[PATCH] D76813: Remove overly verbose debug from GenericDomTreeConstruction

[Mehdi AMINI via Phabricator via llvm-commits]

Herald added a project: LLVM.

This particular debug shows all the time when I'm processing any MLIR
module:

discovered a new reachable node ^bb0
	discovered a new reachable node ^bb0
	discovered a new reachable node ^bb0
	discovered a new reachable node ^bb0

  ...
  (repeated x1875)

I think that printing all the basic blocks in the function is likely low
value enough that we can get away with removing this.
