Doj文件是vdsp中的目标文件，它使用elf格式，但是根据需要做了一些扩展，.annotation这个section就是其中之一。这个段用于存放一些提示信息。下面以u-boot-2008r1/cpu/cpu.c编译生成的cpu.doj文件为例进行分析。 这个文件的段头如下：   table 0 属性值 附加说明 sh_name 1578 Section name, index in string tbl sh_type FINI_ARRAY Type of section sh_flags 0x00020000 Miscellaneous section attributes sh_addr 0x00000000 Section virtual addr at execution sh_offset 16399 Section file offset sh_size 3232 Size of section in bytes sh_link 0 Index of another section sh_info 0x00000000 Additional section information sh_addralign 1 Section alignment sh_entsize 1 Entry size if section holds table     用vdsp自带的elfdump显示可得到这个section的内容： ---- Section: .annotations [8] ----    Annotations Section .annotations    0x0 (0x0)       ------ Start compilation unit ------ 0x39 (0x39)    [msgid=0, flags=info]

{MOD}标出的部分。 观察红 {MOD}和黄 {MOD}之间的4个字节，很容易可以猜测到这个整数表示了一个段中的偏移量，看看它指向哪里？观察这个偏移量所指向的位置的数据，可以猜到这又是一个偏移量，跟着这个偏移量走，可以发现一个字符串“../../cpu/blackfin/cpu.c”，而第二个偏移量就紧跟在这个字符串的后面。在上表中用浅橙 {MOD}标出了这个字符串和跟在它后面的偏移量。这个字符串在elfdump显示出来就是： 0xb95 (0xb95)           Position [kind=0] Simple position: line 124, column 5 in file '../../cpu/blackfin/cpu.c' 在这行显示中，同时还显示了line和column的值，这两个值很容易可以在字符串数据之后找到，也就是上表中用淡蓝 {MOD}标出的部分。 至于每个annotation的具体内容，则必须根据msgid进行解释，往往都是一个字符串。
