If there's a platform on which GNAT supports subprogram-level linking
(I don't know if such a platform does exist), this could indeed
happen. Without it, it's hardly believable, because the non-inlined
copy will be pulled in in almost all cases.
IIRC, C++ code which uses templates heavily benefits from inlining
also in terms of code size, but the GNAT implementation of generics is
so different that this effect cannot show up.
