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.
