This patch has the necessary changes to Polly in order to support the new CFGPrinter with Profiling Heat Colors.
Reference to the Heat Color patch: https://reviews.llvm.org/rL336000
Thanks! However, I am a little confused: when do I merge this, precisely? It breaks on current LLVM HEAD.
It will need to be synchronised with the merge of the other patch.
Otherwise, the other patch would break Polly.
So, how do we coordinate this? :) Or do you push the patches at the same time?
