New Revision: 132769

URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=132769
Log:
	* team.c (gomp_thread_start): Initialize ts.active_level.
	* sections.c (GOMP_parallel_sections_start): Pass count
	as second argument to gomp_resolve_num_threads, don't adjust
	num_threads after the call.
	* env.c (gomp_thread_limit_var): Initialize to ULONG_MAX.
	(gomp_remaining_threads_count, gomp_remaining_threads_lock): New
	variables.
	(initialize_env): Initialize gomp_remaining_threads_count and
	gomp_remaining_threads_lock if needed.
	(omp_get_thread_limit): Return INT_MAX if gomp_thread_limit_var
	is larger than INT_MAX.
	* libgomp.h (struct gomp_team_state): Add active_level field.
	(gomp_remaining_threads_count, gomp_remaining_threads_lock): New
	decls.
	* loop.c (gomp_parallel_loop_start): Pass 0 as second argument
	to gomp_resolve_num_threads.
	* parallel.c: Include limits.h.
	(gomp_resolve_num_threads): Add count argument.  Use current thread's
	active_level rather than level when checking nest-var or
	max-active-levels-var.  Implement OMP_THREAD_LIMIT limitation of
	total number of OpenMP threads.  If second argument is non-zero,
	don't return more than that number if dyn-var is true.
	(GOMP_parallel_start): Pass 0 as second argument to
	gomp_resolve_num_threads.
	(GOMP_parallel_end): Decrease gomp_remaining_threads_count
	if gomp_thread_limit_var != ULONG_MAX.
	(omp_in_parallel, omp_get_active_level): Implement using
	ts.active_level.
