[LLVMdev] How to add a pass inside LLVM pass list

[Soumya_Prasad_Ukil]

   My PRE pass is invoked using "opt -load -path-to-*.so-file" -my-pre-pass
. In that case, I was not required to change include/llvm/LinkAllPasses.h
and include/llvm/Transforms/Scalar.h --these two files. What needs to be
done to simply run opt "-my-pre-pass"? In the previous, the required pass
file is loaded first and then run.
