有些编译器支持“生命周期分割”(live - range splitting)，也就是说在程序的不同部分，变量可以被分配到不同的寄存器或者内存中。
Some compilers support live-range splitting, where a variable can be allocated to different registers as well as to memory in different parts of the function.
使用关键字register修饰最经常使用的变量：告诉编译器这个变量将会被经常用到，要求编译器使用非常高的优先级将此变量分配到寄存器中。
Using register for frequently-used variables: this tells the compiler that the register variable is going to be frequently used, so it should be allocated to a register with a very high priority.
当使用“r ”约束时，GCC在这里可以自由分配任何寄存器。
GCC is free here to allocate any register when the "r" constraint is used.
可以看到test1()中每次加法都需要读取和存储全局变量errs，而在test2()中，localerrs分配在寄存器上，只需要一条指令。
Note that test1 must load and store the global errs value each time it is incremented, whereas test2 stores localerrs in a register and needs only a single instruction.

Even better, for small objects, the JVM can optimize away the allocation entirely and simply hoist the object's fields into registers.
全局变量不会被分配在寄存器上，修改全局变量需要通过指针或者调用函数的方式间接进行。
