Possibly (but likely of similar concern for other small embedded targets)
The problem is that the initialization data which is linked in .data (stored in
readable flash/rom)
is first copied to RAM, prior to then being copied to the data structure which
may require
initialization. (resulting in a needless redundant copy chewing up precious
RAM).
As in for example:
struct s{
long a;
long b;
long c;
long d;
};
void main (void){
volatile struct s x = {0, 1, 2, 3};
volatile struct s y = {0, 1, 2, 3};
/* etc. */
}
