I don't think you can share a basic block between functions; you'll need 
to make a copy of the existing block and put it into your new function.

There is a CloneBasicBlock() function in 
llvm32/lib/Transforms/Utils/CloneFunction.cpp.  That (or some other 
function in that file) may do what you want.
