# The targets below use GNU parallel to parallelize tests
# 'make all' and 'make parallel' should be equivalent
#
# parallel uses specific logic to make sure the output of the commands
# run in parallel are not mangled. By default, it will reproduce
# the output of each completed command atomically, in order of completion.
#
# With the --keep-order option, we ask it to save the completed output
# and replay them in invocation order instead. In theory this costs
# a tiny bit of performance, but I could not measure any difference.
# In theory again, the reporting logic works fine with test outputs
# coming in in arbitrary order (so we should not need --keep-order),
# but keeping the output deterministic is guaranteed to make
# someone's life easier at least once in the future.
#
# Finally, note that the command we run has a 2>&1 redirection, as
# in the other make targets. If we removed the quoting around
# "$(MAKE) ... 2>&1", the rediction would apply to the complete output
# of parallel, and have a slightly different behavior: by default parallel
# cleanly separates the stdout and stderr output of each completed command,
# printing stderr first then stdout second (for each command).
# I chose to keep the previous behavior exactly unchanged,
# but the demangling separation is arguably nicer behavior that we might
# want to implement at the exec-one level to also have it in the 'all' target.
