Basically yes, but we have not implemented the integrated assembler yet, so currently rely on an external ARC gnu toolchain.
Plus, there are a wide variety of subtargets that are basically unsupported until we start adding configuration support.

Supporting ARC in lld is a good question. It has not been on my personal short-list, but if you (or others) are interested in specific features, that helps us.
I personally use the bare-metal simulator you sited, though the link you supplied doesn't seem to point out where to get it?
