The problem is, that we enter alpha_expand_mov_nobwx with operand[1]:

(mem/s:QI (plus:DI (reg/v/f:DI 72 [ p10 ])
        (const_int 18 [0x12])) [0+8 S1 A16])

This fails "aligned_memory_operand (operands[1], mode)" check.

OTOH, for gcc-4_5 branch, alpha_expand_mov_nobwx is called with:

(mem/s:QI (plus:DI (reg/v/f:DI 74 [ p10 ])
        (const_int 18 [0x12])) [0 S1 A64])
