Open source RISC-V implemented from scratch in one night

Developed in a magic night of 19 Aug, 2018 between 2am and 8am, the darkriscv is a very experimental implementation of the opensource RISC-V instruction set. Nowadays, after one week of exciting sleepless nights of work (which explains the lots of typos you will found ahead), the darkriscv reached a very good quality result, in a way that the "hello world" compiled by the standard riscv-elf-gcc is working fine!

I feel incompetent.
