备注Remarks

此内部版本的 sin 函数具有编译器理解的专用化调用约定。This intrinsic version of the sin function has a specialized calling convention that the compiler understands. 它将加快执行的速度,因为它可防止生成副本和帮助注册表分配。It speeds up the execution because it prevents copies from being generated and helps with register allocation.

生成的值被将被推送到浮点堆栈顶部。The resulting value is pushed onto the top of the floating-point stack.
