Worked on the zephyrproject-rtos/poky repository to address a sporadic issue in CMake’s compiler ABI detection when using GCC with the -pipe flag. The solution involved stripping the -pipe option during ABI detection, which prevented interleaved stderr output from parallel builds and enabled more reliable identification of system include directories. This targeted patch improved the determinism and stability of parallel build processes, particularly in cross-compilation workflows. The work drew on expertise in build system configuration and compiler toolchain management, utilizing cmake and patch to deliver a focused bug fix that reduced CI noise and enhanced overall build reliability.
