pa.c (pa_attr_length_indirect_call): Adjust length of portable runtime and PIC indirect calls.
* config/pa/pa.c (pa_attr_length_indirect_call): Adjust length of
portable runtime and PIC indirect calls.
(pa_output_indirect_call): Remove unnecessary nop from portable runtime
and PIC call sequences. Use ldo instead of blr to set return register
in PIC call sequence.
