[LLVMdev] How to configure the optimization parts in codegen

I would like to know if it's possible to tell LLVM which optimizations
to apply during "Scheduling Formation" (SF) and "Late Machine Code
Right now, I add 1 pass to LMCO via addPassesToEmitFile, the one that
emits the file, that's it. I was wondering if there is a similar list of
available passes for SF and LMCO like there is for IR passes that one
can choose to apply; or is this totally the responsibility of the
backend writer and I can only influence this by an optimization level or
options passed to 'createTargetMachine'?
If anyone could shed some light on this it'd be much appreciated.
