+Subject: [PATCH] cmake: Allow shared libraries to customize the soname using
+ LLVM_ABI_REVISION
+
+The LLVM_ABI_REVISION variable is intended to be used for release
+candidates which introduce an ABI change to a shared library.  This
+variable can be specified per library, so there is not one global value
+for all of LLVM.
+
+For example, if we LLVM X.0.0-rc2 introduces an ABI change for a library
+compared with LLVM X.0.0-rc1, then the LLVM_ABI_REVISION number for
+library will be incremented by 1.
+
+In the main branch, LLVM_ABI_REVISION should always be 0, it is only
+meant to be used in the release branch.
