I would like to know where I can get started understanding disassembly in this format. I am familiar with OllyDbg from back in my windows days but this is a bit different, and would like to get the semantics down.
Example of part of what I'm talking about objdump -d loops:
080483b4 <main>:
80483b4: 55 push %ebp
80483b5: 89 e5 mov %esp,%ebp
80483b7: 83 ec 10 sub $0x10,%esp
80483ba: c7 45 f8 00 00 00 00 movl $0x0,-0x8(%ebp)
80483c1: c7 45 fc 00 00 00 00 movl $0x0,-0x4(%ebp)
80483c8: eb 11 jmp 80483db <main+0x27>
80483ca: 83 45 f8 01 addl $0x1,-0x8(%ebp)
80483ce: 81 7d f8 f4 01 00 00 cmpl $0x1f4,-0x8(%ebp)
80483d5: 75 f3 jne 80483ca <main+0x16>
80483d7: 83 45 fc 01 addl $0x1,-0x4(%ebp)
80483db: 81 7d fc f4 01 00 00 cmpl $0x1f4,-0x4(%ebp)
80483e2: 75 ea jne 80483ce <main+0x1a>
80483e4: c9 leave
80483e5: c3 ret
Thank you
