Looks like someone removed a call to cleanup_cfg as we still have werid things in the RTL:
(jump_insn# # # 1 (set (pc)
(label_ref #))# (nil)
(nil))
(barrier 96 # #)
(code_label 39 # # 7 "" [0 uses])
(jump_insn# # # (addr_diff_vec:SI (label_ref:DI #)
[
(label_ref:DI #)
(label_ref:DI #)
(label_ref:DI #)
(label_ref:DI #)
(label_ref:DI #)
(label_ref:DI #)

]
(const_int 0 [0x0])
(const_int 0 [0x0]))# (nil)
(nil))
(barrier 41 # #)
(code_label 94 # # 2 12 "" [1 uses])
(note# # # 2 [bb 2] NOTE_INSN_BASIC_BLOCK)
In fact this is the only different between the what is done now and what was done in 20050127.
