问 Vectors:        LDR     PC,Reset_Addr         
                LDR     PC,Undef_Addr
                LDR     PC,SWI_Addr
                LDR     PC,PAbt_Addr
                LDR     PC,DAbt_Addr
                NOP                            /* Reserved Vector */
                LDR     PC,[PC,#-0xF20]        /* Vector From AIC_IVR */
                LDR     PC,[PC,#-0xF20]        /* Vector From AIC_FVR */我已经把工程中的S3C44B0X.s的IRQ，和FIQ改成LDR PC,[PC,#-0xF20]和LDR PC,[PC,#-0xF20]，编译后怎么还是跟原来的一样                 __startup:
0x00000000  E59FF018  LDR       PC,[PC,#0x0018]
0x00000004  E59FF018  LDR       PC,[PC,#0x0018]
0x00000008  E59FF018  LDR       PC,[PC,#0x0018]
0x0000000C  E59FF018  LDR       PC,[PC,#0x0018]
0x00000010  E59FF018  LDR       PC,[PC,#0x0018]
0x00000014  E1A00000  NOP       
0x00000018  E59FF018  LDR       PC,[PC,#0x0018]
0x0000001C  E59FF018  LDR       PC,[PC,#0x0018]
IRQ中断后跳到IRQ_Addr然后就在0x00000600  EAFFFFFE  B        IRQ_Handler?A(0x00000600)处死循环
