[PATCH] Remove Vax Ultrix and VAX BSD support
- From: Pedro Alves <palves at redhat dot com>
- To: GDB Patches <gdb-patches at sourceware dot org>, eli Zaretskii <eliz at gnu dot org>
- Date: Fri, 17 Oct 2014 16:25:48 +0100
- Subject: [PATCH] Remove Vax Ultrix and VAX BSD support
- Authentication-results: sourceware.org; auth=none
Here's a patch that removes support for VAX Ultrix and VAX (old) BSD.
Is the NEWS bit OK? There are no mentions of Ultrix in the manuals,
other than in stabs.texinfo, but those should stay.
