obsolete directories in src tree: mmalloc, iwidgets, blt

obsolete directories in src tree: mmalloc, iwidgets, blt

[Steve Ellcey]

Overseers,

While looking through the source tree for uses of old (pre 2.5) autoconf
I have found 3 directories that appear to no longer be used; mmalloc,
iwidgets, and blt.  I was wondering if we should delete these
directories.

I checked with the insight list (see
http://sources.redhat.com/ml/insight/2006-q1/msg00111.html) about blt
and iwidgets and they seem to be ameniable to removing blt and iwidgets.
blt was never used by insight.  iwidgets might have been used, but if it
was it was five or so years ago.  I looked at some of the files under
both blt and iwidgets and there are no insight or gdb tags on any of the
files.

My understanding is that mmalloc is also no longer used but it does have
a lot of gdb tags on the files and it has been in use more recently.  At
the top level ChangeLog I find:

2005-02-08  Andrew Cagney  <cagney@gnu.org>

        * MAINTAINERS: Delete reference to dejagnu/ and mmalloc/ from the
        gdb/ section.  Update GDB's URL.

So I think that is when mmalloc stopped being used.  The dejagnu
directory seems to have already been removed but the mmalloc directory
is still there.

So, should these three directories (blt, iwidgets, mmalloc) be deleted?

My main interest is to be able to tell the GCC list that we can update
libtool because everything in the GCC and src trees is now using
autoconf 2.5 or later.  So if we want to leave these directories alone,
with the knowledge that they are no longer used, that would probably be
good enough for my purposes.  But if they are no longer used, maybe we
should just remove them.

blt was used at one stage by sid.  You might like to check if that's
still true.  We were using some of the specialised widgets in blt in
some of the visual components.

Thanks for the pointer.  I sent email to the sid email list and got a
reply that removal of blt would be OK with them.

Binutils does not use any of these, so their removal is fine by us.

Cheers

It stopped being used long before.  It continued to be checked out and
shipped until around then.

I think yes.
