description:
configs: add command-line option to stop debug output
This patch adds a --debug-end flag to main.py so that debug output can
be
stoped at a specified tick, while allowing the simulation to continue.
It is
useful in situations where you would like to produce a trace for a
region of
interest while still collecting stats for the entire run. This is in
contrast
to the currently existing --debug-break flag, which terminates the
simulation
at the tick.
