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).

First step is to build the riscv-llvm and then use it to build
LDC with it.
If you are trying to do low level stuff then the druntime is
probably out.
Search for embedded d (ARM cortex M, 5(?) part series) for how to
get rid of it (can't find it atm), or ask Adam.
Anyway, good luck!
