llvm dev - Sep 2018 - How to cross-compile for ARC in clang?

Hello everyone,

I'm trying to compile my test.cpp for ARC, using this guide
https://clang.llvm.org/docs/CrossCompilation.html.

I've built my LLVM+CLANG with ARC, ARM and X86.

clang -target arc -S test.cpp
Gives me:
error: unknown target triple 'arc', please use -triple or -arch

clang -targer arm works fine

Is there any way to compile for ARC?

Could you run "llc --version"? It should print all targets that were 
built. Arc is an experimental target, did you use 
LLVM_EXPERIMENTAL_TARGETS_TO_BUILD?

I couldn't find any trace of ARC in the Clang source, so I suspect
it's only supported by LLVM at the moment.

Cheers.

Tim,

[haze at haze-pc bin]$ ./llc --version
LLVM (http://llvm.org/):
 LLVM version 6.0.0
 DEBUG build with assertions.
 Default target: x86_64-unknown-linux-gnu
 Host CPU: skylake

 Registered Targets:
   arc    - ARC
   x86    - 32-bit X86: Pentium-Pro and above
   x86-64 - 64-bit X86: EM64T and AMD64

yes, I've set LLVM_EXPERIMENTAL_TARGETS_TO_BUILD=ARC

Oh, that's what I was afraid of.
So there is definetly no way to compile for ARC?
If so, should I write ARC.h(.cpp) in lib/Basic/Targets in order to make it
work?
