And rightly so, since they *use* the pic register unconditionally.
Indeed, that was the whole point of the patch that changed from
using flag_pic in generic code.

I believe all of the ports have been updated:

        * sh.h (PIC_OFFSET_TABLE_REGNUM): Conditionalize on flag_pic.

2002-03-31  Franz Sirl  <Franz.Sirl-kernel@lauterbach.com>

        * config/rs6000/rs6000.h (RS6000_PIC_OFFSET_TABLE_REGNUM): New.
        (PIC_OFFSET_TABLE_REGNUM): Use it and return INVALID_REGNUM if
        !flag_pic.
