But the output of my 'dis mss.o' is like the followings : "38a8: 41 86 00 24 ??? 38ac: 3d 20 00 00 ??? 38b0: 39 69 00 00 ??? 38b4: 80 6b 00 00 ??? 38b8: 48 00 00 01 ??? 38bc: 3d 20 00 00 ??? 38c0: 39 69 00 00 ??? 38c4: 38 00 ff ff ??? 38c8: 90 0b 00 00 ??? 38cc: 3d 20 00 00 ??? 38d0: 39 69 00 00 ??? 38d4: 80 0b 00 00 ??? 38d8: 39 20 ff ff ??? 38dc: 7c 80 48 00 ??? 38e0: 41 86 00 24 ??? 38e4: 3d 20 00 00 ??? 38e8: 39 69 00 00 ??? 38ec: 80 6b 00 00 ??? 38f0: 48 00 00 01 ??? 38f4: 3d 20 00 00 ??? 38f8: 39 69 00 00 ??? 38fc: 38 00 ff ff ???" Can you please let me know why this is not readable in my case ?

This part of the file looks like it is just raw data. Could be constants needed for operation, could be static pointers. Could static ints, could be anything. .o files have both code and data in them. Without reverse engineering the whole code, you'll never know. All the structured information about it is gone by the time its an .o file. By that level, the assembly language earlier on in the listing will be referencing the data by raw data location. It also could be that the .o file you have is for a different architecture than what you are running on now. Ie. i386 code is slightly different than x64, which is alot different than SPARC code, is alot different than PPC code, is alot different than HP/PA code. If you do have a PPC based .o file on an i386 box, there are other tools to disassemble it, it could just be raw data as well that makes no sense in any context.

Again, what are you trying to do? Where did you get this file? People would be able to help you better if they could be sure this wasn't some random file you accidentally downloaded. -- Brandon Hume - hume -> BOFH.Ca, http://WWW.BOFH.Ca/

I have an SPARC Sun Solaris 8 platform that will load the mss.o object file on an VxWork 5.2 target . According to the 'nm mss.o' output , it contains the SS7 function that I want to slightly modify it to accomodate with the new third party network element received . To this end , I tried for 'dis mss.o' but as you see the output is not readable . Can you please correct me ? |
