3680f14a7d [hppa] Fix incorrect stack frame usage in vfork. 
In a multithreaded environment the call to vfork was
incorrectly creating a stack frame. Given that the
child unwinds the stack frame first to call exec, it
will corrupt any values the parent stored in the stack
frame. The solution is to avoid creating a stack frame
unless required to call an error function, in which case
we are assured no child was created.

c14e796ff6 hppa: Update nptl/pthread.h to match generic file 2010-06-07 14:46:19 +02:00

b80ec53691 Add correct aligment to pthread_*_t structures. 
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.

2009-11-25  Carlos O'Donell  <carlos@codesourcery.com>

	* sysdeps/unix/sysv/linux/hppa/nptl/bits/pthreadtypes.h:
	Use correct alignment for pthread_mutex_t, pthread_cond_t,
	and pthread_rwlock_t.

a2ed3d2a8e Remove constants which are now defined in generic file. 
Several constants are now defined in a generic file and no longer
need to be defined in the hppa specific file.

	* sysdeps/unix/sysv/linux/hppa/nptl/lowlevellock.h:

8ef75725ce Use LIBGCC_S_SO to override generic version. 
[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.

be0f2008ac Implement new NPTL POSIX Threads ABI for HPPA. 
This version of the NPTL POSIX thread ABI for hppa does
not break backwards compatibility with the the old
Linuxthreads ABI, and is therefore suitable for release
by distributions.
