Compiler projects using llvm 
# How to generate this file:
# 1. First take a swift file and run xcrun swiftc -g -v file.swift 
# secondfile.swift, make sure the two swift files are in a short path like /tmp/

# 2. Now you can see what the driver does, generate the object files in the 
# tmp directory

# 3. Run obj2yaml on object file to create a yaml file

# 4. I ran delta to reduce this file.
