[Bug math/16357] New: atanhl spurious underflow on x86


https://sourceware.org/bugzilla/show_bug.cgi?id=16357

            Bug ID: 16357
           Summary: atanhl spurious underflow on x86
           Product: glibc
           Version: 2.19
            Status: NEW
          Severity: normal
          Priority: P2
         Component: math
          Assignee: unassigned at sourceware dot org
          Reporter: jsm28 at gcc dot gnu.org

On x86, atanhl (0x1p-16382L) produces a spurious underflow exception.  atanh
(x) is slightly *above* x for small x, so this should not underflow.
