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. ----------------------------------------------------------------------- Summary of changes: ChangeLog | 4 ++++ NEWS | 2 +- sysdeps/ieee754/ldbl-128/s_log1pl.c | 4 ++-- 3 files changed, 7 insertions(+), 3 deletions(-) -- You are receiving this mail because: You are on the CC list for the bug.
