llvm dev - Nov 2019 - Register Dataflow Analysis on X86

I came across this thread from a couple years ago:

http://lists.llvm.org/pipermail/llvm-dev/2017-November/119346.html

Has there been any progress on RDF for X86? Or is there some other preferred
alternative for performing reachability analysis after register allocation?

Thanks,

Scott Constable

The one blocking issue that existed in the past has been fixed.  I haven’t had
time to do any work on it lately, but I’m not aware of any fundamental problems
that would make it not work on x86.

Do you know whether it has been fixed on the 8.0.1 release?
