# 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.
