  The fastest RISC-V sandbox

  

  Yes, I used Spike quite a bit in the beginning. Eventually I moved on to comparing my own instruction logging with objdump -drl program | less.

  These days I have a decent test suite. I verify Go and Zig hello worlds (both running through a surprising amount of code): https://github.com/fwsGonzo/libriscv/blob/master/tests/unit/...

  And I generate a mandelbrot that I compare: https://github.com/fwsGonzo/libriscv/blob/master/tests/unit/...

  Might not cover everything, though. I have tried to integrate with the riscv-tests repository, but it uses a lot of privileged instructions. After I have implemented more of the supervisor extension I will be able to run those tests.
