You didn't get my point. If I just start up gdb to debug cc1, cc1 will return with message that it did't know the parameter I pass to it. The parameter should preprocess by xgcc first. then cc1 continue to go. But I start up with xgcc, I can't debug cc1. The website in my first letter, some steps mentioned about how to debug cc1 and xgcc. I could't follow. So I ask the question here. I am sure there are some guy also seen this problem before.
Thanks.
