The Bessel functions of the second type (Yn) are not defined for negative input and should return NAN with the "invalid" exception raised, in these cases. However, current code checks for infinity and return zero, regardless of the sign. This error is exposed for long double when linking with -lieee. Without this flag, the error is not exposed, because the wrappers for these functions, which use __kernel_standard functionality, return the correct value. Tested for powerpc64le. [BZ #21130] * sysdeps/ieee754/ldbl-128/e_j0l.c (__ieee754_y0l): Return NAN with the "invalid" exception raised when x is -Inf. * sysdeps/ieee754/ldbl-128/e_j1l.c (__ieee754_y1l): Likewise. |
