f2602cd538 Comment out the retrieval of a termination function from %g1. It is
doubtful this will ever be used by anything and rtld uses %g1.
Comment out references to _init and _fini for now too.

ee425bffeb Sparc64 ELF version of the C runtime support.
It tries to comply with the SCD 2.4.1 (and thus Sparc 64-bit psABI).

This is an amalgamation of the FreeBSD Alpha crt1.c and the BSD/OS Sparc
crt0.c (which the copyright reflects).

ae7c8a2bb8 * Bring back the guts of crt{i,n}.S. This allows C++ exceptions to work
when using the egcs and gcc-devel ports, along with GCC built from stock
public FSF sources.  With out this change, FreeBSD will be removed from
the list of systems GCC 3.0 must be evaluated on before release.  With
the effort some of us put into getting FreeBSD on this list, we should
not turn this effort into a waste, else we might not be worth fighting
for in the future.  (note that Alpha and IA-64 versions of crt{i,n}.S
are needed)

* Switch from our own crt{begin,in} to those created from GCC's crtstuff.c.
This will allow us to switch to DWARF2 exceptions in the future, along with
staying in sync with any future GCC requirements.

* Break out our ELF branding bits into a seperate file.  Currently this
is now included by our crt1.c files (since this functionality was part of
our native crtbegin.c).  Later crtbrand.o will be merged in the creation
of crti.o.

f6d15b87f8 This is step 1 in an effort to unify the start-up files for the
various architectures.  Now all the work is done in crtbegin.c.
It doesn't contain any assembly language code, so it should work
fine on all architectures.  (I have tested it on the i386 and the
alpha.) The old assembly language files crt[in].S are now empty
shells that generate no code or data.  They should not be removed
any time soon, because the various versions of gcc in src and ports
expect them to exist.

Next I will move crtbegin.c into a new common machine-independent
directory, and adjust the i386-elf Makefile to use that version.
After that I will adjust the alpha Makefile to use the common
version too.

c815a20cb2 Change our ELF binary branding to something more acceptable to the Binutils
maintainers.

After we established our branding method of writing upto 8 characters of
the OS name into the ELF header in the padding; the Binutils maintainers
and/or SCO (as USL) decided that instead the ELF header should grow two new
fields -- EI_OSABI and EI_ABIVERSION.  Each of these are an 8-bit unsigned
integer.  SCO has assigned official values for the EI_OSABI field.  In
addition to this, the Binutils maintainers and NetBSD decided that a better
ELF branding method was to include ABI information in a ".note" ELF
section.

With this set of changes, we will now create ELF binaries branded using
both "official" methods.  Due to the complexity of adding a section to a
binary, binaries branded with ``brandelf'' will only brand using the
EI_OSABI method.  Also due to the complexity of pulling a section out of an
ELF file vs. poking around in the ELF header, our image activator only
looks at the EI_OSABI header field.

Note that a new kernel can still properly load old binaries except for
Linux static binaries branded in our old method.

  *
  * For a short period of time, ``ld'' will also brand ELF binaries
  * using our old method.  This is so people can still use kernel.old
  * with a new world.  This support will be removed before 5.0-RELEASE,
  * and may not last anywhere upto the actual release.  My expiration
  * time for this is about 6mo.

5ae2733874 Call do_ctors() and do_dtors() using indirect calls through function
pointers.  The calls are in different sections from the functions
being called, and they can potentially be far away.  On a very large
program, the 21-bit displacement field of the BSR instruction
overflowed at link time.

to Dmitrij Tejblum <dima@tejblum.dnttm.rssi.ru> for pointing out
that it was the optimizer's removal of this code that caused make
world with -O3 to break.  With this change, make buildworld now
completes.

0738f6e0c3 Reverse the order of processing object files within an executable or
shared library when invoking global constructors and destructors.
For constructors, the object files used to be processed from first
to last; now they're done from last to first.  (Destructors are done
in the opposite order, as required by the C++ standard.)  This makes
us consistent with standard gcc and egcs compilers.  It also
eliminates ordering differences between dynamic and static
executables.

Bump the value of __FreeBSD_version to 400002 to reflect this
change.

bb2b869188 Move the code for the ".init" and ".fini" sections outside of a
C function so the compiler won't try to emit line numbers for it
with "-g", breaking the build.  This has the nice side-effect of
making crtbegin.o and crtbeginS.o a little bit smaller.

Remove "-Wno-unused" from the Makefile.  Replace it with "__unused"
on particular function and variable declarations.

f92bdbd010 Switch to using ".So" as the extension for PIC object files rather

naming conventions for dynamically loadable modules.

The "clean" targets continue to remove ".so" files too, to deal with
old systems.
