# A test consists of:

# stdout.txt: (optional) the expected stdout from GCC (empty if not present)

# added to GCC's invocation options
# metadata.ini: (optional) if present, can override other properties of the

#
# This runner either invokes all tests, or just a subset, if supplied the
# names of the subdirectories as arguments. All test cases within the given
# directories will be run.
# The optional metadata.ini can contain these sections:
