Yes. And manually adding inline is only as good as the knowledge of the user doing so. If somebody implements it right (I did not, I used the easiest approach and used an existing function to estimate the complexity of a subroutine). The compiler can just count the number of the generate instructions or even calculate the length of the procedure and then decide to keep the node tree for inlining.

Well, it depends of course of what happens when. Would you really count final instructions or cycles after all optimization and peephole passes ?

This is not really an issue: actually for inlining mainly instructions/code length matters and e.g. the arm compiler even does this (actually something more complex) as it has to insert the constant tables at the right locations into the code because the relative offsets are limited.
