+**LLVM_USE_LINKER**:STRING
+  Add ``-fuse-ld={name}`` to the link invocation. The value can be an absolute
+  path to your custom linker, otherwise clang will prefix the name with ``ld.``
+  and apply its usual search. For example to link LLVM with the Gold linker, 
+  cmake can be invoked with ``-DLLVM_USE_LINKER=gold``.
+
+**LLVM_ENABLE_LLD**:BOOL
+  This option is equivalent to `-DLLVM_USE_LINKER=lld`, except during a 2-stage
+  build where a dependency is added from the first stage to the second ensuring
+  that lld is built before stage2 begins.
+
 **LLVM_PARALLEL_COMPILE_JOBS**:STRING
   Define the maximum number of concurrent compilation jobs.
