Didn't cause a problem.  The constant was pushed to memory:

(insn 10 9 11 (set (reg:DI 70)
        (plus:DI (reg:DI 27 %r27)
            (high:DI (symbol_ref/u:DI ("*L$C0000") [flags 0x2])))) -1 (nil)
    (nil))

(insn 11 10 12 (set (reg/f:DI 69)
        (mem/u/c:DI (lo_sum:DI (reg:DI 70)
                (unspec:DI [
                        (symbol_ref/u:DI ("*L$C0000") [flags 0x2])
                    ] 2)) [0 S8 A64])) -1 (nil)
    (expr_list:REG_EQUAL (symbol_ref/u:DI ("*L$C0000") [flags 0x2])
        (nil)))

(insn 12 11 13 (set (reg:DF 66 [ <result> ])
        (mem/u/c/i:DF (reg/f:DI 69) [3 S8 A64])) -1 (nil)
    (expr_list:REG_EQUAL (const_double:DF -1.0e+0 [-0x0.8p+1])
        (nil)))
