commit 223d1cacc5dafe8af53e84608c2d130721c4edcd
Author: Joseph Myers <joseph@codesourcery.com>
Date:   Tue Sep 15 20:36:50 2015 +0000

    Mark fegetround pure (bug 16296).
    
    Bug 16296 notes that fegetround is a pure function and should be
    marked as such in fenv.h.  This patch implements that.
    
    Tested for x86_64 and x86 (testsuite, and that installed stripped
    shared libraries are unchanged by this patch).
    
    	[BZ #16296]
    	* math/fenv.h (fegetround): Use __attribute_pure__.
    	* include/fenv.h (__fegetround): Likewise.
