Here is the cleaned up laze reloc patch.
Summary:
- Minor cleanup.
- disable the "if (finaladdr <= 0x01fffffc || finaladdr >= 0xfe000000)"
test since it almost never triggered.
- Optimized the lazy relocs handling.

Would be great if you could commit ASAP.

Jocke

Eliminate separate passes for _dl_copy_fixups() and _dl_fixup(), and
do both operations in a single pass.

Fixup silly typo

Patch from Joakim Tjernlund:

Removed R_PPC_NONE and R_PPC_REL24 as these does not seem to be used.
Corrected R_PPC_ADDR32 and R_PPC_JMP_SLOT

Patch from Joakim Tjernlund to get rid of an annoying warning.

Hi Erik

I have had some fun trying to optimize memcpy, memset and memmove for
PPC. There are only boot tested, but I don't expect any problems :)

Read the comments in powerpc/string.c for more info.
Patch is relative to libc/string

Kind regards,

Hi Erik

I have corrected a bug in uClibc/libc/inet/resolv.c in function
__dns_lookup(). Have attaced a txt file with my diffs regarding to
uClibc 0.9.26.

If two nameservers are included in /etc/resolv.conf and the first one is
wrong and the secondary is correct the algorithm never
looked up the secondary one. Please review my diff and feel free to
submit the patch onto your CVS.

If reading manual page resolv.conf(5) under nameserver and how the
algorithm should work the previous dns_lookup did not fully followed
that.

Regards

Hi again

I have done some serious clenup of powerpc/elfinterp.c

- Make it look more like glibc.
- Performance modifictions.
- Fixed a few bugs in _dl_do_reloc(). These seem not to have affected
anything, but this how glibc do it.

Some minor debian junk I had sitting in my tree

Sort all the files

ignore host binaries

Split up syscalls.c, since it had grown to be quite large and ugly.
-Erik

Add poll

Move poll to its own file, rather than being only half in its own file

Massive formatting cleanup, making it easier to parse

Erik is an idiot

support building the uClibc utils for the host system...

As noted by Doru Petrescu, there was a spurious line that was using
_dl_debug_addr prior to checking if it was NULL.

Paul Mundt writes:

The current behavior of the powerpc boot1_arch.h seems somewhat broken.
Currently room is made on the stack pointer for the link register, but the link
register is never actually pushed onto it. glibc bears the following comments:

/* Call _dl_start with one parameter pointing at argc */
mr r3,r1
/* (we have to frob the stack pointer a bit to allow room for
_dl_start to save the link register). */

followed by the -16 add to r1. Despite the fact that r1 is modified, the link
register is never actually pushed onto r1, thus the adjustment is completely
superfluous.

There's two possible fixes for this, either saving the link register in the way
that glibc does, or getting rid of the r1 adjustment. As I'm not sure if saving
the link register will actually break the _dl_boot2 callin, both options will
probably want to be played with.

The following bit of inline assembly in the attached patch builds cleanly for
me with gcc 3.3 on darwin, but I'm not able to test it any further beyond that.

Try this path. It fixes the recent ldso problems for me on my mpc860 board.
You should be able to use ldso without the dcbx patch to the kernel now.

Please report back.

Jocke

Add __data_start needed by boehm garbage collector, in turn needed by libgcj.

Prevent runaway asserts, which can happen if there's a problem with
stdio or locales.

We need to link with libgcc.a when creating shared libs, in order to
avoid problems 'hidden symbol' problems. Also handle -lfloat for the
soft-float arm case.

s/UCLIBC_HAS_MMU/ARCH_HAS_MMU/g

Fixup selection of endianness, since select does not work on choice
items, we have to declare what endianness cpus are capable of supporting
and work using dependancies.

Minor updates from linux 2.6.1

Link with libfloat if necessary.

Make sure we remove -fomit-frame-pointer from the ldso build. It's
inclusion will cause the loader to crash when jumping to the application.

The reason is due to the START macro having a "leave" instruction included
to fixup the stack before starting the app.

Include missing errno.h header (as noted by Alan Hourihane).
Fix uninitialized pthread mutex used to lock the list of aligned
memory blocks.
