[LLVMdev] llc and debug information

Figured out my problem, mailing the list in case anyone else runs into the
same issue. I had updated the LLVM tools to the svn version, but not the
front end. It seems that debugging information is handled differently with
the latest version of the tools (perhaps as a result of this
I ended up grabbing a prerelease of llvm2.6 found
and building both the front end and the LLVM tools from source. Using tools
from a consistent period in time solved my problem--oops!
Thanks to everyone who tried to help out :).
