2011-07-15  Jakub Jelinek  <jakub@redhat.com>

	* config/linux/wait.h (do_spin): New inline, largely copied
	from do_wait, just don't do futex_wait here, instead return true if
	it should be done.
	(do_wait): Implement using do_spin.
	* config/linux/mutex.h (gomp_mutex_lock_slow): Add an int argument
	to prototype.
	(gomp_mutex_lock): Use __sync_val_compare_and_swap instead of
	__sync_bool_compare_and_swap, pass the oldval to
	gomp_mutex_lock_slow.
	* config/linux/mutex.c (gomp_mutex_lock_slow): Add oldval argument.
	If all mutex contenders are just spinning and not sleeping, don't
	change state to 2 unnecessarily.  Optimize the loop when state has
	already become 2 to use just one atomic operation per loop instead
	of two.
	* config/linux/ia64/mutex.h (gomp_mutex_lock_slow): Add an int argument
	to prototype.
	(gomp_mutex_lock): Use __sync_val_compare_and_swap instead of

	gomp_mutex_lock_slow.

	PR libgomp/49490
	* iter.c (gomp_iter_static_next): For chunk size 0
	only use n ceil/ nthreads size for the first
	n % nthreads threads in the team instead of
	all threads except for the last few ones which
	get less work or none at all.
	* iter_ull.c (gomp_iter_ull_static_next): Likewise.
	* env.c (parse_schedule): If OMP_SCHEDULE doesn't have
	chunk argument, set run_sched_modifier to 0 for static
	resp. 1 for other kinds.  If chunk argument is 0
	and not static, set value to 1.
