Hello

I was wondering if I could get some help with understanding the stdu assembly code.

It is a stdu (Store Double Word with Update) Instruction but what I can't understand is the with Update. Based on info I have here it says it updates the base address but what I am is confused is how does it update it.

For example if the code is loaded at 0x0 before the instruction would that then mean that after the instruction is executed would the base address be located at a different address?

That doesn't seem right to me but I figured I would ask since people here have reversed PPC code.

Thank you in advance for all your help.
