             Bug #: 15496
           Summary: ldbl-128ibm nexttowar[d/f/l] generates spurious
                    inexact exception
           Product: glibc
           Version: 2.18
            Status: NEW
          Severity: minor
          Priority: P2
         Component: math
        AssignedTo: unassigned@sourceware.org
        ReportedBy: azanella@linux.vnet.ibm.com
    Classification: Unclassified


This is triggered by glibc testcase "nexttowar[d/f/l] (qNaN, 1.1)". The source
of the issue is sysdeps/ieee754/ldbl-128ibm/s_nexttoward.c,
sysdeps/ieee754/ldbl-128ibm/s_nextafterl.c, and
sysdeps/ieee754/ldbl-128ibm/s_nexttowardf.c all return 'x+y' as return if x or
y is a NaN. A possible fix would just return __builtin_nan[f|l]  instead.

--- Comment #1 from Joseph Myers <jsm28 at gcc dot gnu.org> ---
If this was fixed by the GCC fix for
<http://gcc.gnu.org/bugzilla/show_bug.cgi?id=57363>, please close it as such
(without adding to the list of fixed bugs in NEWS, of course, when it's a GCC
patch rather than a glibc one that fixes it).
