> What's your decision on this? I think that we ought to standardize on a single order for note copying in the RTL middle-end and the best way to enforce it is to have a single primitive in rtlanal.c, with an optional filtering. Bernd's patch is a step in the right direction, but doesn't enforce the single order. Maybe something based on a macro calling duplicate_reg_note, but not clear whether it's really better.
