59# When specifying a source file of some type, a set of guards can be
60# specified for that file. When get() is used to find the files, if
61# get specifies a set of filters, only files that match those filters
62# will be accepted (unspecified filters on files are assumed to be
63# false). Current filters are:
64# main -- specifies the m5 main() function
65# skip_lib -- do not put this file into the m5 library
66# <unittest> -- unit tests use filters based on the unit test name
67#
68# A parent can now be specified for a source file and default filter
69# values will be retrieved recursively from parents (children override
70# parents).
