================ Comment at: clang/unittests/Tooling/ToolingTest.cpp:238-245 Args.push_back("tool-executable"); - Args.push_back("-target"); - // Invalid argument that by default results in an error diagnostic: - Args.push_back("i386-apple-ios14.0-simulator"); - // Argument that downgrades the error into a warning: - Args.push_back("-Wno-error=invalid-ios-deployment-target"); + // Invalid argument (non-existent sysroot path) that will result in a warning. + Args.push_back("-isysroot"); + Args.push_back("/dev/null/sysroot"); + // Argument that will suppress the warning above. + Args.push_back("-Wno-missing-sysroot"); Args.push_back("-fsyntax-only"); ---------------- I'm worried this is going to behave differently when the unit test isn't run on Darwin, since I think `-isysroot` is only valid for Darwin targets and there's no `-arch` or `-target` option. Can you confirm whether this should reproduce properly when run on other hosts as well?
