Thanks, I will give it a try.
In order to tell GCC not to remove the function referenced by
__function_size() builtin, I found the FUNCTION_DECL and did
TREE_USED() = 1 however this didn't help because the function was
removed nonetheless.

Hello,
I have added a builtin __function_size that is supposed to receive a
pointer to a function and return the size, in words, that the function
takes.
We got it working until GCC4.5. In GCC4.5 became tricky for 2 reasons.
First, GCC 4.5 removes the function if the only reference to the
