Hi Sandeep,

Clang is a cross-compiler by nature. If you build it without
additional options, you get all back-ends. But a few missing
components need to be supplied to complete the compilation, namely
libraries, special headers and a working linker.

On Linux, that'd be the GNU toolchain (glibc, binutils). On Windows,
you can try MingW. Some other people might help you with which other
ARM toolchains are available.

There are two main documents:

What are the perils and options of cross-compiling with Clang:
http://clang.llvm.org/docs/CrossCompilation.html

A use case: Cross compiling LLVM itself:
http://llvm.org/docs/HowToCrossCompileLLVM.html

These have a tinge of Unix in them, but a lot of it should be relevant
to Windows as well, especially if you use MingW (and Cygwin).

Hope that helps.

cheers,
