commit 2286e84a642ddeef1df3c485cd63ce354d266140
Author: Siddhesh Poyarekar <siddhesh@sourceware.org>

    Fix cos computation for multiple precision fallback (bz #20357)
    
    During the sincos consolidation I made two mistakes, one was a logical
    error due to which cos(0x1.8475e5afd4481p+0) returned
    sin(0x1.8475e5afd4481p+0) instead.
    
    The second issue was an error in negating inputs for the correct
    quadrants for sine.  I could not find a suitable test case for this
    despite running a program to search for such an input for a couple of
    hours.
    
    Following patch fixes both issues.  Tested on x86_64.  Thanks to Matt
    Clay for identifying the issue.
    
    	[BZ #20357]
    	* sysdeps/ieee754/dbl-64/s_sin.c (sloww): Fix up condition
    	to call __mpsin/__mpcos and to negate values.
    	* math/auto-libm-test-in: Add test.
    	* math/auto-libm-test-out: Regenerate.
