+Subject: [PATCH 1/2] [test] Fix test dependencies when using installed tools
+
+Use the LLVM_UTILS_PROVIDED variable to determine whether test tool
+dependencies should be exposed for clang-tools-extra tests. If clang is
+being built stand-alone and LLVM test tools (FileCheck, count and not)
+are installed, the top-level CMakeLists.txt of clang sets this variable
+to indicate that they will not be built as a part of this build,
+and therefore no dependencies should be emitted for them. This fixes
+the dependency errors when building clang stand-alone with tests
+enabled.
