--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
But then wonder if/how target_reinit works for i?86 32-bit.
Perhaps pic_offset_table_rtx should be cleared in init_emit_regs before
computing it?
  pic_offset_table_rtx = NULL_RTX;
  if ((unsigned) PIC_OFFSET_TABLE_REGNUM != INVALID_REGNUM)
    pic_offset_table_rtx = gen_raw_REG (Pmode, PIC_OFFSET_TABLE_REGNUM);
