Subject: [PATCH v3 07/17] Remove remaining cleanup from gdb/breakpoint.c
Date: Wed, 23 Jan 2019 15:21:00 -0000	[thread overview]
Message-ID: <20190123152131.29893-8-palves@redhat.com> (raw)
In-Reply-To: <20190123152131.29893-1-palves@redhat.com>

From: Tom Tromey <tom@tromey.com>

In v3: remove the "have BKPT_CHAIN already discarded" comment too.

The remaining null cleanup in breakpoint.c does not seem to protect
anything, so remove it.

gdb/ChangeLog:
yyyy-mm-dd  Tom Tromey  <tom@tromey.com>
	    Pedro Alves  <palves@redhat.com>

	* breakpoint.c (create_breakpoint): Remove cleanup.
