Step-by-step execution for Intel AT&T assembler?

Question

I'm writing a compiler that converts source code (written in a small imperative programming language) to Intel AT&T 32-bit assembler.

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.

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..?)

If you have good ideas for approaching debugging tasks in assembly code, I'll be glad to hear from you!

I like EDB (Evan's Debugger) on Linux. It has a nice, easy-to-use, QT4-based GUI. Its developer's goal is to make it similar to OllyDbg. And it's being actively maintained:

I'm pretty sure it's installable through Synaptic on Ubuntu as well. Enjoy!
