DEBUGGING INSTRUCTION EXECUTION ERRORS IN A SIMULATED COMPUTER SYSTEM
A computing system and associated methods are described for validating behavioral equivalence between different builds of a simulator codebase. Two simulator builds, generated using different build configurations and expected to behave identically for a workload, are selected and used to execute the workload. Trace operations are performed during execution, and checksum values are accumulated and reported at a defined reporting frequency. The checksum values from the executions are compared to detect a mismatch indicative of divergent simulator behavior. When a mismatch is detected, an instruction execution deviation is localized based on an instruction count and the reporting frequency. The techniques support comparison of simulator builds executing on different host operating systems, processor architectures, or translation and code generation configurations, and are applicable to workloads including operating system boot code.
