This will save the old stack pointer and allocate stack memory atomically.
这会保存原来的堆栈指针,并自动分配堆栈内存。
Also, the constant reuse of stack regions tends to keep active stack memory in the CPU caches, speeding up access.
另外,栈的反复使用能够使栈驻留在cpu缓存(cpu caches)中,从而加快数据存取。
Therefore, subsequent, uninitialized stack variables that happen to use the same stack area can return values left over from the prior use of this stack memory.
因此,恰好在随后使用相同堆栈区域的未初始化堆栈变量就可能返回上次使用该堆栈内存时留下的值。
