Hi Erik,

I added the FPU support for the setjmp/longjmp stuff.

This patch also moves the code from the bsd*.S files to the setjmp.S file, so
we can use simple branch instructions instead of referencing over the
.GOT/.PLT section. This makes the PIC code much easier, smaller and faster.
(The idea comes from the SPARC target)

Bye Stefan

since uclibc-0.9.16 I have to specify -fpic during _link_-time or else
I get an error from the dynamic linker when I load shared objects. Patch
is appended.

I noticed that dlclose() does not work since libraries loaded with
dlopen are not marked as "loaded_file". This breaks apache with dynamic
modules. I append a small fix against uClibc-0.9.16.

I was an idiot and put _fini into the wrong register. Duh.
This patch from David Meggy fixes it...

As released in uClibc 0.9.16, regex was being compiled without
wide char support, even when the rest of uClibc was. This led
to anyone using regex segfaulting...

A powerpc patch from Ronald Wahl:

Ok, now i got it after a day of work.

I have had a look into glibc and found the following:

sysdeps/powerpc/dl-machine.c:
...
case R_PPC_JMP_SLOT:
/* It used to be that elf_machine_fixup_plt was used here,
but that doesn't work when ld.so relocates itself
for the second time. On the bright side, there's
no need to worry about thread-safety here. */
{
Elf32_Sword delta = finaladdr - (Elf32_Word) reloc_addr;
...

The comment made me suspicious. The same position in uClibc looks like this:

ldso/ldso/powerpc/elfinterp.c:
...
case R_PPC_JMP_SLOT:
{
unsigned long targ_addr = (unsigned long)_dl_linux_resolve;
int delta = targ_addr - (unsigned long)reloc_addr;
...

When I change it to the following it works:
...
case R_PPC_JMP_SLOT:
{
unsigned long targ_addr = *reloc_addr;
int delta = targ_addr - (unsigned long)reloc_addr;
...

I hope it will not break anything. Can anyone review this change and
commit it into CVS?

thanks,
ron

Add in 'ldso' to directory list since 'make clean' was not recursing
into it.

Don't link to us.kernel.org

fix typo

Update from upstream

For arm use -mcpu for the moment, since it seems to work

typo fixes

Make sure we have __linux__ defined

Manditory typo..

Final update for 0.9.16

Patch from Simon Rowe to try and build asm libm code
only when HAS_FPU is set. If you don't have an FPU
then usm FPU code isn't going to help much...

Patch from Stefan Allius, rebuild extra/config/conf if it is missing
following a make clean

Patch from Stefan Allius: avoid implicit casting of void *(64bit) to int(32bit)

Re-enable the strchrnul and rawmemchr tests

Scare people away from enabling locale support for now.

Disable ldso debugging. It should not be on by default.

Use NATIVE_CC. Don't hard code using 'gcc'.

Patch from Stefan Allius for libgcc multilib support

this is the last patch, we need to make the support of multitarget libgcc
complete.

---------------------------------
In ldso/ldso/Makefile
I added the CPU_LDFLAGS-y to the LDFLAGS
---------------------------------
In libc/Makefile
I set the LDFLAGS for the script get-needed-objects.sh with CPU_LDFLAGS-y
---------------------------------
In extra/scripts/get-needed-object.sh
we now use the LIBGCC from Rules.mak and call LD with LDFLAGS
(==CPU_LDFLAGS-y). Addtionally I grep the NM output, to fix the unresolved
external __GLOBAL_OFFSET_TABLE__ on SuperH targets.
---------------------------------

Disble unimplemented function prototypes

Patch from Stefan Allius to fixup SuperH ARCH_HAS_MMU and ARCH_HAS_FPU

Initial checkin.
