# Constructs lists of source files (full pathnames) to test.  Two
# files are constructed: testsuite_files, which is used to test with
# the default dg-runtest command, and testsuite_files_interactive,
# which is used to test cases that require input to be entered. In
# addition, both lists are pruned of wchar_t tests if the toolchain
# under test does not support wchar_t functionality.
#
# We mimic the mkcheck script in that the first time this is run, all
# existing files are listed in "testsuite_files" in the output
# directory.  Subsequent runs pull the list from that file, allowing
# users to trim the list down to problematic tests, or just run
# paticular directories or sub-directories of tests.
#
# Selecting individual tests can also be done with RUNTESTFLAGS, but
# that doesn't really do all that we are trying to accomplish here.
