BaseBenchmark: Comparing pr with previous commit

How can I run the benchmark between the current julia master and an previous commit, like in this?

Does this describe what you want


That describes how to compare the performance of a PR vs. Julia’s master branch.
So to check if a commit has degraded performance, I’ll have to reset a branch to before the commit and compare it with the current master right?

Yes exactly. Or just compare to the previous commit to the commit that is suspected to have caused the regression.

So, I have to generate a jdl for before #19760. Thanks!
