+Subject: [PATCH] Support setting default value for -rtlib at build time
+
+This patch introduces a new cmake variable: CLANG_DEFAULT_RTLIB, thru
+which we can specify a default value for -rtlib (libgcc or
+compiler-rt) at build time, just like how we set the default C++
+stdlib thru CLANG_DEFAULT_CXX_STDLIB.
+
+With these two options, we can configure clang to build binaries on
+Linux that have no runtime dependence on any gcc libs (libstdc++ or
+libgcc_s).
+
+Patch by Lei Zhang!
