--- Comment #11 from Segher Boessenkool <segher at gcc dot gnu.org> --- (In reply to Jakub Jelinek from comment #7) > Ah, create_log_links wants to work like that. > So, the bug seems to be that insn 108 has REG_DEAD (reg:CC 17 flags) note. > It doesn't initially, but it is added during 106 -> 108 combination But that combination should never have been made: flags is set in insn 107!
