  27 # Validate these pipelined linking cases:
  28 # - missing pipe
  29 # - bad file passed via pipe
  30 # - eof on pipe
  31 # - success case
  32 # - differing file orders produce same binary
  33 #
  34 # When testing the success case take care to verify that pipelined linking is actually
  35 # enabled (environment variable is set). Because there is no difference in the command
  36 # line the test will still succeed with pipelined linking turned off, without testing
  37 # pipelined linking.
