Another student who's interested in the project also just contacted me and has a partially-finished port that was done independently. So I think a viable GSoC proposal for this is going to need to go well beyond the initial porting work and aim to get riscv support to first-class status. That probably means putting a strong focus on testing, finding performance bottlenecks (which doesn't necessarily mean writing asm to fix them; rather it might be identifying and reporting compiler bugs that are causing the compiler to generate bad code for the C), etc. Now would be a good time for students interested in the project to jump in with ideas.
