[PATCH] D52927: [CodeGen] Fix for PR39094.

[Adrian Prantl via Phabricator via llvm-commits]

The tools we have available for reducing large inputs are (multi-)delta (http://delta.tigris.org) and creduce (https://embed.cs.utah.edu/creduce/). Delta is a "dumb" implementation of the delta debugging algorithm (same one that is implemented in llvm-bugpoint) that is in my personal experience faster than creduce. I highly recommend spending a day to learn how to use delta; you will find yourself using it a lot :-)
