Worked on the Xilinx/llvm-project repository to address a critical issue in the AArch64 SME path, focusing on the accuracy of ZA slice calculations for the SMELd1St1 instruction. Using expertise in ARM Assembly and low-level optimization, implemented a targeted bug fix in C and C++ that ensured the 'vnum' argument was correctly incorporated, aligning the logic with ARM documentation. This change improved the reliability and correctness of SME load and store operations, reducing the risk of memory calculation errors. The work demonstrated careful debugging, precise code review, and a commitment to robust, traceable improvements in embedded systems and compiler development.
