Phoronix: ARC Backend Merged In LLVM

LLVM 6.0 SVN/Git now has landed a Synopsys DesignWare ARC processor back-end...

I don't see why anyone would be interested in ARC when there is RISC-V.

There is and there will be much more ARC stuff around than RISC-V for a long while, and many companies will likely have committed to it decades ago for their embedded/microcontroller stuff even if it is not mainstream like ARM or MIPS.

Historically, ARC actually outsells MIPS.

Note, among other things, that ARC is used in the Management Engine for Intel processors (except Atom, which use embedded SPARC cores.)

As for the person saying "why not RISC-V", ecosystem means a lot. RISC-V has a negligible RTOS ecosystem (well, last I looked) and still no mainline Linux port. For those of us that have to design systems for a decade-plus of use, maturity matters.

Cause ARC is configurable and comes with a whole ecosystem of fitting modules (peripherials, busses). Those who need some kind of special-purpose CPU won`t be served with a rather standardized ARM, MIPS or RISC-V.
