We then use the def macro to define a constant called big-num-str.
之后,使用def宏来定义一个常量,称为big - num - str。
Otherwise, if the expression is not a constant, another macro function is called to round up the value to a power of two.
如果表达式不是常量,就调用另一个宏函数把值向上取整到2的幂。
If you do not define this macro, the usual case, GCC will output the constant pool before the function.
如果没有定义这个宏,在通常情况下,GCC会在函数之前输出。
