[LLVMdev] Documentation on llvm::CodeModel?

[Yuri]

Where is the documentation on what llvm::CodeModel values mean?
I observe that with Small code model, elf relocation entries become 32 
bit, and the corresponding functions are expected to be in the same 
32-bit memory segment.
But is it possible to make specific call instances still treated as far 
calls?
What is the difference between those values in general?

Googling for llvm CodeModel terms only brings this: 
http://llvm.org/docs/doxygen/html/namespacellvm_1_1CodeModel.html Blank 
doxygen "documentation".

Something should be written up on what those values are for, what is the 
difference between them, etc.
