# The following subdirectories with Makefiles are used in several
# of the following tests.  The model is:
#   foo/Makefile - has a "foo" target that waits for the bar target
#   bar/Makefile - has a "bar" target that runs immediately
#                - has a "baz" target that waits for the foo target
#
# So, you start the two sub-makes in parallel and first the "bar" target is
# built, followed by "foo", followed by "baz".  The trick is that first each
# target prints a "start" statement, then waits (if appropriate), then prints
# an end statement.  Thus we can tell if the -O flag is working, since
# otherwise these statements would be mixed together.

# We synchronize the different jobs by having them wait for a sentinel file to
# be created, instead of relying on a certain amount of time passing.
# Unfortunately in this test we have to sleep after we see the sync file,
# since we also want to make the obtaining of the write synchronization lock
# reliable.  If things are too fast, then sometimes a different job will steal
# the output sync lock and the output is mis-ordered from what we expect.
