Path of least resistance towards D running on RISC-V

[e-y-e via Digitalmars-d]

The HiFive1 [1] is the first commercially available RISC-V system 
on chip, programmable in C using the Freedom E SDK [2].

I have ordered one to tinker with and to help learn C properly, 
but I think it would be amazing to see D running on systems like 
this. I am a novice in low level stuff really, so I wonder what 
is the best way for this to happen? I assume LDC is the best 
compiler for the job (an LLVM supporting RISC-V exists [3] but 
needs to be upstreamed).

What's your opinion? Personally I think it would be a good 
demonstration of D as a cutting-edge systems language if it could 
be run on resource-constrained RISC-V systems like the HiFive1 
(no FP, low memory & CPU).
