GDB CVS won't build on OSF4.0's cc

[Alexandre Oliva]

This patch fixes it.  I'm checking it in as obviously correct.

More of the same...  Checking in...

Re: GDB CVS won't build on OSF4.0's cc

[Alexandre Oliva]

Another problem showed up while building gdbtk.  gdb/defs.h #includes
<stdarg.h>, but tcl/generic/tclInt.h #includes <varargs.h>, because
HAS_STDARG is not defined.

It turns out that the va_start macro defined in varargs.h ends up
overriding that of stdarg.h, so we call va_start with the wrong number
of arguments.

Since GDB assumes the existence of stdarg.h, I suppose this patch
would be acceptable.  Ok to install?

I'm not the maintainer of the file in question, but one of our long
term goals has been the elimination of PTR from the gdb sources.  I
think the fix should have been to change PTR in the definition to
void * rather than change the declaration to match the definition.

Oh, well.  Sorry about that.  I'll try to keep that in mind next time
I stumble across this kind of problem.

Alex, no. Sorry, but we are trying to get rid of PTR in the
gdb sources [as Kevin pointed out in another message].

Could you 'revert' these changes by changing the definitions to 
use void * and deleting the prototypes when they are not needed (everyone
of these can go, except for free_elfinfo, I think).

[see Andrew's patch: 
http://sources.redhat.com/ml/gdb-patches/2001-06/msg00077.html ]

Thanks and sorry again.

Elena

PS. I'll go through these files later and clean up some more of these.

Fixed as follows.  Not tested on all relevant architectures.  I'd do
that after next Monday's GCC snapshot, since I've been building GDB
along with GDB lately.  Ok to install?

Dunno.  I was just dumbly replacing PTR with void*, as requested.

Does anyone know?

IMHO, excess casting is evil, as it can mask programmatic errors.
However, if GDB standards don't frown on this, it's fine by me.

If memset is prototyped as taking a void *, this cast is unnecessary; the
C standard requires that the argument be converted appropriately due to
the prototype.  If memset is prototyped as taking a char *, this cast
neither hurts nor helps; the pointer has to be converted into a char *
anyway and that would be done by the prototype.

If memset isn't prototyped or has a K&R-style prototype without argument
types, then this could arguably help if pointers to different types of
objects were represented differently internally.  I'm a little skeptical
whether gdb supports such systems without proper function prototypes, and
I'd argue that this case is so insanely rare as to not bother worrying
about, particularly since gdb is now requiring ANSI C.

I've been systematically ripping those sorts of casts out of INN for a
while now.

Yes, I think we can safely get rid of these casts.
See a few line below, the call:

  memset (objfile->sym_private, 0, sizeof (struct coff_symfile_info));

Yes, but with the memset calls changes, i.e. remove the casts.

I don't expect any one to disagree.  Ever since GDB started assuming 
ISO-C, people have been quietly removing these redundant casts.

Guess its time to extend the GDB mantra: Macro's are bad, casts are 
evil, m'kay.

This one seems to have never been acknowledged.  Ok for 5.2 and
mainline?

Ok, here's an updated patch, that applies cleanly into mainline and
5.2 branch, and that adds two more PTR->void* fixes that slipped in
after my original clean-up.  Oh, and that removes the (void *) casts
in memset calls that I had introduced in my previous patch.  Ok to
install in 5.2 and mainline?  With this and the other 2 patches I
posted today (for gdb/defs.h and expect), gdb 5.2 builds successfully
with OSF 4.0's cc.

I don't know that this belongs in defs.h (definitly not without a big 
comment explaining the history :-).  As you note, gdb doesn't include 
tclInt.h, only GDBTK.  I suspect gdbtk/generic/gdbtk.h or autoconf is 
better?

It would be a silly use of autoconf, since gdb just assumes stdarg.h
is there.  As for its not including tclInt.h, it's true that gdb
itself does not, but some of the gdbtk files include tk, itcl and tix
headers that end up including tclInt.h.  Unfortunately, they include
gdbtk.h only after including such headers, so adding a define in
gdbtk.h would be too late.

I agree we should try to keep gdbtk as separate from gdb as possible,
but I thought this define would be ok, since gdb's configure already
has code to look for tcl/tk.  Anyway, here's an alternate patch that I
dislike a bit on the grounds that it doesn't make sure the problem
won't show up again in the future, and it won't trigger any warnings
should gdb proper ever drop the assumption that stdarg.h is present
(unlikely, but... :-)

Ok to install?  Verified to build with OSF4.0's cc.

OK, I think this is fine now, but you forgot one PTR in defs.h, see
below.

Check it in, thanks.

It was not forgotten, but rather intentionally left in.  Since some
compilers are picky about differences between PTR and void*, and there
still are a number of function definitions and declarations that used
PTR, I thought I wouldn't take such a bold step at this time.

Mainline and 5.2 branch?

I think build failures fixes qualify for 5.2. Is there a bug report
for this?

Great.

Other than the one that came with the patch posted to this mailing
list?  I don't think so?  Should I create one, install the patch and
then close it?  I'm not aware of such GDB policies :-(

I counted 4 or 5!  You should look at gdb/390, there may still be 
``issues''.

 > I'm not aware of such GDB policies :-(

I think people doing this are viewed in a positive light (however there 
isn't any strict requirement :-).

The rewritten web page reads:

> GDB has a Bug Database. It is used to track bugs (Problem Reports or PRs) and enhancements (Change Requests or CRs). In addition to problems encountered when running GDB, bugs include: errors or missing documentation; missing test cases; web changes; work in progress; dummy reports for fixed but unreported bugs; entries of not-a-bugs; and even adminstrivia.

There is also 294 (which is essentially a duplicate of 390).  Alex,
can you take a look? Maybe your configury test needs to be made a bit
more sophisticated.

bug 324 can be closed.  bug 183 is unrelated with the problem I
fixed, and I don't have access to Tru64 5.1 AFAIK to check.  I
couldn't find other related problems.

Oh, and don't forget there's that other patch for Insight to build on
OSF that is yet to be reviewed.

This is a totally different subject.  This patch is for a build error
on OSF1/DU/Tru64.  Both PRs you mention are about TOC problems on
AIX.

I never thought such a simple patch would take so long to get in (my
fault; I dropped the ball in revising the patch as requested for a
long while).  Anyway, when a patch is ready, I see little value in
creating a PR.  To me, it feels like pure overhead.  If you have a
different opinion, please enlighten me :-)

Sorry! Both Andrew and I were thinking of this other thread:

Are any of the priority==high bugs related to this (as opposed to the
minimal-toc) problem?

If your patch fixes 324, I guess you can just close it, and mention the PR
number in the changelog entry.

I'd need write access to the GNATS GDB database to do so.
