commit f1226a2ae370b1412b5e31a8535ad58a9174dd0a
Author: Joseph Myers <joseph@codesourcery.com>

    Fix llrint, llround missing exceptions for ARM (bug 15470).
    
    Similar to the recent fix for MIPS, ARM is also missing correct
    exceptions on overflow from llrint and llround functions because casts
    from floating-point types to long long do not result in correct
    exceptions on overflow.  This patch enables the fix for this for ARM.
    
    Tested for ARM.
    
    	[BZ #15470]
    	* sysdeps/arm/fix-fp-int-convert-overflow.h: New file.
