120
       When supporting argument relocations, function calls must be
121
       accompanied by parameter relocation information.  This information is
122
       carried in the ten high-order bits of the addend field.  The remaining
123
       22 bits of of the addend field are sign-extended to form the Addend.
124
 
125
       Note the code to build argument relocations depends on the
126
       addend being zero.  A consequence of this limitation is GAS
127
       can not perform relocation reductions for function symbols.  */
