The i386 has been partially multi-arch'ed for some time now, but only
the bare minimum has been done. Therefore I decided to put some real
effort into it. I think I've tackled most of the difficulties, and
made some real progress. Unfortunately there are quite a number of
old targets that I'd really like to drop in this process. I made some
lists with targets: targets that are already working satisfactory,
targets that I intend to support (possibly with the help of others),
one target that's really redundant, and a few targets that I'd like to
obsolete. Please take a good look at that last look, and yell at me
if you can think of a reason not to obsolete any of those targets. If
I don't hear anything within the next few weeks they will be lost
forever :-).

These three should be identical.

Can this go? I think it is the old old Novell thing.

ChrisF would like the PE deleted! It's been bug reported.

I think this can go (or at least an attempt made).

Obsoleting os9kread is on the to do list as well.

OK, I just posted something to gdb-announce.

These three should be identical.
Not quite. i386-*-elf* uses a register numbering scheme for stabs
(stabs-in-ELF to be precise) that differs from traditional stabs used
for a.out and COFF.

Right now it's only supported as a target, and it was really trivial
to add. So I'll keep it.

Ah, well, it's basically identical to i386-*-aout* and i386-*-coff*.
The only "support" is the line in configure.tgt. I'll leave it to
Chris to decide what to do with it.

I'll leave it alone for now.

Yup!

I'll probably start making a real mess next weekend ;-). I hope it'll
be acceptable that some targets will be broken for a few days. I
don't think I can keep things compiling without resorting to one large
mega-patch.

Ah! So BFD could be built differently but GDB would be identical - like
the sh*-* target.
M'kay,

I have nothing to yell at you for.
