Fixed on the mainline.
We now combine the following RTL to fix the problem:
(insn 16 15 17 0 (set (reg:SI 126)
(lt:SI (reg:CC 127)
(const_int 0 [0x0]))) 382 {*rs6000.md:11380}
(insn_list:REG_DEP_TRUE 15 (nil))
(expr_list:REG_DEAD (reg:CC 127)
(nil)))
(insn 17 16 21 0 (set (reg:DI 128)
(sign_extend:DI (reg:SI 126))) 43 {*rs6000.md:446}
(insn_list:REG_DEP_TRUE 16 (nil))
(expr_list:REG_DEAD (reg:SI 126)
(nil)))
(insn 24 21 30 0 (set (reg/i:DI 3 r3 [ <result> ])
(reg:DI 128)) 312 {*movdi_internal64} (insn_list:REG_DEP_TRUE 17 (nil))
(expr_list:REG_DEAD (reg:DI 128)
(nil)))
Into:
(insn 24 21 30 0 (set (reg/i:DI 3 r3 [ <result> ])
(lt:DI (reg:CC 127)
(const_int 0 [0x0]))) 383 {*rs6000.md:11412}
(insn_list:REG_DEP_TRUE 15 (nil))
(expr_list:REG_DEAD (reg:CC 127)
(nil)))
