[LLVMdev] Transparent LTO on Mac OS X

I'm trying to use transparent link-time optimization on Mac OS X.
I've got Xcode 3.2 installed, and I'm trying to compile code with
llvm-gcc -O4. However, I get the following error:
gcc -O4 -o dftables .libs/dftables.o
ld: warning: in .libs/dftables.o, file is not of required architecture
"_main", referenced from:
start in crt1.10.6.o
ld: symbol(s) not found
collect2: ld returned 1 exit status
It seems that the linker doesn't understand the bitcode format. Am I
missing a command line option? Do I need a newer version of XCode?
