[patch 1/2] Remove a.out NetBSD and OpenBSD targets

[patch 1/2] Remove a.out NetBSD and OpenBSD targets

[Jan Kratochvil]

Hi Mark,

as you suggested in
	Re: solib-sunos.c is broken
	https://sourceware.org/ml/gdb/2013-08/msg00085.html
	Message-Id: <201308210827.r7L8RStV017117@glazunov.sibelius.xs4all.nl>

going to remove the targets depending on solib-sunos.c.

I have verified all .o files referenced by removed .mh files are still in use
by at least one of the remaining .mh files.

You asked there to keep m68k OpenBSD ELF.  Its solib-sunos.o reference is
removed in the next patch.
	config/m68k/obsd.mh 
	m68*-*-openbsd*)        gdb_host=obsd ;;


Thanks,
Jan

I wanted to fix s/Removed hosts/Removed native configurations/ as I found
later such wording there from the past, I guess that is better / also OK.

Yes.

Re: [patchv3 1/2] Remove a.out NetBSD and OpenBSD hosta and targets

[Pedro Alves]

Should we add these to the "Configuration $host is obsolete"
case at the top of gdb/configure.host?

There's a bit of a problem here.  The removal of some of the -netbsd*
stuff will also remove support for some of the NetBSD ELF targets.
That should not happen.  So I think you should:

1. Drop the configure.tgt bit from this diff.  The removal of a.out
   support should only affect *native* builds.

2. Adjust the NEWS to only list the old OpenBSD/i386 and explicit
   NetBSD a.out bits.

OK, I see now that the targets support is indifferent for a.out vs. ELF.

One could additionally disable a.out targets (and permit their *elf
counterparts) but that would be needless limitation of GDB.

Not sure I understood, the NEWS file lists only the explicit hosts.

Re: [patchv4 1/2] Remove a.out NetBSD and OpenBSD hosta and targets

[Jan Kratochvil]

Hi Mark,

additionally I thought one can remove a.out support from *bsd-{nat,tdep}.c
files.  But then I found in sparcnbsd-tdep.c:

/* OpenBSD uses the traditional NetBSD core file format, even for
   ports that use ELF.  Therefore, if the default OS ABI is OpenBSD
   ELF, we return that instead of NetBSD a.out.  This is mainly for
   the benfit of OpenBSD/sparc64, which inherits the sniffer below
   since we include this file for an OpenBSD/sparc64 target.  For
   OpenBSD/sparc, the NetBSD a.out OS ABI is probably similar enough
   to both the OpenBSD a.out and the OpenBSD ELF OS ABI.  */
#if defined (GDB_OSABI_DEFAULT) && (GDB_OSABI_DEFAULT == GDB_OSABI_OPENBSD_ELF)
#define GDB_OSABI_NETBSD_CORE GDB_OSABI_OPENBSD_ELF
#else
#define GDB_OSABI_NETBSD_CORE GDB_OSABI_NETBSD_AOUT
#endif

OTOH there is even code for ELF BSD core files. Still the patch would probably
regress OpenBSD so just posting it here as is FYI without ChangeLog.

Right.

My idea was not to worry too much about the exact host triplets that
are no longer supported.  Most of these switched to ELF more than 10
years ago, and chances of somebody actually building a current GDB on
such a system are close to zero.  I'd just blacklist *-netbsdaout* and
start treating *-netbsd* as an alias for *-netbsdelf*.  But what you
did looks correct, so you probably should just go ahead with this.
