    [PATCH] Generic BUG for x86-64 · c31a0bf3
    Jeremy Fitzhardinge authored
    
    
    This makes x86-64 use the generic BUG machinery.
    
    The main advantage in using the generic BUG machinery for x86-64 is that
    the inlined overhead of BUG is just the ud2a instruction; the file+line
    information are no longer inlined into the instruction stream.  This
    reduces cache pollution.
