joerg | Drop TLS variant checks, emutls is enough for VAX and Sun2.

joerg | Implement __cxa_thread_atexit and __cxa_thread_atexit_impl. This
functions are used for destructors of thread_local objects.
If a pending destructor exists, prevent unloading of shared objects.
Introduce __dl_cxa_refcount interface for this purpose. When the last
reference is gone and the object has been dlclose'd before, the
unloading is finalized.
Ideally, __cxa_thread_atexit_impl wouldn't exist, but libstdc++ insists
on providing __cxa_thread_atexit as direct wrapper without further
patching.

Remove __P()

joerg | Pass down ELF Auxillary Vectors for static NetBSD binaries too.
Rename __libc_init to _libc_init and call it explicitly from CSU code.
This enforces the constructor run order for newly linked programs.
Keep it as constructor with run-once semantic for binary compatibility.
Implement dl_iterate_phdr for statically linked programs.
This material is based upon work partially supported by
The NetBSD Foundation under a contract with Joerg Sonnenberger.

skrll | Only do the __libc_init hack in libc, i.e. remove it from ld.elf_so.
This fixes hppa ld.elf_so by reducing the number of PLABELs required to
the number before the hack was applied.
Hi Joerg!
|
| 1.12 |
| 28-Jun-2010 |
joerg | Ensure that initfini.c is referenced by exit.c. The start up code has to
reference the latter as a return of main() results in a call to exit(3),
so this ensures that the libc constructors are run for statically linked
programs. Fixes PR 37454.

| 30-Oct-2007 |
skrll | branches: 1.11.12; 1.11.20;
Build a local copy of exit that doesn't call __cxa_finalize. It's not
needed and drags in a lot of libc via free.

| 07-Aug-2003 |
agc | branches: 1.10.22;
Move UCB-licensed code from 4-clause to 3-clause licence.
Patches provided by Joel Baker in PR 22280, verified by myself.

| 1.9 |
| 01-Mar-2003 |
thorpej | Rewrite atexit(3), and add support for __cxa_atexit()/__cxa_finalize(),
as specified by the C++ ABI for Itanium. Despite the ABI document's name,
many of the items in it are implemented for other architectures.
See the following URL for a reference:
http://www.codesourcery.com/cxx-abi/abi.html#dso-dtor
Fixes lib/18379 (from Joel Baker).
