这断代码的作用是什么啊

vivi中2410的head.s文件中的

@
@ VIVI magics
@

@ 0x20: magic number so we can verify that we only put
        .long   0
@ 0x24:
        .long   0
@ 0x28: where this vivi was linked, so we can put it in memory in the right place
        .long   _start
@ 0x2C: this contains the platform, cpu and machine id
        .long   ARCHITECTURE_MAGIC
@ 0x30: vivi capabilities
        .long   0
#ifdef CONFIG_PM
@ 0x34:
        b        SleepRamProc
#endif
#ifdef CONFIG_TEST
@ 0x38:
        b        hmi
#endif

请问这断代吗起到什么作用啊？

.long  应该是汇编中的伪操作符，表示存储long型数据，4个字节。关于伪操作符的dd，LZ自己查查资料吧
