Worked on stabilizing the Windows build workflow for the Xilinx/llvm-project repository by updating the MSVC compatibility flag in the WinMsvc.cmake configuration. Focused on aligning the build system with LLVM’s minimum MSVC version requirements, the work involved setting the -fms-compatibility-version to 19.28 to ensure compatibility with MSVC 16.8 and newer toolchains. This change reduced the risk of build regressions in Windows environments and improved cross-toolchain portability. Leveraged skills in build system configuration and cmake to enhance CI reliability, streamline contributor onboarding, and establish a more robust foundation for future updates to the Windows toolchain integration.
