Hi, I 'm working on Debuggers, basically GDB ... need to change it for a native chipset. I need to know 1. the "chain of functions" GDB goes through when given the command on the Command-Line. 2. Also the "chain of commands" GDB goes through when given commands like break, step etc.

I 'm reading GDB Internals ... but its not helping me much in this regard.

Pleas Help.
