Well, one idea is you could help us get a compiler up and running for our home-brew CPU project: https://github.com/hsc-latte/hs32core-rtl

We are at the stage of lacking a lot of software help. We have an assembler, but that's it.

We're expecting some initial chips back in a few months from using the Google/Skywater/Efabless shuttle program: https://efabless.com/open_shuttle_program

Currently we are simulating the CPU in verilog simulators, as well as fpga's. There's a lot of fun very low-level work to be done.
