--- Comment #3 from Jay <jay.krell at cornell dot edu> ---
But, the thing is, because optimization can remove the use of such functions,
people are now advocating that we noinline along with the attribute, which
hypothetically is unwarranted damage. Noinline being a partial disabling of
optimization, not complete.
