commit 2ca725c594e0c186d928dc0823be7d8b5976112c
Author: Joseph Myers <joseph@codesourcery.com>
Date:   Fri Feb 27 17:48:37 2015 +0000

    Fix ldbl-96, ldbl-128ibm atanhl inaccuracy (bug 18046, bug 18047).
    
    The threshold in ldbl-96 atanhl for when to return the argument,
    0x1p-28, is a bit too big, and that in ldbl-128ibm atanhl is much too
    big (the relevant condition being x^3/3 being < 0.5ulp of x),
    resulting in errors a bit above the limits of those considered
    acceptable in glibc in the ldbl-96 case, and in large errors in the
    ldbl-128ibm case.  This patch changes those implementations to use
    more appropriate thresholds and adds tests around the thresholds for
    various formats.
    
    Tested for x86_64, x86 and powerpc.  x86_64 and x86 ulps updated
    accordingly.

    	* sysdeps/ieee754/ldbl-128ibm/e_atanhl.c (__ieee754_atanhl): Use
    	0x1p-56L as threshold for just returning the argument.
    	* sysdeps/ieee754/ldbl-96/e_atanhl.c (__ieee754_atanhl): Use
    	0x1p-32L as threshold for just returning the argument.
    	* math/auto-libm-test-in: Add more tests of atanh.
    	* math/auto-libm-test-out: Regenerated.
    	* sysdeps/i386/fpu/libm-test-ulps: Update.
    	* sysdeps/x86_64/fpu/libm-test-ulp: Likewise.
