Log:
Add oacc_kernels_p argument to pass_parallelize_loops

2016-01-18  Tom de Vries  <tom@codesourcery.com>

	* omp-low.c (set_oacc_fn_attrib): Make extern.
	* omp-low.h (set_oacc_fn_attrib): Declare.
	* tree-parloops.c (struct reduction_info): Add reduc_addr field.
	(create_call_for_reduction_1): Handle case that reduc_addr is non-NULL.
	(create_parallel_loop, gen_parallel_loop, try_create_reduction_list):
	Add and handle function parameter oacc_kernels_p.
	(find_reduc_addr, get_omp_data_i_param): New function.
	(ref_conflicts_with_region, oacc_entry_exit_ok_1)
	(oacc_entry_exit_single_gang, oacc_entry_exit_ok): New function.
	(parallelize_loops): Add and handle function parameter oacc_kernels_p.
	Calculate dominance info.  Skip loops that are not in a kernels region
	in oacc_kernels_p mode.  Skip inner loops of parallelized loops.
	(pass_parallelize_loops::execute): Call parallelize_loops with
	oacc_kernels_p argument.
	(pass_parallelize_loops::clone, pass_parallelize_loops::set_pass_param):
	New member function.
	(pass_parallelize_loops::bool oacc_kernels_p): New member var.
	* passes.def: Add argument to pass_parallelize_loops instantation.
