[LLVMdev] Why would one use SExt vs CreateIntCast

[Victor Campos]

CreateIntCast is just a helper function that creates the correct
instruction (SExt, ZExt or Trunc) depending on the number of bits you
passed as source and as destination.

So yes, they do the same thing, but the API from IRBuilder just makes
things easier.
