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.
