+Subject: [PATCH] [compiler-rt cmake] Support overriding llvm-config query
+ results
+
+Support overriding LLVM_* variables obtained from llvm-config when doing
+stand-alone builds. The override of LLVM_MAIN_SRC_DIR is necessary to
+provide LLVM sources when the initial directory used to build LLVM does
+no longer exist when compiler-rt is built stand-alone. This is
+especially the case when building the projects separately in temporary
+directories with unpredictable names.
+
+The code is based on existing CMakeLists.txt from clang. Alike clang, it
+extends the override to all queried variables.
