Back-end Developer Contributions:10 commits, 3 comments in 4 months
Contributions summary:Rob primarily focused on improving the Sail RISC-V model, particularly concerning the handling of Load/Store/Atomic (LR/SC/AMO) instructions. They fixed internal errors related to the decoding of invalid LR/SC/AMO widths by preventing their decoding and throwing illegal instruction exceptions. The user extended the execution for the LR/SC/AMO instructions, enabling handling of currently unused, but potentially valid, encodings. They also fixed an issue with LR/SC and atomicity guarantees and added an extension point for physical memory access validation.
