    Abstract: The techniques described herein may provide techniques for precise and fully-automatic on-site software failure diagnosis that overcomes issues of existing systems and general challenges of in-production software failure diagnosis. Embodiments of the present systems and methods may provide a tool capable of automatically pinpointing a fault propagation chain of program failures, with explicit symptoms. The combination of binary analysis, in-situ/identical replay, and debugging registers may be used together to simulate the debugging procedures of a programmer automatically. Overhead, privacy, transparency, convenience, and completeness challenges of in-production failure analysis are improved, making it suitable for deployment uses.
