[PATCH] D11958: Add a -gmodules option to the clang driver.

[Adrian Prantl via cfe-commits]

aprantl added a comment.

Maybe this is missing the point, but a hash collision between module files with different formats should be highly unlikely because we add the module format into the hash.

  llvm::hash_code Hash =
    llvm::hash_combine(DirName.lower(), FileName.lower(),
                       HSOpts->ModuleFormat);

Or do you mean a collision in spite of this?
