--- Comment #2 from Segher Boessenkool <segher at gcc dot gnu.org> --- rs6000.c print_operand_address does not like (const_int 0) or any other const_int. Power *can* actually have constant numbers as data addresses, but only for instructions that have some D form; and GCC does not support such constant addresses currently. We could do output_operand_lossage, or we could do as most targets do here: call output_addr_const and hope for the best (it will output just "0" with this testcase). Is that preferred?
