 ``RegisterScheduler::FunctionPassCtor`` is significantly different from
 ``RegisterRegAlloc::FunctionPassCtor``.
 
-To force the load/linking of your register allocator into the
-:program:`llc`/:program:`lli` tools, add your creator function's global
-declaration to ``Passes.h`` and add a "pseudo" call line to
-``llvm/Codegen/LinkAllCodegenComponents.h``.
