Contributed to the espressif/llvm-project repository by developing and refining AArch64 features for Arm architectures, focusing on low-level optimization and compiler infrastructure. Over two months, implemented SVE Bit Permutation with streaming mode support, added SME MOP4 and SME TMOP features per the latest ISA specifications, and updated the svluti4_lane intrinsic for ACLE compliance. Enhanced feature gating for Armv9.6 by clarifying dependencies among FEAT_FAMINMAX, FEAT_LUT, FEAT_FP8, and FEAT_NEON, improving toolchain correctness. Work involved C and C++ for compiler development, with thorough documentation and test updates to ensure maintainability and alignment with evolving architectural standards.

Feb 1, 2025February 2025 highlights for espressif/llvm-project focused on Armv9.6 feature dependencies. Implemented explicit dependency rules so FEAT_FAMINMAX, FEAT_LUT, and FEAT_FP8 depend solely on FEAT_NEON, and updated the FP8 dependency chain to be indirectly dependent on FEAT_NEON through FEAT_FP8. Release notes were aligned to reflect these changes. This work improves correctness of feature gating, helps downstream toolchains avoid misconfigurations, and lays a solid foundation for Armv9.6 adoption.

Jan 1, 2025January 2025 — Implemented three critical AArch64 updates in espressif/llvm-project: (1) SVE Bit Permutation (FEAT_SSVE_BitPerm) with streaming mode enablement and refactored flags/guards; (2) SME MOP4 and SME TMOP features (+sme-mop4, +sme-tmop) enabled beyond Armv9.6/sme2p2 per the December 2024 ISA spec; (3) ACLE-compliant svluti4_lane intrinsic now accepts an optional tuple size to align with ACLE spec; accompanied by test, feature-definition, and instruction-information updates.
