X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=8b1c364c146fc5a73311a434f8f6eecf3e83685b;p=binutils-gdb.git

convert to_remove_mask_watchpoint

2014-02-19  Tom Tromey  <tromey@redhat.com>

	* target-delegates.c: Rebuild.
	* target.c (target_remove_mask_watchpoint): Unconditionally
	delegate.
	* target.h (struct target_ops) <to_remove_mask_watchpoint>: Use
	TARGET_DEFAULT_RETURN.
