        <pre>consider

void foo_good();
extern inline void foo()
{
    foo_good();
}
void bar()
{
    foo();
}

using: -fsemantic-interposition -fPIC -O2
expected: no reference to foo, only to foo_good.
got: interposable call to foo.

with -O0 i expect a local call to foo that is not interposable.

(i don't think iso c requires either way, but
gcc implements it the described way on elf
platforms and existing software relies on it.
at least on linux targets clang should follow.)</pre>
