Cross-compilation for iphone

Hi,

I've successfully compiled and cross-compiled llvm 2.6 libraries for many OS and platforms (x86, cell, ppc and arm), but I still have a problem to cross-compile the llvm libraries from Mac 10.5.6 (X86) to iPhone device 3.1.2. I've tryed many ways (CMake, autoconf, XCode 3.2) but i still have a problem for the LLVMXXXCodeGen.a generation, due to a script problem with intrisics.gen. Does anybody test it sucessfully? If yes, is there a special thing to do or can he directly provide me the compiled binaries of LLVM binaries?

Regards
