commit c23805a95d9bc095118299b5965f7f8388e57fc4
Author: Joseph Myers <joseph@codesourcery.com>
Date:   Tue Jun 7 22:54:58 2016 +0000

    Fix i386 asinhl (sNaN) (bug 20218).
    
    The i386 version of asinhl returns sNaN (without raising any
    exceptions) for sNaN input.  This patch fixes it to add non-finite
    arguments to themselves, so that "invalid" is raised and qNaN
    returned.
    
    Tested for x86_64 and x86.
    
    	[BZ #20218]
    	* sysdeps/i386/fpu/s_asinhl.S (__asinhl): Add non-finite argument
    	to itself.
    	* math/libm-test.inc (asinh_test_data): Add sNaN tests.
