I am in a developing process for a new llvm backend (target). Can I create the new target subdirectory out of source. My point is that I want to create a separate svn repo only for my new backend directory and use the llvm project as an external repository. I have to amke some changes to llvm project, to integrate my backend to the llvm, but I won’t commit my changes to the llvm repo. I only want to commit the changes to my separate backend svn repo, but I want to update the llvm external repo. This design should be like a llvm read only (but updatable) repo, and a commitable, separate backend repo.
Is this design feasible ?
