* GH-100987: Allow objects other than code objects as the "executable" of an ↵Mark Shannon2023-06-141-19/+20
| | | | | | | | | | internal frame. (GH-105727) * Add table describing possible executable classes for out-of-process debuggers. * Remove shim code object creation code as it is no longer needed. * Make lltrace a bit more robust w.r.t. non-standard frames.

* GH-103082: Filter LINE events in VM, to simplify tool implementation. ↵Mark Shannon2023-05-121-3/+0
| | | | | | | | (GH-104387) When monitoring LINE events, instrument all instructions that can have a predecessor on a different line. Then check that the a new line has been hit in the instrumentation code. This brings the behavior closer to that of 3.11, simplifying implementation and porting of tools.
