- * New Objfile Event Hook:

- * Sometimes a GDB component wants to get notified whenever a new

- * implementations that need to know when symbols for the target
- * thread implemenation are available.
- *
- * The old way of doing this is to define a macro 'target_new_objfile'
- * that points to the function that you want to be called on every
- * objfile/shlib load.
-
- The new way is to grab the function pointer,
- 'deprecated_target_new_objfile_hook', and point it to the function
- that you want to be called on every objfile/shlib load.
-
- If multiple clients are willing to be cooperative, they can each
- save a pointer to the previous value of
- deprecated_target_new_objfile_hook before modifying it, and arrange
- for their function to call the previous function in the chain. In
- that way, multiple clients can receive this notification (something
- like with signal handlers). */
