The IBM XL C compiler is a very good optimizer, and as a result, the C algorithm delivers superior results to a simple unoptimized assembly language implementation.

IBM XL C 编译器是一个非常好的优化器，结果是 C 算法的性能要比未经优化的汇编语言实现的性能好很多。

Unsurprisingly, neither compiler does nearly as well as the hand-coded assembly language version from the previous article, but for this program XLC outperformed GCC.

毫不奇怪，没有哪种编译器可以接近上一篇文章中手工编写的汇编语言版本，不过对于这个程序来说，XLC的效果比GCC更好。

The compiler supplies the appropriate operand in the assembly language code it generates.

编译器在自己生成的汇编语言中提供了适当的操作数。
