Worked on compiler infrastructure and governance across the rust-lang/gcc and zephyrproject-rtos/gcc repositories, focusing on ARM architecture and embedded systems. Addressed AArch64 system register intrinsic gating by removing architecture-based restrictions and adding targeted tests in C to ensure correct, portable behavior. Improved repository processes by updating MAINTAINERS files to clarify reviewer responsibilities and maintain accurate governance data, supporting smoother onboarding and compliance. Emphasized test-driven development and cross-repository consistency, particularly in compiler development and documentation. The work balanced technical bug fixes with process improvements, resulting in more reliable system register handling and streamlined review workflows for the AArch64 port.
