例如,编译器为了优化一个循环索引变量,可能会选择把它存储到一个寄存器中,或者缓存会延迟到一个更适合的时间,才把一个新的变量值存入主存。
For example, a compiler may choose to optimize a loop index variable by storing it in a register, or the cache may delay flushing a new value of a variable to main memory until a more opportune time.
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。
Loop unrolling is an example of a transformation that might cause the JIT to have problems register-allocating.
然后再将寄存器127用作循环计数器,将寄存器126用作基指针,并在每个值上执行convert _ to_upper,直到到达缓冲区的底部为止。
You then use register 127 as your loop counter and register 126 as your base pointer, and perform convert_to_upper on each value until you get to the end of the buffer.

最后,”一丝不苟”VI使用大量移位寄存器在一个循环内反复传递数据,在多个并行循环间使用队列传递数据。
Finally, Meticulous VI makes extensive use of shift registers for passing data between loop iterations, and queues for passing data between parallel loops.
