Worked on stabilizing ARM inline assembly in ASAN-enabled builds for the apache/brpc repository, addressing a persistent assembler error that affected build reliability on ARM targets. Applied expertise in C++ development and assembly language to introduce the .previous directive after the GNU-stack note within ARM inline assembly blocks, ensuring correct section switching and eliminating build failures. This low-level programming fix improved the consistency of sanitizer-enabled CI pipelines, reducing flaky builds and minimizing the need for repeated test runs. The solution aligned with code maintainability standards and enabled smoother pull request integration, ultimately supporting faster delivery cycles and enhanced developer productivity.
