The static program builds in libc were getting multiple
definition errors between dl-sysdep and dl-support.

GCC 4.5 was able to tell that BAR was read-only and zero, and
elided the load. Which caused the pattern match to fail.

The function __set_cr27() uses the `ble`
instruction without marking the link register
r31 as clobbered. This change adds r31 to the
list of clobbers. The TLS thread register is
cr27 and is set by calling __set_cr27().
The initial implementation of makecontext()
supported only 8 arguments. This change adds
support for unlimited argument processing given
a large enough stack.
Adjust the value of SOCK_CLOEXEC to match the kernel
value used for accept4. This has never worked in the
past, and all old applications are broken, therefore
we change this value to match the kernel value.
Update F_SETOWN_EX and F_GETOWN_EX. Rearrange
the file to match other targets, reducing future
diffs against other targets and making maintenance
easier.
microMIPS is a variable-length encoding of the MIPS32 instruction set
(plus some extra instructions). As it supports almost all of MIPS32,
assembly sources in glibc do not generally need changes to work with
microMIPS, but dl-trampoline.c contains some code with a hardcoded
assumption that three instructions occupy twelve bytes. This patch
fixes this code for microMIPS by using the difference between two
labels to let the assembler calculate the relevant length.
Similar to the problems I fixed for posix_fallocate
<http://sourceware.org/ml/libc-ports/2008-12/msg00007.html> and
fallocate <http://sourceware.org/ml/libc-ports/2009-05/msg00031.html>,
MIPS64 posix_advise also needs fixes to use the correct syscall
interfaces. Although the existing n32 posix_fadvise64 is OK, getting
posix_fadvise from syscalls.list does not work correctly, as this
function is supposed to return an error code instead of storing it in
errno as the generic syscall implementations from syscalls.list do.
In the switch to NPTL the pthrad_mutex_t, pthread_cond_t,
and pthread_rwlock_t structures were made binary compatible
with the Linuxthread versions. However, their aligment when
embedded in other structures was changed. When rebuilding
libstdc++ this was detected, and the following changes return
the structures to their original Linuxthreads alignments.

* sysdeps/unix/sysv/linux/hppa/nptl/bits/pthreadtypes.h:
Use correct alignment for pthread_mutex_t, pthread_cond_t,
and pthread_rwlock_t.
Cast oldval to the same type as ret to avoid warnings when
including atomic.h.
2009-11-22 Carlos O'Donell <carlos@codesourcery.com>
* sysdeps/unix/sysv/linux/hppa/bits/atomic.h: Avoid warnings
by casting oldval to int.
Place socket.h in the correct location.

[BZ #6676]
* sysdeps/unix/sysv/linux/hppa/socket.h: Move from here...
* sysdeps/unix/sysv/linux/hppa/bits/socket.h: ... to here.
The current ELF_MACHINE_LOAD_ADDRESS used by the generic
function pointer code was not safe for use before relocation.
The macro has been rewritten to use only PC relative loads.
2009-11-15 Carlos O'Donell <carlos@codesourcery.com>
* sysdeps/hppa/dl-fptr.h: Update copyright year.
Reduce ELF_MACHINE_BOOT_FPTR_TABLE_LEN to 64.
Implement ELF_MACHINE_LOAD_ADDRESS using PC relative loads.
Several constants are now defined in a generic file and no longer
need to be defined in the hppa specific file.
2009-11-15 Carlos O'Donell <carlos@codesourcery.com>
* sysdeps/unix/sysv/linux/hppa/nptl/lowlevellock.h:
Remove FUTEX_WAITERS, FUTEX_OWNER_DIED, and FUTEX_TID_MASK.
[BZ #10527] Provide corrected socket constants that match the
kernel values.

[BZ #10527]
* sysdeps/unix/sysv/linux/hppa/socket.h: New file.
[BZ #6676] Use PIC relocations in start.S to support the use of -fPIE
on hppa.
2009-11-15 Carlos O'Donell <carlos@codesourcery.com>
[BZ #6676]
* sysdeps/hppa/elf/start.S: Use R_PARISC_DLTIND* relocations
to support -fPIE.
[BZ #10920] Use the new generic override to specify the hppa
specific libgcc_s.so.4 version number. Remove the files which
hppa no longer has to duplicate in order to accomplish
overriding libgcc_s.so version number.
