|
||
|
|
./bench.py -e /Volumes/data/lldb/svn/regression/build/Debug/lldb -x '-F Driver::MainLoop()' 2>&1 | grep -P '^lldb.*benchmark:'
