这种方式的缺点占用CPU并需要额外指令。
On the downside, this approach USES the CPU and requires additional MIPS.
这增加了编译器的工作，因为它必须生成这些簿记指令，同时增加了运行时环境的开销，因为它必须执行这些额外的指令。
This creates both work for the compiler, which must generate these bookkeeping instructions, and overhead for the runtime environment, which must execute these additional instructions.
同时这也导致了代码庞大，因为将函数参数保存在堆栈中需要额外的指令。
It also results in code bloat due to the extra instructions required to save function parameters to the stack.
