Is the typo that I used ptr_mode instead of Pmode? Or something else?
I was looking at movdi_symbolic in ia64.md and I don't understand what
it currently has in it, the gen_reg_rtx() call isn't putting the
register it just generated anywhere. Should it be "scratch =
gen_reg_rtx (Pmode);" instead of just "gen_reg_rtx (Pmode);" ?

rtx scratch = operands[2];
if (!reload_completed)
gen_reg_rtx (Pmode);
ia64_expand_load_address (operands[0], operands[1], scratch);
DONE;
