Worked on modernizing memory layout utilities in the google/perfetto repository to ensure compatibility with C++23 and improve long-term maintainability. Focused on removing deprecated APIs, specifically replacing std::aligned_storage with alignas and an inline char array in core components such as SmallVector and MessageArena. This approach preserved alignment and inline storage while aligning the codebase with the C++23 deprecation timeline. The work reduced the risk of compiler warnings and future build failures, simplifying ongoing maintenance. Utilized C++ for implementation, with an emphasis on deprecation handling and memory management, resulting in a more robust and forward-compatible codebase without introducing new features.
