Set GIT_PERF_7821_GREP_OPTS in the environment to pass options to
|
||
|
|
git-grep. Make sure to include a leading space,
|
||
|
|
e.g. GIT_PERF_7821_GREP_OPTS=' -w'. See p7820-grep-engines.sh for more
|
||
|
|
options to try.
|
||
|
|
|
||
|
|
If GIT_PERF_7821_THREADS is set to a list of threads (e.g. '1 4 8'
|
||
|
|
etc.) we will test the patterns under those numbers of threads.
