20 # Define callbacks and load other libraries. This file is loaded relatively
21 # early, and before any other file we write ourselves. "load_lib" will
22 # find anything in the DejaGNU installation tree, or in our lib directory.
23 # "load_gcc_lib" will search the core compiler's .exp collection instead.
25 # The naming rule is that dg.exp looks for "tool-" and runtest.exp looks
26 # for "tool_" when finding callbacks. Utility routines we define for
27 # our callbacks begin with "v3-".
29 # libstdc++_* callbacks we don't define, but could:
30 # ..._option_help prints additional --help output
31 # ..._option_proc (--foo) process our own options
32 # ..._init (normal.exp) called once per test file
33 # ..._finish bracketing function for libstdc++_init
34 # ...-dg-prune removing output text, see top of system dg.exp
36 # Useful hook: if ${hostname}_init exists, it will be called, almost
37 # the last thing before testing begins. This can be defined in, e.g.,
38 # ~/.dejagnurc or $DEJAGNU.
