The offending insn is created by emit_move_insn in loop.c, here:
2354 start_sequence ();
2355 emit_move_insn (m->insert_temp ? newreg : m->set_dest,
2356 m->set_src);
2357 seq = get_insns ();
2358 end_sequence ();
(gdb) p debug_rtx_list (seq, 10)
(insn 45 0 46 (set (reg:DI 69)
(mem/u/c:DI (const:DI (unspec:DI [
(symbol_ref:DI ("bar") [flags 0x40] <var_decl
0x2a95a2f000 bar>)
] 2)) [0 S8 A8])) -1 (nil)
(nil))
(insn 46 45 0 (set (reg/f:DI 67)
(plus:DI (reg:DI 69)
(const_int 2147483648 [0x80000000]))) -1 (nil)
(expr_list:REG_EQUAL (const:DI (plus:DI (symbol_ref:DI ("bar") [flags
0x40] <var_decl 0x2a95a2f000 bar>)
(const_int 2147483648 [0x80000000])))
(nil)))
