Fix ldbl-128ibm log1pl (-1) sign of infinity (bug 19076).
The ldbl-128ibm implementation of log1pl produces an infinity with the wrong sign for log1pl (-1) in FE_DOWNWARD mode. This patch fixes this by changing a division (-1.0L / (x - x)) (incorrect in FE_DOWNWARD mode) to (-1.0L / 0.0L) (correct in all rounding modes). Tested for powerpc. [BZ #19076] * sysdeps/ieee754/ldbl-128ibm/s_log1pl.c (__log1pl): Divide by constant 0.0L when computing infinite result.
