d00f222c77 Use the new machine-independent versions of crtbegin and crtend
from the "common" directory.

As a side-effect, this also fixes a bug in the ordering of global
constructors and destructors on the Alpha.  See revision 1.3 of
"../common/crtbegin.c" for details.

a15d1eb9f1 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.

0eac6bbc67 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.

d790b6b749 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.

change.

the executable file, so it will work for both a.out and ELF format

Add a bootstrap mode so that non-rtld versions of these objects can

c5a6510dda Sharing the crt sources with i386-elf wasn't too successful. The crti
asm code didn't link the way it was supposed to and the calling convention
for the entry "function" turned out to be very different. On alpha
it's a true function, but on i386 it's a fudge. Blech.

So jdp suggested keeping separate sets of source and avoiding lots
of #ifdefs. These files are based on his i386-elf code, with crt1.c
borrowing code from NetBSD's crt0. The copyright reflects that.

Complicating matters, the code turned out to be difficult to bootstrap
build using NetBSD tools. To compile against the FreeBSD rtld header
requires FreeBSD specific headers, but these can't be installed until
the tools are built, and they can't be built without the FreeBSD crt
objects. Anal retentive. So I introduced a HAVE_RTLD #define that isn't
set during the build process until all the tools are built and the
headers installed.

4538098d0b Move the trampolines for dlopen and related functions from crt0.o
into libc.  This reduces the size of every dynamically linked
executable by 248 bytes, and it reduces the size of static executables
by a lesser amount.  It also eliminates some global namespace
pollution.

With this change in place, the source for dlfcn.h should probably
be moved to "/usr/src/include".  I'll save that for another day.

Compatibility note:  Programs which use dlopen, if compiled on
systems with this change, will not run on systems with a libc from
prior to this change.  Very few programs use dlopen, so I think
that is OK.

72875e2a08 Declare the constructor/destructor linker sets as extern rather than
common.  Add one do-nothing element to each set.  This ensures that
the linker realizes that they are linker sets rather than simple
commons, and makes it possible to link c++rt0.o into every shared
library regardless of whether it is a C++ library or not.  Without
this change, the constructors and destructors in the main program
could be executed multiple times.

This change is going to make it possible to get rid of the
CPLUSPLUSLIB makefile variable once and for all.  It is a piece of
the solution to PR gnu/3505 (gcc -shared).  Finally, it fixes a
heretofore unreported bug:  If CPLUSPLUSLIB was set in a makefile
for a C++ shared library that had no static constructors or
destructors in it, then the main program's constructors and
destructors would be executed multiple times.

longer necessary, now that there is guaranteed to be at least 2

83a650d90c Check the count in the first word of __CTOR_LIST__ before executing
the loop that invokes the static constructors.  That makes it safe
to link c++rt0.o into any shared library, even one that does not
have any static constructors.  Formerly, doing that would cause a
bus error.  If the library has no static constructors, __CTOR_LIST__
comes out as a simple 4-byte COMMON region, and it does not have
the usual NULL word that terminates the list of constructors.  This
caused the old code to "call" a garbage address via the non-existent
entry __CTOR_LIST__[1].

The analogous code that invokes the static destructors was already safe.

This change is fully backward-compatible.

1) Do dependencies.
2) Install all appropriate links to manual pages.
3) Install header file in `beforeinstall' like all the rest.
4) Install header file only if changed.
5) Install object files only if changed.

6da3ef3223 Change ld.so to correctly load dependant libraries for dlopen and unload them
on dlclose.  Also correctly call constructors and destructors for libraries
linked with /usr/lib/c++rt0.o.
Change interpretation of dlopen manpage to call _init() rather than init()
for dlopened objects.
Change c++rt0.o to avoid using atexit to call destructors, allowing dlclose to
call destructors when an object is unloaded.
Change interface between crt0 and ld.so to allow crt0 to call a function on
exit to call destructors for shared libraries explicitly.

These changes are backwards compatible.  Old binaries will work with the new
ld.so and new binaries will work with the old ld.so.  A version number has
been introduced in the crt0-ld.so interface to allow for future changes.

0de4aa5096 Add (#ifdef'ed by STARTUP_LOCALE) following line to crt0.c
(void) setlocale(LC_ALL, "");

It will be easiest way now to make national chars available
for all ctype-oriented programs at once by simple:

setenv LANG Your_National_Charset

Default case (without "LANG" environment
variable) will be fully ANSI compatible (got "C" locale).

If "LANG" variable present, extention becomes active.

Effect of this extention is great: in one time all ctype
oriented programs can accept/print national characters
without any touching source/binary code, it is big win, IMHO.

This method is fully compatible with ISO8859-* and russian koi8-r
too (in general -- with all 8-bit character sets). I think
it is very useful.
I got this idea from Xenix locale implementation.

This extention is even never compiled in, unless you set
	setenv STARTUP_LOCALE
before rebuilding crt0.c or corresponding variable in /etc/make.conf

e1f08fe22b Remove dead code. gmon stuff is now done better in libc/gmon an
<machine/profile.h>.  The old version was writing an incomplete
header without the profrate field that is necessary to handle the
current faster profiling clock.  The counters that are where the
the profrate should be are usually 0 and gprof converts a profrate
of 0 to hz so the old version gave times too large by a factor of
profhz/hz = 10.24.

This fixes the problems Warner's having with ctors not being called
again with the latest round of ld changes and updates the file-names to what
Paul is using now.

The name change will not affect anything as we are not (yet) using it.
