ELF 32-bit MSB executable SPARC32PLUS - elf

Question

I have the below code which is extracted by using stings command.
I need to edit the code and compile. But I do not have any idea how to proceed.

Also I do not have any idea what the above code is trying to do.
It would be really helpful if anyone can:
Explain the code.
How to decompile
how to compile after the changes.
Thanks,
Anish

Answer 1

I have the below code which is extracted by using stings command.
I need to edit the code and compile.
Your first step should be: find someone who has a clue. It is unlikely that you'll achieve whatever you are trying to do on your own.
That said, strings does not extract code, it only extracts printable strings from the code. Therefore there is no code to explain. (You should also read man strings if you are to understand anything.)
Assuming you still have the original binary, and not just the strings output, you can disassemble that binary using objdump -d (do read man objdump as well). That output, if it is small enough, you can hope someone would be able to understand and explain to you (you could also try to understand it yourself, armed with SPARC assembly manual, such as this one).
Once you understand what the program does, you could write an equivalent program in C, and finally modify it to do whatever you want. But it may be simpler to write such a program from scratch, rather than going through decompile / modify route.
