lowrisc-toolchains build

The original version of this readme has been altered for brevity.

Usage

Open a nix shell after cd'ing into the project's root dir. You can also configure it using direnv.

$ nix-shell

In the shell, just run the toolchain build scrip:

$ ./build-all.sh

The toolchain is produced as a compressed file: lowrisc-toolchain-rv32imcb-20220210-1.tar.xz

This file contains both the llvm and gcc toolchains.

Currently only produces toolchains for the Ibex core.
crosstool-ng has a known issue(crosstool-ng/crosstool-ng#1625) with downloading packages.
