Step Into/Over does not function as expected when HLT is encountered #145

Closed hasithvm closed 11 years ago

hasithvm commented 11 years ago

When using step into/over to debug , the step into/over buttons do not trigger expected functionality when HLT is executed.

Expected When stepping into/over a HLT instruction, the message box indicating HLT status should trigger if the IF is not set.

Observed No message box indicating HLT has been reached, instruction highlighting disappears.

This issue is indicative of another, which is that stepping currently runs in the GUI thread. This needs to be fixed, because if a step out takes a long time, then the GUI locks up until (hopefully) it finishes.

Is this tied into higher-than-expected CPU usage at idle? top says libra-qt idles at 6-7% CPU usage.

No, it isn't, I've opened issue #146 for that.
