Start with this program ...
#include <iostream>
int main()
{
std::cout << "hello, world!" << std::endl;
}
Build it with link-time optimization and the most aggressive setting for smaller code size ...
% tiarmclang -flto -Oz file.cpp -o lto_oz.out -Wl,-c,-m=lto_oz.map
The size numbers are dominated by 1 file from the RTS libraries. These lines are from the MODULE SUMMARY part of the map file ...
