I propose that the following targets be marked as unsupported in the
binutils 2.16 release, and be removed from mainline.
All non-BFD_ASSEMBLER gas targets. ie. the following, I think:
a29k-*-*
h8300-*-rtems*
h8300-*-coff
h8500-*-rtems*
h8500-*-coff
i960-*-bout
i960-*-coff
i960-*-rtems*
i960-*-nindy*
i960-*-vxworks5.0
i960-*-vxworks5.*
i960-*-vxworks*
m68k-*-vxworks*
m68k-ericsson-ose
m68k-*-sunos*
m68k-motorola-sysv*
m68k-bull-sysv3*
m68k-apollo-*
m68k-*-sysv*
m68k-*-coff
m68k-*-rtemscoff*
m68k-*-hpux*
m68k-*-linux*aout*
m68k-apple-aux*
m88k-*-*
or32-*-coff
sh-*-coff*
sh-*-rtemscoff*
tic80-*-*
vax-*-netbsd*
vax-*-bsd*
vax-*-ultrix*
w65-*-*
xscale-*-coff
z8k-*-* Christian, please update z8k to use bfd!
Dead and/or maintainerless targets.
d10v-*-*
d30v-*-*
dlx-*-*
i370-*-*
i960-*-*
m88k-*-*
mn10200-*-*
msp430-*-*
openrisc-*-*
or32-*-*
pj*-*-*
*-*-linux*aout*
*-*-linux*oldld
I'd like to add more targets to this list. Suggestions welcome. :)
Remember, if your favourite target happens to appear on this list, it's
not cause for heartburn. It's a call for action of the coding variety
as distinct from the political variety. ie. Step up and offer to
maintain the code rather than lobby to try to keep targets out of this
list. If you're a user of one of these targets, but don't feel capable
of maintaining a target, then you are very likely better off using an
older release of binutils. You might think that a newer binutils
release has more features and bug fixes than an older binutils. That
should be true for the well maintained targets, but targets that don't
have a maintainer are likely to have _more_ bugs than an older release.
Fixing bugs in one target can introduce a regression in another target.
Some of the targets I put in the dead/maintainerless list are fairly
new. I put them on the list simply because the original contributor
didn't put their name in binutils/MAINTAINERS. Please fix..

vax-*-netbsdelf* is a BFD_ASSEMBLER target.
Hence it should not be removed.

Work is being done to bring this up to date, see

Right. That '*' matches more than I meant. If I listed cpu-*-netbsd*
as slated for removal, then I should have excepted cpu-*-netbsdelf*.

Good. However, work in progress isn't enough to save m88k, I'm afraid.
m88k is currently a non-BFD_ASSEMBLER target, and I want to rip out all
the generic gas support for non-BFD_ASSEMBLER. I suppose we could keep
the m88k backend files on CVS head if the person working on m88k wanted,
but m88k-coff would no longer configure or build.

Hi Alan,
I propose that the following targets be marked as unsupported in the
binutils 2.16 release, and be removed from mainline.
What do you mean with "removed from mainline" here? These targets
from your list:
m88k-*-*
vax-*-netbsd*
vax-*-bsd*
vax-*-ultrix*
are still fully supported by me in GDB, and support for them shouldn't
be removed from bdf/ and opcodes/.
Also putting my OpenBSD hat on, vax-*-elf is somewhat important to us,
but from your reaction to Matt Thomass's mail you don't intend to
whack that.
Mark

I want to kill all non-BFD_ASSEMBLER gas targets, to reduce the
maintenance burden, and allow BFD_ASSEMBLER gas targets to be cleaned up
without worrying about breaking the old code. That will mean the
generic support code in gas for non-BFD_ASSEMBLER will disappear from
mainline. Whether the corresponding tc-* files disappear or not doesn't
matter so much, but I favour complete removal. You won't be able to
build these gas targets until they are converted over to use BFD.
More generally, I think we should remove targets that don't have active
maintainers listed in binutils/MAINTAINERS. Again, this is simply to
reduce the maintenance burden. Occasionally when making a global
change, I'd like to be able to email someone and say "xyz has changed,
please fix it for your target", rather than having to dig through some
crufty backend code myself.

OK, I guess that's reasonable. Please list yourself as a maintainer
in binutils/MAINTAINERS!

No.

Fair enough. Removing the tc-* files makes sense; people can always
get them from the attick or previous releases.

OK, I guess that's reasonable. Please list yourself as a maintainer
in binutils/MAINTAINERS!
I've added myself as m88k maintainer. I'm not too familliar with the
architecture, so if someone else steps up, I'll be perfectly happy to
step down.
The binutils/MAINTAINERS list already lists Jason R Thorpe as VAX
maintainer, so I didn't add myself there. I suppose Jason is mostly
interested in vax-*-netbsdelf* and not with the old a.out
vax-*-netbsd* stuff. Jason, if you want me to be co-maintainer for
the a.out stuff, please drop me another mail.

This zaps non-BFD_ASSEMBLER gas targets, with the exception of z8k which
Christian is in the process of converting. I'll commit tomorrow.

Umm, yes. I had it once already working but got distracted.
It needs some major cleanup and update to current HEAD, but I hope I can
finish it by next week.

Yes, set bfd_gas=yes in configure.tgt, then fix what breaks. Compare
target object files before and after..
