Hello llvm-dev,
GVNHoist has been disabled for a while due to test breakages.
I have created a revision where I list the fixed bugs.
I am not sure if I am missing something fundamental that still needs addressing before we flip the switch.
I couldn’t dig out the discussion about exactly what we should do prior to re-enabling it by default.
