hide the wrapper in with the debian stuff

Update docs in preparation for release

kill mention of the wrapper

For now, disable the iconv utility

Removing those instr. comes with a very big performance
penalty. To flush the dcache you will have read up to 8KB
dummy data and to invalidate the icache you will have to
execute up to 16KB nops. I don't know of any other way from
user space.

hmm, actually I think it will work reliable to perform a
store to the same page(s) as the dcbst/icbi will act on. That
way you will make the DTLB Error happen(if any) prior to the
dcbst/icbi. The worst thing that can happen then is a regular
DTLB Miss and that works for dcbst/icbi.

You will have to lookout for if dcbst/icbi crosses a page
boundary. Then you will have to perform a store to both
pages.

Hi again

I think I know what the problem is. The
PPC_DCBST;PPC_SYNC;PPC_ICBI;PPC_ISYNC sequence is executed
even if no modification has been done i some cases:

_dl_linux_resolver(), the last else has no store for insns[0].
these is a insns[1] = OPCODE_B(delta - 4) that
does not have a PPC_DCBST.

_dl_do_lazy_reloc(), for R_PPC_NONE there is no store.
for R_PPC_JMP_SLOT there is a
insns[1] = OPCODE_B(delta)that does not
have a PPC_DCBST.

_dl_do_reloc(), for R_PPC_COPY there is no store.
for R_PPC_JMP_SLOT there is a
reloc_addr[1] = OPCODE_B(delta) that does not
have a PPC_DCBST.

_dl_init_got(), I THINK that the
PPC_DCBST(plt);
PPC_DCBST(plt+4);
PPC_DCBST(plt+8);
PPC_SYNC;
PPC_ICBI(plt);
PPC_ICBI(plt+4);
PPC_ICBI(plt+8);
PPC_ISYNC;
is off a bit. The address range does not match the sum
of the plt[] and tramp[] address range.

# And then later added the comment:


I think that the tramp[] part should be included in the
PPC_DCBST/PPC_ICBI sequence. Then you have to add entries for
plt+12 and plt+16. If the tramp[] part should be excluded,
then all is well.

Fix up several errors related to filename length and errno that
showed up while running the latest LTP testsuite.

Add some basic cvs usage info

Sigh. I forgot to define INSTALL which, understandable,
broke the install target

Add clock_gettime() submitted by Justus Pendleton <uc@ryoohki.net>.

remove some junk I added while debugging

It is remotely possible the utils might even compile this time
around...

Begin converting the client utils

Revert change 1.26, which breaks everything. :-(

Sigh... I wasn't checking if the gid field in a group line actually
contained a digit. Also adjust a comment.

s,(RUNTIME_PREFIX)/,(RUNTIME_PREFIX),g

s,(DEVEL_PREFIX)/,(DEVEL_PREFIX),g

Add a utility macro.

Oops... don't need recursive mutexes.

Rewrite the pwd.h, grp.h, and shadow.h functions (except lckpwdf/ulckpwdf).

Add in aliases provided by the non arch specific implementations

Dear Erik,

We downloded uClibc lattest version from the CVS. Still there are some
minor problems with extra/Configs/Config.e1

You have actually set ARCH_HAS_C_SYMBOL_PREFIX to NO which is not
correct for our architecture. Please apply the patch that will fix the
problem.

Best Regards,

- George

P.S. Patch also removes some irritating comments we have added in the past.

A few debugging cleanups

The curse of cut-n-paste

Add some initial x86 string optimizations. These make no attempt to use nifty
things like mmx/3dnow/etc. These are not inline, and will therefore not be as
fast as modifying the headers to use inlines (and cannot therefore do tricky
things when dealing with const memory). But they should (I hope!) be faster
than their generic equivalents....

More importantly, these should provide a good example for others to follow when
adding arch specific optimizations.
-Erik

Remove erroneous trailing semicolon.

Fix a misnamed array

tiny cleanup

Rework the powerpc lib loader to better match the other architectures

Rip the guts out of the dynamically generated sysconf.c, and live with a simple
static version. This will need further work later on, but should do the job for
the time being,

last but certinaly not least, kill off initfini.c
