# Make the boards under testsuite/boards automatically available to
|
|
# DejaGnu. This is sourced by the `site.exp' file generated in the

# Append GDB's boards dir to DejaGnu's board dir list, making sure
|
|
# that that is the last boards dir in the list, so that boards found
|
|
# in directories appended to the list by either the global config
|
|
# site.exp, or in `$(dirname $DEJAGNU)/boards' override GDB's boards.
|
|
# Unfortunately, there's no standard way to get that behavior. To
|
|
# make it happen, we trace all writes to the $boards_dirs global, and
|
|
# make sure our dir is always the last in the list. This relies on
|
|
# the fact that DejaGnu always writes to this variable, even if just
|
|
# to set it to the empty list, which it does.
