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

# early, and before any other file we write ourselves. "load_lib" will

|
# find anything in the DejaGNU installation tree, or in our lib directory.
|
|
# "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.
