1·The loop I used here should be a minor defect, because any decent Just-in-time (JIT) compiler will perform loop unrolling, which lessens the impact.
这里使用的循环应该算是一个缺陷，但是影响不大，因为所有即时（JIT）编译器都会执行循环展开，这会降低循环的影响。
2·Loop unrolling is an example of a transformation that might cause the JIT to have problems register-allocating.
循环展开是一个可能导致JIT分配寄存器出现问题的转换的例子。
3·A standard optimization is loop unrolling; the compiler will unroll the loops to reduce the number of branches.
标准的优化是循环展开；编译器将展开循环，以减少分支的数量。
4·Loop unrolling has been an optimization technique since the dawn of computer programming.
循环展开从计算机编程诞生开始就已经成为一种优化技术了。
5·The story of America’s rapid unrolling of the exceptionalist carpet is very well told by Mr Cumings, professor of history at the University of Chicago.
芝加哥大学历史系教授肯明斯非常精彩的讲述了美国快速展开美国例外论之毯的故事。
