/*
* New Objfile Event Hook:
*
* Sometimes a GDB component wants to get notified whenever a new
* objfile is loaded. Mainly this is used by thread-debugging
* 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). */
