[LLVMdev] Adding an object to llc (analysis pass)

[Fernando Magno Quintao Pereira]

Hi. I remember I had some similar problems some weeks ago. My problem was
that I was using "makellvm llc" from my working directory, but it caused
the libraries to be "unsynchronized". To solve, just make your application
from the root directory (e.g.: $HOME/llvm> make).
