# Validate these pipelined linking cases:
# - missing pipe
# - bad file passed via pipe
# - eof on pipe
# - success case
# - differing file orders produce same binary
#
# When testing the success case take care to verify that pipelined linking is actually
# enabled (environment variable is set). Because there is no difference in the command
# line the test will still succeed with pipelined linking turned off, without testing
# pipelined linking.
