Yes, lib/Basic/Targets looks like the basic entry point. If you don't
care what ABI or CPU you get that might be enough. Otherwise you'll
want to investigate lib/CodeGen/TargetInfo.cpp and
lib/Driver/ToolChains/Arch/ARC.cpp too. There are other
target-specific details scattered around the source, but those are the
main ones to get started.

Cheers.
