我想问一下
2. 32 bit MULtiply bug
While performing multiplication with particular data values, the result is incorrect. The bug is probably indeterministic, but frequent - that means that to detect it one should perform the multiplication several times (64K suggested), and check the result.
这个怎么验证啊,不会每一个数都算一遍吧,有什么好的验证方法吗?
