This didn't seem to work. I know I first tried doing it that way.

The code originates from config/i386/winnt.c. I supposed that what has
been in there for years should be sufficiently correct. I would guess
that, much like has been done in other places, replacing xmalloc by
ggc_alloc would be the way to go?

Why that? As long as special cases for gcc exist in these headers this
should be fine. And, given the structure of the NetWare headers (which I
can influence to a certain degree, but not in the sense of asking to
completely restructure them), using certain gcc headers will break. The
two ones I consider potential candidates for inclusion are float.h and
iso646.h, but stdbool.h and stddef.h unfortunately don't currently fit
in the remaining structure.

Also agreed.

Indeed, no. And I thought of unifying them into config/i386/. But the
(up to the 3.4 branch) pre-existing sources had them in this way,
despite there never having been NetWare on anything but x86. I'll move
them down, and in the unlikely case that we'll ever want to use them for
something else, this can still be adjusted/split accordingly.

Thanks for looking so closely at this, Jan

Because the C standard says a stand alone (free standing I think is
the correct term here) compiler must provide them.

stddef.h because we have our own defintion of offsetof which depends on the
compiler version you are using, pre 3.4, it is the normal offsetof macro that
everyone defines it as.  3.4.x it is special only for C++ and then for 3.5.0 and
above we have our own defintion so that the constants expressions can be constant
expressions.

Sure.

What, *specifically*, is the failure here?

It looks to me that if you have both HAS_INIT_SECTION and 
CTOR_LISTS_DEFINED_EXTERNALLY defined then libgcc2 should
do the right thing, i.e. nothing.

I think this one is likely fixed with CTOR_LISTS_DEFINED_EXTERNALLY.

This neither fits in the startup logic NetWare has
(__init_environment/__deinit_environment in netware-crt0.c, which can't
be used together with the crtstuff.c logic [NetWare has its own startup
code which calls out to these two functions], and libgcc2.c doesn't
account for this case) nor the section ordering one (the linker used
doesn't order sections purely by object file order, but uses the
MSVC/COFF-style approach of concatenating subsections according to their
name tag (following the separator character $).

That's the point: Other than with limits.h, gcc's stddef.h doesn't (and
generally can't) #include_next the system header (since that might not
exist at all).

OK, if get_identifier() always makes a copy... Again, I just modfied
pre-exisiting code.

As I said, I have only limited influence on what the NetWare libc
headers look like. There are far more severe standard violations in
there that I can't get them to correct...

I guess I don't care that much, since it's your own lookout if things
go wrong with some later version, but what breaks about gcc having its
own stddef.h and #include_next'ing the system header?

Yes it is.  Although I was just going to suggest freeing the 
malloced memory after creating the identifier.

Lets look at this part again:
+  newsym = xmalloc (1 + strlen (asmname) + 1 + 10 + 1);
+  sprintf (newsym, "%c%s@%d", FASTCALL_PREFIX, asmname,
  total/BITS_PER_UNIT);
+  return IDENTIFIER_POINTER (get_identifier (newsym));


It is too local to the function as we know that get_identifier will
always copy the string to a new char pointer it does not matter.

You have not answered this part yet, why are trying to violate the

You should probably be defining HAS_INIT_SECTION.  It doesn't 
mean *exactly* that .init/.fini sections are used; several other
platforms use this define with other startup mechanisms.

Hmm?  I think removing

         $(srcdir)/ginclude/stdbool.h \

is sure to be a mistake.  Indeed, I know for a fact that not

Do *any* of the files you added to config/ really belong there?
Do you actually plan on supporting anything besides x86?

re-establish NetWare as a supported (cross-only) target

[Jan Beulich]

[-- Attachment #1: Type: text/plain, Size: 403 bytes --]

This is to resurrect NetWare as a supported target. Test results have
been
posted to gcc-testresults (with this and the mentioned below auxiliary
patches applied).

Correct functionality implies the previously posted patches to correct
#pragma pack(), to support the preference of linking against a shared
libgcc,
and the section separator to indicate section fragments to be merged by
the
linker.
