In November 2024, Ray Li developed a portable memory alignment check for the CTSRD-CHERI/cheribsd repository, replacing the Clang-specific __builtin_is_aligned with a standard C implementation. This work focused on low-level programming and memory management, ensuring that alignment checks function consistently across different compilers. By removing reliance on compiler intrinsics, Ray improved cross-compiler compatibility and reduced toolchain dependency risks, supporting broader platform adoption and smoother future transitions. The solution was implemented with careful attention to maintainability and portability, leveraging C and version control best practices. Although no bugs were fixed, the feature addressed a core need for reliable memory alignment handling.
