I lifted it straight out of GCC's implementation. Dehao is a good
source of information for it. I did not want to tweak the algorithm at
first so I can compare apples to apples.

The documentation I added in the comments is my own interpretation.
Perhaps we should sit down with Dehao and make sure I was following
his train of thought properly.
