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.

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).
