关于函数调用的问题！

52rdhzy

请问各位大侠，在一个没有参数传递的函数调用中，在进入函数入口点之前，堆栈里应该只有返回地址吧？
另外，在参数传递过程中，编译器如何知道有几个参数呢？不定参数的函数调用又是怎么编译呢？
多谢！

不清楚,关注中.

1. In fact, armcc and tcc don't store return address in stack. Usually the return address is stored in LR. Of course you can store it in anywhere you like when you write assemble language.
2. You can refer to ARM-THUMB Procedure Call Standard. This book is in your ADS1.2/PDF/specs folder, with name ATPCS.pdf.
