It looks like OP forked/imported the rustd code only 3 hours ago[1], and yet in README, writes "ra-jit started as a fork of rustd (DioxusLabs), thanks to its authors. It has moved well past it, so use ra-jit rather than rustd." This seems in pretty poor taste, unless this was written by the rustd author? It's not like rustd is some abandoned project -- it was last updated 17 hours ago.
