Things I can do before MMU is turned on

["Rajat Jain" <Rajat.Jain@xxxxxxxxxxxx>]

Hi,

This is a little offtopic but ...

I'm working in an environment where the MMU has yet not been enabled (And hence on PC relative addressing can be used - no absolute addresses). I'm trying to build an exhaustive list (in terms of C language source contructs) of what I am allowed to do and what no. Can you please help me by adding to the list and verifying / disqualifying if anything is wrong:

Allowed
=======
1) Local variables
2) Function calls using function name (right?)
3) if-then-else
4) for / while / do-while


Not Allowed
===========
1) Accessing global variables
2) Function call using function pointers (why?)
3) Switch-case (why?)

Any thing else that can be added to the "Not allowed" list?

Thanks,

Rajat
