Bug ID: 19189
Summary: [ldbl-128] log1pl (-qNaN) spurious "invalid" exception
Product: glibc
Version: 2.22
Status: NEW
Severity: normal
Priority: P2
Component: math
Assignee: unassigned at sourceware dot org
Reporter: jsm28 at gcc dot gnu.org
Target Milestone: ---
The ldbl-128 version of log1pl raises a spurious "invalid" exception for a
-qNaN argument. E.g., for mips64:
testing long double (without inline functions)
Failure: log1p (-qNaN): Exception "Invalid operation" set
Failure: log1p_downward (-qNaN): Exception "Invalid operation" set
Failure: log1p_towardzero (-qNaN): Exception "Invalid operation" set
Failure: log1p_upward (-qNaN): Exception "Invalid operation" set

commit af1b2fd08388a3beec3ee7eaa30646d9c002824e

Fix ldbl-128 log1pl (-qNaN) spurious "invalid" exception (bug 19189).
The ldbl-128 version of log1pl raises a spurious "invalid" exception
for a -qNaN argument. This patch fixes this by making the initial
check for infinities and NaNs handle arguments of both signs in such a
way that NaNs result in a NaN being returned (quietly if the input NaN
was quiet) while +Inf results in +Inf being returned and -Inf results
in a qNaN being returned with "invalid" exception raised.
Tested for mips64.
[BZ #19189]
* sysdeps/ieee754/ldbl-128/s_log1pl.c (__log1pl): Make check for
non-finite argument handle arguments with negative sign.
