    /* PC-relative relocation types
       Typically used for calls.
       Note PCREL17C and PCREL17F differ only in overflow handling.
       PCREL17C never reports a relocation error.

       When supporting argument relocations, function calls must be
       accompanied by parameter relocation information.  This information is 
       carried in the ten high-order bits of the addend field.  The remaining
       22 bits of of the addend field are sign-extended to form the Addend.

       Note the code to build argument relocations depends on the 
       addend being zero.  A consequence of this limitation is GAS
       can not perform relocation reductions for function symbols.  */
