Thanks, I will give it a try.
In order to tell GCC not to remove the function referenced by
__function_size(<arg>) builtin, I found the FUNCTION_DECL and did
TREE_USED(<arg>) = 1 however this didn't help because the function was
removed nonetheless.
I thought this was the same as using __attribute__((used)) on a function
declaration (which works).
