regarding LLVM

Hi All,
I have a question, Today i had read a mail regarding LLVM in gcc
mailing list(http://gcc.gnu.org/ml/gcc/2005-12/msg00045.html) in
which it is wriiten that it is difficult to present souce code
information through LLVM bytecode as it is three-address code style,
Is it really difficult?
Thanks and Regards
Manish
