I forgot about those. Yes, when excluded those and added a 
/DISCARD/ for the exidx and armexidx, I finally got rid of the 
huge overhead.
Thank you so much!

I guess that the CTFE optimizes any function calls if they reside 
in the startup.d file, because if I keep it in the startup.d, 
then the size stays small, but as soon as I move a called 
function out from the startup.d into its own file, then the 
overhead shows up.
