LGTM as a patch provided the -dev thread concludes on removing it (but hold off on submitting until that's clear obviously).

Looks like the backend is incomplete, and nobody has made any substantial changes in a year; clearly a candidate to be removed. LGTM (but give it a few days in case someone objects)

For reference, there are currently four experimental targets in trunk: ARC, AVR, Nios2, and RISCV.

This revision was automatically updated to reflect the committed changes.
