I have a simple question, but I am not sure what the answer is. If anyone can possibly help me, it is really appreciated. I compile a test C file. I notice there are a few lines at the beginning of the assembly code. I want to know what it means, but can't figure out one of them. Can anyone tell me what the following line does please? and $0xfffffff0,%esp best regards Chungwei
