If -O3 could inline only static or explicit inline routines, it would
be far less useful than it currently is (for the applications which benefit
from automatic inlining, of course, the majority does not).
Aren't we going to have a list of 10 or how many functions which need to
go through .plt and the rest does not? If yes,
then __attribute__ ((noinline)) for those 10 would suffice.
