David Brown <david.brown@hesbynett.no> gabbled:

double average(double values[static 4]) {
double total = 0.0;
for (int i = 0; i < 3; i++) {
total += values[i];
}
return  total / 3;
}

Without the "static 4", the compiler can only assume that it can access up to 3 doubles from the "value" array.  But with "static 4", it knows it is safe to read "values[3]" even though the code never needs to do

Not sure I follow. C doesn't care if its safe or not, it'll just try and
read them anyway and if it can't and there's a memory leak or crash, well, tough luck mate. So I don't see why it would make a difference to the resulting
assembler.
