<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">As a general question, do you think you will be able to port these changes to the current, KF5-based master branch? Most of your changes should apply as they are, the major difference at this point is the use of kDebug vs. qCDebug.</p></pre>

<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">This way, the command queue is responsible for this part of maintaining invariants, which makes the code more robust in case somebody decides to call enqueue() elswhere in the future.</p></pre>

However, I have to admit that I don't think this is really the right solution.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">The thing is, commands also have callbacks, and at this point of the code, we simply have no knowledge of whether removing the command messes up assumptions made by the code that issued the command.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">I think we should fix the problem at the source, i.e. going through the various subsystems that issue the duplicate commands and making them smarter about when to update.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Finally, this code leaks memory; the command list stores pointers, which have to be deleted explicitly.</p></pre>

- switch the assembler flavor from AT&T to Intel and back in the dissassembler widget
- remove StackList commands from the queue when a new Exec command arrives. This reduces the wait time when stepping through the code quickly.
- remove duplicated command in the queue. Mostly to eliminate duplicate variable updates.
- show the pending command in the command queue. This is purely for debugging and to check which commands are currently pending.
- slight improvements to memory view to use sizeof() when no size argument is given</p></pre>
