Clone ghc repo and check out desired branch or tag.
Edit mk/build.mk to be the following:

Regular Expression Engine Comparison Chart

Many different applications claim to support regular expressions. But what does that even mean?

Well there are lots of different regular expression engines, and they all have different feature sets and different time-space efficiencies.
