10397 contains a SYMBOL_REF. Relax this constraint during reload, since
10398 we want to use the predicates, not reload's built-in concept of a

10414 pc-relative operands can fit. For example, a pc-relative operand
10415 can be used as a memory source operand for addsi3, but not as a
10416 memory destination.
10417 * hp320.h linux.h m68kv4.h (LEGITIMATE_PIC_OPERAND_P) as in m68k.h.
