Subject: [bug#63071] [PATCH] gnu: Add emacs-riscv-mode.
Date: Tue, 25 Apr 2023 17:48:41 +0200

* gnu/packages/emacs-xyz.scm (emacs-riscv-mode): New variable.

Hi Gabriel,

your patch didn't apply cleanly thanks to some coding issues, but I got
them to work with a little bit of work.  Below is an expanded patch that
also makes sure that spike actually exists.  It also uses 0.1 as base
version, taken from riscv-mode.el.

Cheers,
Liliana
