Hello @MaskRay @bazuzi,
Looks like one of the commit ([Driver] Ensure ToolChain::LibraryPaths is not empty for non-Darwin) broke the clang-arm64-windows-msvc-2stage bot here:
https://lab.llvm.org/buildbot/#/builders/120/builds/6489
Old compiler-rt lib seems still used "--dependent-lib=clang_rt.builtins-aarch64.lib"
