2026-04-17	Tweak trap loop detector heuristic. (#1666)	Prashanth Mundkur	1	-15/+24
	The previous heuristic did not suffice for a few ACT4 tests where the trap count grew slowly but steadily over the xret count. Adjust by introducing an instruction retired callback and resetting the loop detector when a sufficient number of instructions have retired since the last trap. This still catches tight trap loops but allows the above tests to complete successfully. --------- Co-authored-by: Alex Richardson <alexrichardson@google.com>
2026-04-14	Detect potentially infinite trap loops. (#1656)	Prashanth Mundkur	1	-0/+40
	This helps in automated tested environments where an infinite loop caused by a failing test can cause issues. An `xret_callback` is used in combination with the existing `trap_callback` to detect trap loops. The `trap_callback` is now called after the state changes due to the trap are visible.
