"Didn't work" means... what? Compilation failed? Program doesn't work?
Either way: what mesages do you get?
Are there any differences when compiling with the standard 4.2 gcc?
(Some distributions install gcc 4.0, you have to explicitly install
gcc-4.2 to get the equivalent GNU compiler.)

No problem, just run a few preliminary tests. This will allow people to
determine what component the problem is in: code generator (if gcc works
but gcc-llvm doesn't), language semantics (if neither gcc nor llvm-gcc
work - probably a gcc problem then, playing around with -O2 or -O0 might
make the problem go away; if that still doesn't help, there's a real
possibility that the 3D driver or hardware is broken).
Darkplaces is probably not a good test for the LLVM test suite. Any
failure may be due to problems with the 3D hardware or the drivers,
