mdreorg turns

(insn 5 2 18 2 (set (reg:DI 2 r2)
        (const_int -62135769600 [0xfffffff1886b6600])) "t.c":2:5 251
{*arm_movdi}
     (nil))

into

(insn 5 2 18 (set (reg:DI 2 r2)
        (mem:DI (label_ref 29) [0  S8 A64])) "t.c":2:5 251 {*arm_movdi}
     (nil))

but the constant pool entry looks OK to me (just checked on trunk though)=
