title: Step-by-step execution for Intel AT&T assembler?
body: <p>I'm writing a compiler that converts source code (written in a small imperative programming language) to Intel AT&amp;T 32-bit assembler.</p>
  
  <p>I tend to spend a lot of time debugging, because of nasty offset-mistakes etc. in the generated code, and I would like to know if anyone knows of a tool to "walk through" the generated assembler code step-by-step, visualizing what's on the stack etc.</p>
  
  <p>I use Ubuntu Linux as my development platform, and I'm comfortable with the terminal -- a GUI-program would be nice though. Does it exist? Or is there a good reason it doesn't (maybe the problem isn't so straightforward..?)</p>
  
  <p>If you have good ideas for approaching debugging tasks in assembly code, I'll be glad to hear from you!</p>
