value correctly, since it forgot to lookup the correct value

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.

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

Hi Eric,
The attached diff file includes BUS_ISA fix for kernel since 2.4.23/
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.

_dl_debug_addr prior to checking if it was NULL.

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.

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.
