title: Does GDB has any keyword for program entry point?
body: <p>I've got a program in c++ with no symbol table and load it in gdb. When I run it, it just exit normally, though I need to trace it. I can't use <code>trace main</code> or <code>trace 0</code>, so either I find out offset of entry point, or find any keyword for it. Of course, you can say, I should just build it with symbol table, but I'm creating a simple IDE with an option of debugging and it should work as well with files with no symbol table.</p>
  
  <p>So, do anyone know either of this? Thanks for any help. Tried googling, but found nothing useful.</p>
