Avoid instrumentation for direct jump #43

Closed cube0x8 closed 8 months ago

cube0x8 commented 8 months ago

One of my target hangs when executed using QemuEdgeCoverageHelper. I'm not sure about what might cause the target to hang, but removing instrumentation for direct jump fixes the issue.

Since instrumenting direct jump doesn't have any value from a coverage point of view, I think we might avoid it.
