* flow.c (commit_one_edge_insertion): Be prepared for a return
insn to be inserted on the edge with a normal jump. * jump.c (jump_optimize_1): Don't look to create return isns. * flow.c (flow_delete_insn): Don't adjust reference count of notes. * jump.c (jump_optimize_1): Likewise. (returnjump_p): Verify the argument is a JUMP_INSN. * rtl.def (NOTE): Add 5th element for NOTE_INSN_DELETED_LABEL. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@33950 138bc75d-0d04-0410-961f-82ee72b054a4
