So, either we need to add a new constraint letter for memory that satisfies memory_reg_operand, or find out why predicate hasn't been consulted. -- jakub at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |ebotcazou at gcc dot gnu dot | |org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44484
