598233Snate@binkert.org# When specifying a source file of some type, a set of guards can be
608233Snate@binkert.org# specified for that file.  When get() is used to find the files, if
618233Snate@binkert.org# get specifies a set of filters, only files that match those filters
628233Snate@binkert.org# will be accepted (unspecified filters on files are assumed to be
638233Snate@binkert.org# false).  Current filters are:
648334Snate@binkert.org#     main -- specifies the gem5 main() function
658334Snate@binkert.org#     skip_lib -- do not put this file into the gem5 library
668233Snate@binkert.org#     <unittest> -- unit tests use filters based on the unit test name
