- Subject: Remove toplevel.c:default_debug_hooks
Hi,
unless I missed the obvious, this static variable is assigned but never used.
This patch removes it as well as the code that assigned it.
I was able to rebuild gcc with this patch applied.
Ok for mainline ?
Tristan.

* toplev.c (default_debug_hooks): Remove this variable.
(process_options): Remove assignments to default_debug_hooks.
