Disable startup variable initialization

[rares.porutiu]

Hello. Can anybody tell me how to disable the memory clear at the begining of program ? I want to retain variable values over a watchdog reset and try a "warm reboot". I cannot seem to find a directive that disables that portion of code.

I looked in the code and it seems no initialization is actualy performed other than some registered pushed on top of the stack.
The memory was cleared by the bootloader I use, I modified that, so disregard the question
