commit 90b6a1e55fdbb3e6a3132742c26eb19666ad9e33
Author: Joseph Myers <joseph@codesourcery.com>

Fix ldbl-128ibm asinhl inaccuracy (bug 16385).
This patch fixes bug 16385, ldbl-128ibm asinhl inaccuracy, which
showed up while attempting to regenerate ulps for powerpc-nofpu for
2.19. The problem here was use of fabs instead of fabsl meaning large
arguments were reduced to the precision of double. Tested for
powerpc-nofpu.
* sysdeps/ieee754/ldbl-128ibm/s_asinhl.c (__asinhl): Use fabsl not
fabs.
