[LLVMdev] Function code size estimation

I am working on a pass that finds identical basic blocks and abstracts
them into functions, in order to reduce code size.

To decide, whether particular basic block group is worth factoring
out, I want to estimate code size of some function that uses one of
basic blocks in question 'as is', and after factoring the basic block
into a new function.

Can you please suggest a proper way to do this?
