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. */
