如果汇编器不能对程序进行向量化，它会自动试着调用等价MASS标量函数。
If the program is such that the compiler cannot vectorize, it automatically tries to call the equivalent MASS scalar functions.
除了一系列的选项之外，当 -qipa 选项处于可用状态时，如果汇编器不能进行向量化，那么它会试着在决定调用它们之前去内联 MASS 标量函数。
In addition to any of the preceding sets of options, when the -qipa option is in effect, if the compiler cannot vectorize, it tries to inline the MASS scalar functions before deciding to call them.
另外也有用于 IBM PowerPC 970 处理器的 VMX 向量扩展，可以提高向量化代码的性能。
There are also VMX vector extensions for the IBM PowerPC 970 processor that can increase the performance of vectorized code.
