## Builds the Renode system simulator
#
# Using sources in sim/renode, this target builds Renode from source and stores
# its output in out/host/renode.
#
# To rebuild this target, run `m renode_clean` and re-run.
#
# This is for debug purpose only. You probably want to use `m renode` target.

# the same commit sha as the release build, it will be treated as up-to-date.
