Generated from the RISCV Semantics in Haskell using hs-to-coq, with some manually written Coq files too.
You will need Coq 8.9 or master.
riscv-coq depends on the coqutil library. You can get this dependency and build the project using the following commands:
git clone https://github.com/mit-plv/coqutil.git
git clone https://github.com/mit-plv/riscv-coq.git
make -C coqutil
cd riscv-coq/
make
If something doesn't work, you could try to do exactly the same as bedrock2 does, which uses riscv-coq as a dependency and has Travis Continuous Integration, so if you pick a commit with a green tick there, you can be sure to have a working version.
