Known problem. Test needs to be added to the database.  :(

Incomplete feature. The Packed lowering pass hasn't been implemented
yet.

Could you follow those instructions please? For some reason this is a
bug on your platform.

None of those are good. You shouldn't get ICE's from the llvm-gcc
compiler. Not sure what's up with any of that, it doesn't happen on
other platforms. Could you file bugs for these and make sure they are
marked specific to your platform? (FreeBSD?). Thanks. I'm not the person
to diagnose these, Chris will have to do it when he gets back.

Good luck !
