Again, it's been years and years. Right, which is why killing a.out entirely would have the unfortunate effect of also removing the OSF/1 compatibility on Alpha. If we are to support Alpha as an architecture at all, it makes sense to support the things people actually use it for. Now, personally I can live without it. I just don't like to see features removed without due consideration. -- Måns Rullgård From mboxrd@z Thu Jan 1 00:00:00 1970 From: =?iso-8859-1?Q?M=E5ns_Rullg=E5rd?= Subject: Re: [PATCH] x86: Deprecate a.out support Date: Mon, 11 Mar 2019 19:47:25 +0000 Message-ID: References: <20190305091904.GB8256@zn.tnic> <20190305122218.GD13380@bombadil.infradead.org> <20190305134347.4be2449c@alans-desktop> <20190305145717.GD8256@zn.tnic> <20190305173134.GE8256@zn.tnic> <20190305181138.GG8256@zn.tnic> <20190305181808.GH8256@zn.tnic> Mime-Version: 1.0 Content-Type: text/plain; charset=iso-8859-1 Content-Transfer-Encoding: 8BIT Return-path: In-Reply-To: (Linus Torvalds's message of "Mon, 11 Mar 2019 12:03:18 -0700") Sender: linux-kernel-owner@vger.kernel.org To: Linus Torvalds Cc: Matt Turner , Borislav Petkov , Alan Cox , Matthew Wilcox , Jann Horn , Al Viro , Thomas Gleixner , kernel list , linux-fsdevel , the arch/x86 maintainers , Linux API , Andrew Morton , Richard Weinberger , Anton Ivanov , linux-alpha , linux-m68k@lists.linux-m68k.org List-Id: linux-api@vger.kernel.org Linus Torvalds writes: > On Mon, Mar 11, 2019 at 11:08 AM Måns Rullgård wrote: >> >> The latest version I have is 5.1, and that uses ECOFF. > > ECOFF _is_ a.out as far as Linux is concerned. > > So Linux basically treats ECOFF as "regular a.out with just some > header extensions". > > We don't have any specific support for ECOFF. > > I _think_.
