New Revision: 198884

URL: http://gcc.gnu.org/viewcvs?rev=198884&root=gcc&view=rev
Log:
	* cfgloop.h (struct loop): Add safelen and force_vect fields.
	* function.h (struct function): Add has_force_vect_loops field.
	* omp-low.c (expand_omp_simd): If !broken_loop, create loop for
	the simd region and set safelen and force_vect fields in it.
	* tree-vectorizer.c (vectorize_loops): If loop has force_vect set,
	vectorize it even if flag_vectorize isn't set.  Clear loop->force_vect
	after vectorization.
	* tree-ssa-loop.c (gate_tree_vectorize): Return true even
	cfun->has_force_vect_loops.
	* tree-ssa-loop-ivcanon.c (tree_unroll_loops_completely_1): Don't
	unroll loops with loop->force_vect.
	* tree-vect-data-refs.c (vect_analyze_data_ref_dependence): For
	unknown or bad data dependency, if loop->safelen is non-zero, just
	decrease *max_vf to loop->safelen if needed and return false.
	* tree-if-conv.c (main_tree_if_conversion): If-convert also loops with
	loop->force_vect.
	(gate_tree_if_conversion): Return true even if
	cfun->has_force_vect_loops.
