Subject: tree-data-ref.c (analyze_array_indexes, [...]): Use VEC instead of VARRAY.
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9cbb7989ef4aecb7cc18400bbfba432fad279471;p=platform%2Fupstream%2Fgcc.git

tree-data-ref.c (analyze_array_indexes, [...]): Use VEC instead of VARRAY.

	* tree-data-ref.c (analyze_array_indexes, analyze_array,
	init_data_ref, access_functions_are_affine_or_constant_p,
	free_data_refs): Use VEC instead of VARRAY.
	* tree-data-ref.h (data_reference): Change the type of
	access_fns to VEC(tree,gc)*.
	(DR_ACCESS_FN, DR_NUM_DIMENSIONS): Use VEC instead of VARRAY.
