[LLVMdev] Can libc++ build for arm cross compiler?

[gamma_chen]

The following web say the libc++abi is ready on arm.http://libcxxabi.llvm.org/spec.html
I try to build libc++ and libc++abi for host x86_64(linux) and target arm(linux) but fail.I have read the web http://llvm.org/docs/HowToCrossCompileLLVM.html
Does anyone know whether it's available for my need? If you know how to build, what is the build options you use?
Best regards
cschen
