否则，它循环遍历绑定向量数组，寻找非null的绑定句柄指针。

Else, it goes through the binding vector array looking for a non-NULL pointer to binding handle.

在SPE上的标量代码中，将标量值声明为向量和向量指针(即使没有将它们作为向量使用)可以加速代码的执行，因为这样就不会执行非对齐的加载和存储操作。

In scalar code on the spe, declaring scalar values as vectors and vector Pointers (even if you aren't using them as vectors) can speed up code because it doesn't have to do unaligned loads and stores.

如果val2是一个非向量值，就将该值与val1的每个元素相加。

If val2 is a non-vector value, it adds the value to each element of val1.
