13630 contains a SYMBOL_REF. Relax this constraint during reload, since

13647 pc-relative operands can fit. For example, a pc-relative operand
13648 can be used as a memory source operand for addsi3, but not as a
13649 memory destination.
13650 * hp320.h linux.h m68kv4.h (LEGITIMATE_PIC_OPERAND_P) as in m68k.h.
