Comment (by bgamari):

 I hacked together WorkingConventions/Bisection many months ago while
 trying to track down #11528 (IIRC). It worked reasonably well, although
 these things are always bit fiddly. In your case things are a bit trickier
 still as you don't quite have a nice thumbs-up or thumbs-down result;
 really you want to be able to look at testsuite allocations and plot them
 over time. I recently been working on tools for this, although it requires
 input in the form produced by nomeata's [[https://github.com/nomeata/ghc-
 speed-logs|ghc-speed builder]]
