I've added a 'maintenance' branch on the official tree: 
  git://git.kernel.org/pub/scm/devel/sparse/sparse.git maint-v0.6.2

which contains a few fixup patches I think the Debian release should have.
It contains, the 'gensel' patch here above (not very important, it just fix
a warning), your patch for sindex.1 (same), the build fix for Hurd and
most importantly it contains a patch for a real bug making sparse crash:
  77f35b796cc8 ("generic: fix missing inlining of generic expression")

Thanks,

For the build failure on X32:
  /usr/include/x86_64-linux-gnux32/gnu/stubs.h:7:12: error: unable to open 'gnu/stubs-32.h'

Sparse should be called with '--arch=x86_64 -mx32' but the error
indicate that '__x86_64__' is not even defined, as if another
architecture was selected. Very strange.
I can't reproduce this here (nor in my old setup, nor in a brand
new reinstall of a x32 chroot).


The output of:
   env CHECK=./sparse ./cgcc -v -no-compile memops.c
should be:
  ./sparse -v --arch=x86_64 <lots of defines for floats> -mx32 --os=linux -gcc-base-dir /usr/lib/gcc/x86_64-linux-gnux32/10/ -multiarch-dir x86_64-linux-gnux32 memops.c

I absolutely don't see what can be wrong. But I wonder why it
happens first or only on memops.c and not on one of the file
listed earlier, for example allocate.c?

Ah yes, OK :)
I thought 'make selfcheck' was called.

Hmmm, I think that a corner of my mind was silently worried it

Not really.
Would it be easy to install it under the name 'sparse-sindex' or
'sparse-index'?

One thing I would like (in some future release) is to split
the sparse package at least in 2:
* one with sparse itself
  - it has no dependencies (except the libc, a compiler compatible
    with gcc and GNU make for the build)
  - maybe cgcc should be included in the package too (which would
    add a dependency on perl)
* one with the others tools
  - but maybe it would even be better to the big ones in their
    own packages with their own dependencies)
But this would not really solve the problem here.

Renaming of sindex was an option for me, but since you have a plan
to split the package anyway, then I think it's better to do so. I tried to
use the libsparse.a and it looks like it works fine [1].

I spoke with Oleg Nesterov and he also does not mind moving this utility
to a separate repository.

Oleg pointed out to me that my email is not entirely clear :)

My email does not mean at all that I moved the utility to a separate
repository. I made a proof-of-concept.

Don't get me wrong, I don't mind renaming the utility. This is a good
short term solution but to be honest I don't like the name 'sparse-sindex'
because it is very long. Can we think of something shorter ?

Also, could you tell us more about your plan for future releases ?
How do you plan to split the repository ?

I think it would be better to rename it in any case, whatever you and Luc
decide. We do not want the naming conflict, imo.

Just in case, I'd personally prefer to keep sindex in sparse's repository,
but of course I won't argue if you guys decide otherwise.

me too ;)

> Can we think of something shorter ?

I can't. May be just "dissect" ? But I agree in advance with any name.

Oleg.

Ah sorry, it's just a misunderstanding. The context of my email wasn't
very clear. But no worries, I have absolutely no intentions to split
the repository (that would be very annoying for everybody). I was only
talking about, maybe, in some future, split the *package* at distro
level. For example, currently Debian has already 2 packages for sparse:
one, called 'sparse', with almost everything, and another one only
with 'test-inspect', called 'sparse-test-inspect'.

In any case, I don't have any precise plan, and distro packaging is
anyway something to be decided by the distros. So, if anything will
done in this direction, it will be done in collaboration of the distros
and anyone involved.

For the name, I'm also don't like 'sparse-sindex', but it would just
have been an easy way to avoid the name conflict in Debian packages
(I understand that no such conflict exist with Fedora because
'biosquid' only exists for Debian).

I also think 'sparse-sindex' would be a bad name for anything
but this 'very-short-term-solution-for-this-package'.

Yes, of course. Propose anything. You're the author of this tool,
as such I consider that you have full moral rights on it, including
its name.  It's really up to you.

Oh my ... You are asking to come up with a new name for a person whose
fantasy is the same as that of a stone :)

I like Oleg's idea. Let's call the utility 'dissect' if it's not already
in use.
