[PATCH] D12094: Avoid the propagation of debug locations in SelectionDAG via CSE

[Wolfgang Pieb via llvm-commits]

wolfgangp added a comment.

Adressed review comment on default SDLoc() in getNodeIfExists(). This routine is used in an attempt to take advantage of existing commutative binary nodes by the DAG combiner. No reason to not update the debug location if the node is reused.
