接下来的部分是一个实际程序的范例—一个离散的Fourier转变(DFT)—显示了在汇编不同汇编器选项时的改善结果。
What follows is a case study of an actual application - a discrete Fourier transform (DFT) - showing the performance improvements that result when compiling with various compiler options.
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.
