commit 06d97e5e6100641df2c379459e41b26bb4d7648b
Author: Joseph Myers <joseph@codesourcery.com>
Date:   Fri Oct 9 21:02:19 2015 +0000

    Fix lrint, llrint, lround, llround missing exceptions for MIPS (bug 16399).
    
    For 32-bit MIPS and some other systems, various of the lrint, llrint,
    lround, llround functions can be missing exceptions on overflow
    because casts do not (in current GCC) result in the proper
    exceptions.  In the MIPS case there are two problems here: MIPS I code
    generation uses an assembler macro that doesn't raise exceptions,
    while the libgcc conversions of floating-point values to long long
    also do not raise "invalid" on all overflow cases (and can raise
    spurious "inexact").
    
    This patch adds support in the generic code (only the functions for
    which this problem has actually been seen) for forcing the "invalid"
    exception in the problem cases, and enables that support for the
    affected MIPS cases.
    
    Tested for MIPS; also tested for x86_64 and x86 that installed
    stripped shared libraries are unchanged by this patch.
