See http://sourceware.org/ml/libc-alpha/2012-02/msg00512.html - the correct
result won't underflow in these cases but in whatever cases TLOSS errors are
given I suppose underflow should be raised as well.

--- Comment #6 from Joseph Myers <jsm28 at gcc dot gnu.org> ---
It's now documented that exceptions may not be raised when libm is in the
(deprecated) error-handling modes that use matherr, which are the only cases
where TLOSS errors may occur (since
commit c36e1d2369f149a64c759f3ad6f4cc5a03b03b62).

In passing, it is worth noting that these functions do correctly set errno and
raise the right exception at least one other error (domain error).
