where possible. This will also make ldso smaller.
However the patch touches all archs and I have only tested PPC and x86.

execution of ldso.
Added new asm for MIPS to be tested.
All arches should retest.

Add elf_machine_dynamic() and elf_machine_load_address() for
all archs. elf_machine_dynamic() replaces the #ifdef mess to
get at the GOT. elf_machine_load_address() is needed to execute
ldso directly, this is not complete yet.
I probably broke one or two archs(only tested PPC) so please
try and report problems. For a report to be useful you need
to enable __SUPPORT_LD_DEBUG_EARLY__ and __SUPPORT_LD_DEBUG__

Begin converting some big ugly macros to inline functions
instead

Hi it is me again.
This is the latest ldso patch. the NEW weak symbol handling works now
with a little special handling in _dl_find_hash(). You get to chose
if you want the new or old handling :)
There was 2 missing _dl_check_if_named_library_is_loaded() calls in _dlopen().
I then disabled the _dl_check_if_named_library_is_loaded() in dl-elf.c since
it is rendundant.
Question, why does some _dl_linux_resolver(), like i386, have 2 calls
to _dl_find_hash()? I think that is wrong, isn't it?
I really hope you can check this out soon ...

For sh64 we need implicit access to the symtab, primarily to get at the
->st_other value. This presently isn't possible, as PERFORM_BOOTSTRAP_RELOC()
is invoked as such:
PERFORM_BOOTSTRAP_RELOC(rpnt, reloc_addr, symbol_addr, load_addr);
while we can easily get the symtab_index value from rpnt->r_info, this still
doesn't buy us easy access to the actual table. As such, I've modified
PERFORM_BOOTSTRAP_RELOC() to take an additional SYMTAB argument. Most
architectures aren't going to care about this, but unfortunately we don't
have any other options for sh64.
The following patch fixes up the API for what we need for sh64, and updates
the other architectures appropriately.

out page alignment issues. As we we were assuming 4k pages, which
need not be the case...

and when using real functions. Make things be more portable by
providing a default C routine to locate the got.

III and me. I've been working on stripping out arch dependant stuff and
replacing it with generic stuff whenever possible.
