| # "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. |
