# Define callbacks and load other libraries. This file is loaded relatively

# "load_gcc_lib" will search the core compiler's .exp collection instead.
#
# The naming rule is that dg.exp looks for "tool-" and runtest.exp looks
# for "tool_" when finding callbacks. Utility routines we define for
# our callbacks begin with "v3-".
#
# libstdc++_* callbacks we don't define, but could:
# ..._option_help prints additional --help output
# ..._option_proc (--foo) process our own options
# ..._init (normal.exp) called once per test file
# ..._finish bracketing function for libstdc++_init
# ...-dg-prune removing output text, see top of system dg.exp
#
# Useful hook: if ${hostname}_init exists, it will be called, almost
# the last thing before testing begins. This can be defined in, e.g.,
# ~/.dejagnurc or $DEJAGNU.
