Worked on the GaloisInc/sail-riscv repository to implement per-step pre-step and post-step callbacks in the RISC-V emulator, enabling enhanced logging and tracing around each execution step. This approach introduced callback-based instrumentation, allowing additional processing before and after instruction execution, which improves observability and supports future debugging and metrics collection. The work focused on reliability and maintainability, laying a foundation for more advanced monitoring and performance analysis. Utilized C++ for development within an embedded systems context, applying software architecture principles to integrate the new features without introducing regressions. No major bugs were addressed, as the emphasis was on feature delivery.
