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).

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!

Thanks, I'll look around, I have an ARM Cortex M based Arduino 
board so I could test out the process using that.
