At a first glance it seems to inject a custom command into bugpoint and checks the output for that "LLVM ERROR:" regex? Or is there something else?


That’s correct. It runs llc to get the error message using a regex and creates a custom command to check that specific error. Then, it runs bugpoint with the custom command.

I’ll update the description.
