Re: AVR C++ - how to move vtables into FLASH memory

[Tomasz Francuz]

As I can see in my first post I would like to modify gcc AVR backend to 
support new feature – putting vtables into FLASH not SRAM. That’s why I 
sent my message here.

Ok, I’ve studied a little bit gcc sources, I’ve found sections 
responsible for generating different register loading instructions, and 
indeed there is no information telling to the compiler how to load data 
from FLASH. This is easy to correct, I suppose. But I have no idea how 
compiler generates code responsible for loading pointers from vtable. I 
found code responsible for generating vtable itself. So please, can 
anybody point me to the peace of code responsible for loading pointers 
from vtables?
