Remove obsolete Solaris 8 support

Remove obsolete Solaris 8 support

[Rainer Orth]

[-- Attachment #1: Type: text/plain, Size: 5162 bytes --]

Since even extended support for Solaris 8 ends by March 31st, this patch
removes Solaris 8 support from mainline.  Given that extended support
for Solaris 9 lasts until October 2014, I guess that will remain in GCC
for at least one major release.

Again, I don't expect the patch to be controversial, but a few issues
bear mention:

* Although libgcc/config/sparc/sol2-unwind.h could be simplified quite a
  bit, perhaps we could go further: I wonder if the remaining nframes = 2
  case really applies to Solaris 9.  If not, one could massivly simplify
  this code.

* As in the IRIX case, I wonder if removing Solaris 8 support from libgo
  is a good idea while it still is supported on the 4.7 branch.

* In libstdc++, all checks for the presence of overloads can be replaced
  by hardcoded values.  This also allows __CORRECT_ISO_CPP_MATH_H_PROTO2
  to be removed and to drop the `1' in __CORRECT_ISO_CPP_MATH_H_PROTO1.

* I haven't yet checked if the Solaris references in
  libstdc++-v3/config/io/basic_file_stdio.cc are correct or also apply
  to newer versions.  This can probably wait for a later time.

* libstdc++-v3/doc/xml/manual/internals.xml still has various references
  to older Solaris versions.  I haven't touched those.

Bootstrapped without regressions on {i386-pc, sparc-sun}-solaris2.{9, 10, 11}
(Solaris 9/SPARC still running).  Ok for mainline if that passes (though
I guess I don't need approval for most of these changes)?

Thanks.
	Rainer

As with the Irix 5 changes, just send the libgo patches to me rather
than committing them directly to the repository.  Thanks.

One of the nice things about gcc is that gcc usually still works, long after a vendor has abandoned a machine.  I rather like that gcc will just work, unlike vendor software, which often says, please buy a new machine.  One doesn't have to remove support in gcc for something, just because a vendor doesn't support it.  That said, truly crufty things, should go.

No need to tell me, that's why I've been keeping the IRIX and OSF ports
going for so long, sort of like an OS archaeologist :-)  But both for
those and Solaris 8, the time has come where maintaining them is more
trouble than it's worth, as can be seen by the contortions I had to go
through to even find a machine still capable of running Solaris 8/x86.

I agree.  If it's not causing a serious maintenance issue, I see no
reason to remove it.

It does, unfortunately: Solaris 8 is even worse wrt. to C99 and POSIX.1
conformance than Solaris 9, especially in the areas of TLS and thread
support, as I've found the hard way during the GCC 4.7 cycle.  There are
all sorts of quirks, and the OS is now 12 years old.  I see better ways
to spend my (volunteer) time.

Personally, I'd be in favor of removing any target for which no test
results have been posted for the last, say, 2 GCC release series.
Otherwise there isn't any measure for the quality for such a target.
There've been GCC release series where a complete port failed to
build...

Ciao!

The nice thing is, anyone that disagrees with you, will step forward.  :-)  Notice, I didn't disagree with you...  I was only railing against the idea that we remove support, simply because a vendor did.  In this case, we're removing support, because it is more trouble than it is worth, which makes for a fine reason to remove support.

Here it is, with the same caveat as for the IRIX 6.5 removal.

If we are, we'll never learn if this code is needed on anything beyond
Solaris 8 and keep this cruft around basically forever.  I'll at least
try a bootstrap with the nframes = 2 code ripped out with Solaris 9 FCS
libc and libthread (and of course the whole rest: latest Solaris 9, 10
and 11) and see if anything breaks.

So what?  This file is a big kludge and there is no value whatsoever in it 
being elegant or particularly readable or even efficient.

what about applying the following cleanup (completely untested):
