However, space must still be reserved for parameters in case the values need to be saved, especially since the parameters are passed using volatile registers.

然而，在需要保存值的情况下，依然需要为参数预留空间；尤其在需要使用易失性寄存器传递参数时更是如此。

浮点数最好用来表示象测量值这类数值，这类值从一开始就不怎么精确。

这之后，进入到 .bss 部分，此部分与 .data 部分基本相同，惟一的不同之处在于可执行程序本身不包含值，它只关注应该为它们保留多少空间。
