--- Comment #2 from Drea Pinski <pinskia at gcc dot gnu.org> --- (In reply to Richard Biener from comment #1) > I'll mention tail merging here (which can only merge full equal blocks, not > tails of blocks). I looked into that, there is a bug about changing tail merging over to use ICF hashing and equals (PR 70032). Though there has been no progress on that one for 10 years.
