Increasing a variable size, causes Code and RO-Data to increase (instead of RW-Data)

Ehsan Arabi

Hi

I have the following code in cryptography. It is a function which accepts a "key" and "state" inputs and then encrypts state using key.

        uint state[4]={0,1,2,3};
        uint key[8]={1,2,3,4,5,6,7,8};
        Encrypt(state,key);

When I increase size of the "state" variable, I expect to see RW-Data to grow. Because variables are located in RAM. But I see that code size and RO-Data increase instead.

Why ?!

I appreciate your help.

Regards

    Thank you Hans-Bernhard. This was helpful. and I did not know that.

    I am preparing a report on memory usage of numerous algorithms.

    So, I will try to find the maximum RAM usage during the execution of the program. This is what I actually have been looking for. And apparently is not obvious in the compiler global memory report.
