[LLVMdev] LLVM for crosscompiling?

Hi, I am trying to use LLVM on x86 with some code intended for another
architecture (IBM Cell). The plan is:
1. foreach $c_files
llvm-gcc -emit-llvm -c -o $bc_file $c_file
2. link $bc_files
3. run my passes with 'opt'
4. llc -march=c
The original code is for the Cell, and uses altivec intrinsics. However,
llvm-gcc complains about not recognizing them. I read that there is
an -maltivec flag for the LLVM PowerPC backend, but my version of llvm-gcc
complains about this "unrecognized command line option." Any hints?
