10843 (LEGITIMATE_PIC_OPERAND_P): Don't normally accept anything that
10844 contains a SYMBOL_REF. Relax this constraint during reload, since
10845 we want to use the predicates, not reload's built-in concept of a

10861 pc-relative operands can fit. For example, a pc-relative operand
10862 can be used as a memory source operand for addsi3, but not as a
10863 memory destination.
10864 * hp320.h linux.h m68kv4.h (LEGITIMATE_PIC_OPERAND_P) as in m68k.h.
