            Bug ID: 95294
           Summary: [vax] Convert the backend to MODE_CC so it can be kept
                    in future releases
           Product: gcc
           Version: 10.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: glaubitz at physik dot fu-berlin.de
                CC: martin at netbsd dot org
  Target Milestone: ---
            Target: vax-*-*

This is a tracker bug for the convert the vax backend from CC0 to MODE_CC s=
o it
can be kept in future releases as there has been interest raised on the
NetBSD/VAX mailing list:

See: http://mail-index.netbsd.org/port-vax/2020/04/16/msg003460.html

For the background of the CC0 transition, see:

> https://gcc.gnu.org/wiki/CC0Transition

I will be using this bug report to create a bounty on BountySource.com.

We have already successfully funded such a conversion for the m68k backend,=
 see
#91851. Another campaign is ongoing for the avr backend, see #92729.

To test the backend, the emulator SimH can be used to install the VAX port =
of
NetBSD.

For that matter, a test image has been provided by John Klos:

> http://mail-index.netbsd.org/port-vax/2020/04/18/msg003481.html

There is also a generic howto which explains how to set up and install
NetBSD/VAX inside SimH:

> http://www.netbsd.org/ports/vax/emulator-howto.html

SimH is available for immediate installation in openSUSE, Ubuntu, Debian and
Fedora.

Alternatively, SimH can be obtained from the upstream project:
