till I properly finish the next step in my evil plan.

Hello Erik,
My patch adding ARM assembly soft-float routines to gcc also changes the
default FPA float word ordering for the saner VFP word ordering which is
also the order anyone would expect on a little endian machine.
Problem is that uClibc curently hardwire floats to big endian (FPA) ordering
in all cases.
Please consider the attached patch to fix this problem.

Hi again
All dltest* and test* programs pass for me.
uClibc ld.so resolves according to the OLD weak symbol handling.
I have tried to use the new scheme as well, but that segfaults in all
cases but test3.

to make it easier to treat it specially while not bothering the
rest of the code with the same constraints.

'__kernel_old_dev_t'. And of course there is no good way to know
which is in use except checking linux/version.h. Grumble.
This is rather lame, but for now, define __kernel_old_dev_t to be
the same as __kernel_dev_t. This will want to be revisited soon.

Hello,
the attached patch fixes ldso compilation on sparc-linux (at least with
sparc32 userland). It was made against uClibc 0.9.21, but it's still OK
with 0.9.26.
There were three problems:
- missing __NR_getpid definition
- conflicting prototypes in elfinterp.c
- syntax error (missing semicolon) in ldso.c
With this patch shared libraries and ldso can be built on sparc.
It contains also ldso.c syntax fix for m68k - there was the same
mistake two lines earlier; but I didn't test build on m68k.

I still don't have a good handle on why and when the different
scope values should be used.

add sh/sh64: ABORT_INSTRUCTION definitions
|
|
Here are some simple fixes for things that broke for PPC with
the recent syscall cleanup. I am not sure they are correct but
they seem pretty trivial.

Boredom got the better of me, here's strlen() for sh64..

This works, but I discovered something "funny". For all
relocs but COPY you can use scope instead of scope->dyn->symbol_scope
and it is much faster to do that. Search for "Funny" in the patch
to see what I mean. Probably I probably broke something, please let me
know if it works for you too.
I think I am done with ldso now. Has been fun and I hope to
actually use uClibc/busybox soon in a project.
Ohh, there is one thing left, double sized PLT entries, but maybe these
aren't needed in uClibc?
Sweet dreams

_dl_parse_lazy_relocation_information() and _dl_parse_copy_information()
so they are all consistant, allowing for future consolidation.
Trim some trailing whitespace as well.

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.

do both operations in a single pass.

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

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
Imre Sunyi

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.
